Speaker 1 (00:04):
I'm Ebony Money and I'm Rick Schwartz. Welcome to Amazing Wildlife,
where we explore unique stories of wildlife from around the
world and uncovered fascinating animal facts. This podcast is a
production of My Heart Radio in the San Diego Zoo,
Wildlife Alliance and international nonprofit conservation organization behind the San
Diego Zoo and Safari Park. Today we're talking about an
(00:26):
egg laying mammal. The platypus is so rare that when
they were first discovered, European explorers had a hard time
convincing scientists that they were real. Today we know they're real,
but not too many people have ever seen one in person.
The San Diego Zoo Safari Park is currently the only
(00:46):
zoo outside of Australia to house platypuses. Rick, that's pretty amazing.
How did that come about? It really is amazing, Ebony.
I can't stress enough just how special it is to
have them here for all of us in San Diego
and those who have visited them at the Safari Park.
Bearer Wrung the male and Eve the female arrived from
(01:07):
Australia's Torongo Zoos Sydney, but honestly, the whole thing started
long before they even arrived in San Diego. Rick, what
did it take to make all of that happen? Oh,
well happening. It took a lot more than most people
might think. But before we get into everything that happened
for these two platypuses, I want to share something with
our listeners that they may not know. Now, for most
(01:30):
of our listeners, if not all of our listeners, they
know about the conservation work that the San Diego Zoo
Wildlifelines does all over the world. But what they may
not know is that zoos work together across the world
in many ways. We collaborate in wildlife care, species survival plans,
conservation efforts, and so much more. And these kind of
international collaborative efforts were a big part of making sure
(01:52):
the platypuses were able to enjoy their move to the
San Diego Zoo Safarire Park. We also work directly with
the Australian government for le was on the move. I mean,
like I said, a lot of things happened long before
they landed here in San Diego. Some of the work
in preparation for this included building a special, brand new
habitat specifically for platypuses, with special water features, denning areas
(02:14):
and outdoor access, custom lighting, and even special areas just
for their food to be kept in. And then we
sent staff over to Australia to work side by side
with platypus care staff for several months so they could
learn everything, and I mean everything they need to know
about platypus care and health. But it didn't stop there.
(02:35):
When it came time for Very Rung and Eve to
come to San Diego, their team of humans came with
them and stayed for several weeks here in San Diego
to make sure everything went smoothly. It really was a
big team effort to make sure everything went perfectly. I
like that their team of humans, So it really took
a lot of people, it sounds like, to make sure
(02:57):
these two platypuses had everything they needed. Behind the scenes,
How did the Torongo Zoo Sydney and San Diego Zoo
Wildlife Alliance go about transporting the two platypuses from one
continent to another, well, have any Like I mentioned, there
was a lot of staff involved making sure they had
all the needed things for their move. The two were
(03:19):
flowing to the US and specially designed platypus secure carriers
for travel. These secure carriers had insulated panels, special ventilation cameras,
as well as temperature and sound loggers, so this allowed
us to really make sure everything was just perfect for them,
and many months of preparation and training went into ensuring
the successful transfer of the platypuses. It's really impressive to
(03:40):
think this many people came together to make this happen.
So what's all this hard work for. What's the benefit
of learning about wildlife from the entire other side of
the globe? Yeah? I mean this is really really important,
and I'm so glad you asked that because a lot
of times people look at the great efforts we go
into for something like this and like, why would you
(04:01):
spend that much time and money to do that? But see,
here's the thing, like all wildlife at the San Diego
Zoo or the San Diego Zoo Safire Park, when people
have an opportunity to see them up close, their natural
curiosity kicks in. They instantly want to learn more about
that wildlife. And as they learn more about them, especially
these unique mammals from Australia, they understand how important wildlife
(04:23):
is and how many of them need our help. To
ensure a safe and healthy future for all of them.
These two platypuses at the Safire Park have inspired countless
people from all over the world who have visited this
fire park every day, helping us raise awareness for this
unique species. And as people fall in love with them, well,
guess what they want to protect them like we do,
(04:43):
so that gets them involved in conservation, and when we
all work together, conservation works so much better. I think
it would be fair to say that these two are
truly ambassadors for their kind. Enric You're a San Diego
Zoo Wildlife Alliance Ambassador. But what does it mean to
be a wildlife ambassador? Well, Ebany, it's so very important
(05:04):
to connect people with wildlife, especially on a personal level,
and honestly, there's no better representative to do so than
the wild life itself. I mean, sure, you can watch
videos online and and see nature documents, all of which
are very important components to learning more about wildlife, but
when you can see them in person, you can see
how they move, you can catch maybe a glimpse of
(05:24):
them looking right back at you. Nothing can replace that
personal connection. Wildlife ambassadors are individuals that help share the
story and plight of their kind with the people who
may otherwise never know about their species, much less the
challenges they might face in the wild. So specifically, as
wildlife ambassadors, what do the platypus is at the San
(05:46):
Diego Zoo Safari Park helped to educate people about Honestly,
for the platypus, that is very specific. You know, they
help teach people about the importance of fresh water for
both humans and wildlife. See platypus is in the wild
are facing so many challenges with pollution in their waterways
and the habitats being affected by climate change. When we
see freshwater wildlife having these challenges, that means we will too.
(06:10):
We all need healthy fresh water systems to live. That's
just a simple fact. This is another example of how
all life, humans, plants, and animals are interconnected. We all
rely on the health of the same resources, and when
we learn about what is happening to the charismatic platypus
and other freshwater wildlife, we instinctively want to help. We
can all be part of the solution and protect wildlife
(06:32):
like the platypus through water conservation measures and practices that
help slow or mitigate climate change. So rick the more
that we talk about animals and different species, the more
I've come to realize that oftentimes animals play a very
important role in their habitats that maybe we don't even realize.
So what's the role of the platypus in its environment? Yeah,
(06:56):
and that's a really good question, because again we're talking
about the fresh water wildlife and everything else, and platypus
is as cute and as amazing and adorable and scientifically
unusual as they are, they also do have a very
important role in the whole ecosystem there. You know, they
are consumers of shrimp, crayfish, insect larvae, worms, and other things,
and then they're consumed by snakes and birds and other
(07:18):
predators such as crocodiles, and so their role in part
of that food chain is very important. And like anything,
when we take out one of those links, or we
lose one of those links in the food chain, everything
starts to become unraveled. So, like any species out there,
sometimes we have to look past their adorable nous or
their curiosity or how interesting they are. But they do
have a very important role in the ecosystem. Honestly, the
(07:41):
more I learned about the platypus, the more I realized
just how cool of an animal it is. It seems
like an amazing experience to have a chance to see
a platypus up close and personal at the San Diego
Zoo Safari Park. Obviously, Rick the SAPARi Park is pretty big.
Where can guess find the platypus. Yeah, you know, it's
just about a year before the platypus has arrived at
(08:03):
the Safari Park avenue we opened walk About Australia. This
is a multi species habitat where you can stroll along kangaroos,
wallabies and you know, even see the elusive and impressive Castlewary.
But in that same area we also built that platypus
habitat we're talking about earlier, where guests can see them swimming, eating,
or just you know, taking a little nap. But if
you're planning a visit specifically for them, and I'm talking
(08:23):
to you listeners, if you're planning a visit just to
visit our platypus, I always recommend heading up to the
Walk About Australia are your first thing, because most animals
tend to be active in the morning. Oh and if
you want to see them, but you don't have time
to visit the Safari parker, it's gonna be a while
before you can visit. Here's your insider tip. Just go
to the Safari Parks website s DZ Safari Park dot
(08:44):
org and click on the Wildlife Live Cams and then
select Platypus Cam and there you'll have it right in
front of you, a front row seat to the main
pool of the platypus habitat. And you can click on
that whenever you want lunch break, you know, weekends, whatever,
you whenever you want to enjoy some platypus time. You're
full of all kinds of tips. Just ahead, we're going
to talk to the lead wild left care specialists working
(09:06):
with mammals at the San Diego Zoo Safari Park, Louisa
Choa and Veterinary Clinical Operations Manager Meredith Clancy. But first
this now it's time for the San Diego Zoom Minute,
an opportunity for you to learn what's new at the
San Diego Zoo and Safari Park. A ten year old
(09:28):
boy and his family received a San Diego Zoo Wildlife
Alliance lifetime membership card as part of the ongoing celebration
of the San Diego Zoo Safire Parks fiftieth Anniversary made
ten to mark fifty years since the opening of the
San Diego Zoo Safari Park. On that day, Ethan was
the fiftieth guests to enter the Safarire Park. The gift
allows for unlimited visits to the Safarire Park and San
(09:51):
Diego Zoo, where he can explore and connect with wildlife
for years to come. Did you know the word platypus
is derived from a Greek word meaning flat foot. The
correct plural ending is s, making platypus is preferred over platypi.
I don't know. I want to introduce Louise oh Choa,
(10:17):
a lead wildlife care specialists working with mammals at the
San Diego Zoos Safari Park, and Meredith Clancy, the veterinary
Clinical Operations manager, also at the San Diego Zoos Safari Park. Hi,
Hi there, Hi, thanks for having us. Yes, So the
San Diego Zoue Safari Park has cared for the platypus
(10:38):
is now for just over two years. Louise, what can
you tell us about their habitat there at the Safari Park?
So our two platypus have a house that was built
just for them. And right now the two platypus have
access to three huge pools that the guests can see themselves.
So both of our platypus have access to those three areas,
(11:00):
and then they have a holding area in the back.
They have some tunnels, they have some nest boxes, a
huge container of dirt that we call the earth tank
that just has a couple of feet of dirt and
other material that our platypus will grow through. Yeah, that's
just the part building. So just curious, why does the
platypus um need so much access to all that water?
(11:20):
Are are you mimicking their natural habitat or what's happening? Yeah,
So platypus are found on the eastern most the Eastern
coast and southern coast of Australia. They are semi aquatic
mammals and they do most of their hunting for food
and foraging in the water. So we have to provide
them that same ability here at the Safari Park. So
in the wild, when platypus hunt for food, they close
(11:41):
their eyes, they close their ears and they go into
water and they rely on something in their bill called
an electric receptor. So in order for us to mimic that,
we have to kind of do the same thing. So
we have large pools of water and inside those pools
of water we offer them a few different types of food.
In the wild, most of the calories from platypus come
from crayfish or in Australia they called them yabbies, So
we do the same up here at the park. We
(12:02):
give them some preefish. We put them in the pools
and they have to be live the platypus to find them.
Those are electric receptors in the bill will activate once
they're swimming in the water and they'll pick up small
signals from living animals and that will help them really
hone in on where that moving venions in the water. So, Maren,
the platypuses are such a unique animal. How did you
(12:22):
and your team prepared to care for such a unique animal?
That's such a great question. We definitely had to do
a lot of preparation to think about having this brand
new species to the San Diego Zoo Wildlife Alliance family.
So we were very fortunate. We have friends at the
Tarronga Zoo that we're really helpful and instrumental in making
sure that we understood the unique needs of this special
(12:45):
creature and also understood what kind of habitat they needed,
their special diet, and then even little small things like
the transport crates or how we were going to feed
them and how we would source those foods. I think
the other really awesome thing that we got to do
when we were introducing this species into our wonderful Australia
habitat was really learn a lot about monotreams and platypus
(13:09):
in particular, and how it is that, what kind of
medicine they need, what kind of care by humans they
need when they're living with us, and then learn a
lot about their story as how they exist out in
the wild. And that allowed us to really know and
be ready as ready as you can be right before
the platypus arrived to be able to house them and
really provide for them a unique habitat for them to
(13:31):
thrive in. So we've talked a lot about the fact
that platypuses are so unique, but what exactly makes the unique?
What's like an example of what makes them just stand out? Well,
they are a special type of mammal. So I guess
if we start off from that point of you and I,
and most animals that we see in zoo settings are mammals,
(13:52):
so they are warm blooded, they have hair, they could
produce milk, and that's where a lot of the similarities
that platypus have with other animals, and that's kind of
where it stops. And that's really what makes some unique
because they have a bunch of little things and characteristics
from other groups or species and they kind of put
them all together in one animal. So sometimes they're referred
to as duck build platypus, so they're build in the
front of their face. It's just called a duck bill,
(14:12):
but it actually that's that's that's much of the very
resemblance to an actual duck bill. It's not very hard
like a bird beak would be. It's kind of soft
and pliable, kind of feels like a wet race or
like on a pencil, And when you really take an
intense look at it, you can see the pores on
there and really that's where the elector receptors live, and
that's a really unique way that a mammal would hunt
in general. So then moving down its body from those
luct receptors, they don't really have the best vision. They're
(14:34):
mostly nocturnal animals. Most of their hunting is underwater, and
then they live in burrows underground, so they don't really
have to need good vision. Um they have a nice
little double coat because they are really good allowed cold tolerance.
Not really good about heat, but they can stand cold.
This pretty well. Never really unique stomach to them as well.
They kind of go straight from their esophagus right into
the intestines, so it's a really basic kind of g
(14:55):
I trap. And then they have their spur. The males
are born with the venomous spur, which is really unique
for ma. Almost a lot of mammals have that ability.
They are venomous when they are breeding season, and so
when platypus are born, both males and females, they del
a small little spur brought on the inside of their
bottom two feet, and as they grow and mature, the
males will continue to develop that females will eventually drop
(15:15):
that off. But when a male hits full maturity and
he's an adult he which is about two years old,
they will have that venom start to be produced, and
in the breeding season it'll definitely increase production. So that's
in a gist roundabout way that. Oh, and and they
lay eggs too, by the way, So all these different
two So they have spurs, they have bills, they lay eggs,
(15:37):
just all sorts of weird things. Dr Clans, Do you
have anything to add so much? I'm sure I was
gonna just say, I think, um, yeah. The fact that
they're egg laying mammals makes them pretty unique, and paired
with their cousin the only other montorym that's still alive,
which is the achidna, which we also have at the
San Diego Zu Safari Park. But it's so unique that
they lay eggs, and it was actually not a fact
(15:57):
that most people knew about those animals, And we still
really don't understand a lot of what happens. When a
platypus mom to be goes into her burrow, she lays
an egg. It takes about two weeks for it to hatch,
but that about is about as clear as we can be,
and then it slowly develops the puggle, which is the
name for a baby platypus or a baby a kidney.
(16:18):
The puggle slowly develops into its more adult type features.
But a lot of that information we're still learning a
lot about but I think the way Luise put it
where they kind of have borrowed from birds, they fired
a little bit of their skeletal anatomy from reptiles, how
they excrete waste, and how they process food. So they're
like a little unique package of all the best methods
(16:40):
that work out for them to be. Like, we've talked
about a semi aquatic mammal, So the fact that the
platypus is venomous, how does that impact your work if
at all? Yeah, I think it probably impacts a lot
of the work that Louise would have to do and
his teammates if they're having to handle or move the
mail platypus. We just have to be very cautious to
(17:01):
make sure that we're being both safe for the animal
and safe for the people. And Louise can probably talk
more about it, but there's a very specialized training to
make sure that you can hold the animal by the
tail and staying away from that venomous spur. But for
our team, what it often means is if we need
to do something with that male platypus, we would need
to give that animal sedatives or anesthetics so that it
(17:23):
would be asleep and that way it's not stressed and
it's not thinking about needing to invenomate anyone, and we
can make sure that we're staying far away from the
potential danger zone and Louise. So the platypus is not
only venomous, but it's also nocturnal. How does some of
these characteristics impact the work of you and your team?
(17:43):
I presented a whole new challenge when I started working
with the platypus, because not only do we when we
enter the platypus house as a guest, who notice it's
pretty dark going in, and then um, you know when
you're looking at the platypus there in their nighttime. We
have a reverse light cycle at the platypus house, but
we did recently at the Platypus house is actually match
at the time in Sydney, Australia to the time inside
the platypus house in San Diego. So right now, what
(18:05):
we want to try to do is to get the
platypus to feel and experience the same sunlight as the
platypus in city would experience. So if in the summer
they have longer days, that system is going to know
and it's going to adjust that lighting period. So the
biggest challenge for us moving forward from here is just
wrapping my brain around this time change and all these
kind of things, and when the seasons change. We also,
(18:26):
because we are inside a platypus house and you can
kind of control some of the things, we try to
have environmental changes in queues go along as well. So
try and wrap my head around what does that mean
would a platypus in the wild experience at that time,
and how can we keep the platypus in that same
time frame? So what's the benefit of learning um and
taking such great detail to learn about a species from
(18:49):
the other side of the globe. So one of the
really neat things about the platypus and a lot of
our Australian mammal counterparts and all the animals that we
care for in our Australia team is that Australia is
very similar to southern California in some of the threats
that are wildlife and even are people that live with
wildlife face. There's a lot of habitat destruction, there's a
(19:10):
lot of drought and lack of water, which if you're
a semi aquatic mammal like the platypus. You really need
those rivers to be there, and there's wildfire risk, some
of that mitigated by climate change. So I think one
of the neat things is that the platypus can serve
as an ambassador that maybe outside of the Southwest wildlife
that we have that can also tell that story. It's
(19:31):
a really unique animal for people to come to San
Diego and see and be able to maybe resonate with
some of those thoughts and concerns about, you know, us
caring for wildlife both under human care and out in
the wild. I think the other really unique thing is
outside of getting on a plane and flying to Sydney
or many of the other cities in Australia, you're not
(19:51):
going to be able to see a platypus because they
don't exist outside of Australia except for our too lucky
ambassadors that we have here. So it's a really opportunity
for our guests and those that are able to come
to the Safari Park to be able to experience this
really truly amazing creature that they may not otherwise be
able to see. Louise, what's the best part of your
position in your favorite thing about working with the platypus.
(20:16):
I'd say my favorite part about working at the platypus
house and the platypus is going up to the guest
side when the park is open and looking at guests,
watching them look at the platypus for the first time.
I think it's really special, really unique opportunity. Sometimes people say,
when they see a platypus, let's say, how much smaller
it is, and they originally thought just how different it looks,
and they'll just kind of stand and stare at the
(20:37):
platypus for a few minutes, And I just that's a
really unique opportunity I think for anybody to see. So
that's a favorite part in Meredith. I think for me,
the platypus really represents that there's so much for us
to continue to learn, and even years into your career,
you get to experience working with a new species or
learning more about how to take better care of the
(20:58):
wildlife under our care. And it's a privilege to be
entrusted to care for those two and get to become
almost an expert in an animal that you never thought
you would be lucky enough to work with. Thank you
so much. It has been great talking with you both.
We've been speaking with Louise Ochoa, a lead wildlife care

where we explore unique stories of wildlife from around the
world and uncovered fascinating animal facts. This podcast is a
production of My Heart Radio in the San Diego Zoo,
Wildlife Alliance and international nonprofit conservation organization behind the San
Diego Zoo and Safari Park. Today we're talking about an
(00:26):
egg laying mammal. The platypus is so rare that when
they were first discovered, European explorers had a hard time
convincing scientists that they were real. Today we know they're real,
but not too many people have ever seen one in person.
The San Diego Zoo Safari Park is currently the only
(00:46):
zoo outside of Australia to house platypuses. Rick, that's pretty amazing.
How did that come about? It really is amazing, Ebony.
I can't stress enough just how special it is to
have them here for all of us in San Diego
and those who have visited them at the Safari Park.
Bearer Wrung the male and Eve the female arrived from
(01:07):
Australia's Torongo Zoos Sydney, but honestly, the whole thing started
long before they even arrived in San Diego. Rick, what
did it take to make all of that happen? Oh,
well happening. It took a lot more than most people
might think. But before we get into everything that happened
for these two platypuses, I want to share something with
our listeners that they may not know. Now, for most
(01:30):
of our listeners, if not all of our listeners, they
know about the conservation work that the San Diego Zoo
Wildlifelines does all over the world. But what they may
not know is that zoos work together across the world
in many ways. We collaborate in wildlife care, species survival plans,
conservation efforts, and so much more. And these kind of
international collaborative efforts were a big part of making sure
(01:52):

sent staff over to Australia to work side by side
with platypus care staff for several months so they could
learn everything, and I mean everything they need to know
about platypus care and health. But it didn't stop there.

like that their team of humans, So it really took
a lot of people, it sounds like, to make sure
(02:57):
these two platypuses had everything they needed. Behind the scenes,
How did the Torongo Zoo Sydney and San Diego Zoo
Wildlife Alliance go about transporting the two platypuses from one
continent to another, well, have any Like I mentioned, there
was a lot of staff involved making sure they had
all the needed things for their move. The two were
(03:19):
flowing to the US and specially designed platypus secure carriers
for travel. These secure carriers had insulated panels, special ventilation cameras,
as well as temperature and sound loggers, so this allowed
us to really make sure everything was just perfect for them,
and many months of preparation and training went into ensuring
the successful transfer of the platypuses. It's really impressive to
(03:40):
think this many people came together to make this happen.
So what's all this hard work for. What's the benefit
of learning about wildlife from the entire other side of
the globe? Yeah? I mean this is really really important,
and I'm so glad you asked that because a lot
of times people look at the great efforts we go
into for something like this and like, why would you
(04:01):
spend that much time and money to do that? But see,
here's the thing, like all wildlife at the San Diego

have an opportunity to see them up close, their natural

These two platypuses at the Safire Park have inspired countless
people from all over the world who have visited this
fire park every day, helping us raise awareness for this
unique species. And as people fall in love with them, well,
guess what they want to protect them like we do,
(04:43):
so that gets them involved in conservation, and when we
all work together, conservation works so much better. I think
it would be fair to say that these two are
truly ambassadors for their kind. Enric You're a San Diego
Zoo Wildlife Alliance Ambassador. But what does it mean to
be a wildlife ambassador? Well, Ebany, it's so very important
(05:04):
to connect people with wildlife, especially on a personal level,
and honestly, there's no better representative to do so than
the wild life itself. I mean, sure, you can watch
videos online and and see nature documents, all of which
are very important components to learning more about wildlife, but
when you can see them in person, you can see
how they move, you can catch maybe a glimpse of
(05:24):
them looking right back at you. Nothing can replace that
personal connection. Wildlife ambassadors are individuals that help share the
story and plight of their kind with the people who
may otherwise never know about their species, much less the
challenges they might face in the wild. So specifically, as
wildlife ambassadors, what do the platypus is at the San
(05:46):
Diego Zoo Safari Park helped to educate people about Honestly,
for the platypus, that is very specific. You know, they
help teach people about the importance of fresh water for
both humans and wildlife. See platypus is in the wild
are facing so many challenges with pollution in their waterways
and the habitats being affected by climate change. When we
see freshwater wildlife having these challenges, that means we will too.
(06:10):
We all need healthy fresh water systems to live. That's
just a simple fact. This is another example of how
all life, humans, plants, and animals are interconnected. We all
rely on the health of the same resources, and when
we learn about what is happening to the charismatic platypus
and other freshwater wildlife, we instinctively want to help. We
can all be part of the solution and protect wildlife
(06:32):
like the platypus through water conservation measures and practices that
help slow or mitigate climate change. So rick the more
that we talk about animals and different species, the more
I've come to realize that oftentimes animals play a very
important role in their habitats that maybe we don't even realize.
So what's the role of the platypus in its environment? Yeah,
(06:56):
and that's a really good question, because again we're talking
about the fresh water wildlife and everything else, and platypus
is as cute and as amazing and adorable and scientifically
unusual as they are, they also do have a very
important role in the whole ecosystem there. You know, they
are consumers of shrimp, crayfish, insect larvae, worms, and other things,
and then they're consumed by snakes and birds and other
(07:18):
predators such as crocodiles, and so their role in part
of that food chain is very important. And like anything,
when we take out one of those links, or we
lose one of those links in the food chain, everything
starts to become unraveled. So, like any species out there,
sometimes we have to look past their adorable nous or
their curiosity or how interesting they are. But they do
have a very important role in the ecosystem. Honestly, the
(07:41):
more I learned about the platypus, the more I realized
just how cool of an animal it is. It seems
like an amazing experience to have a chance to see
a platypus up close and personal at the San Diego
Zoo Safari Park. Obviously, Rick the SAPARi Park is pretty big.
Where can guess find the platypus. Yeah, you know, it's
just about a year before the platypus has arrived at
(08:03):
the Safari Park avenue we opened walk About Australia. This
is a multi species habitat where you can stroll along kangaroos,
wallabies and you know, even see the elusive and impressive Castlewary.
But in that same area we also built that platypus
habitat we're talking about earlier, where guests can see them swimming, eating,
or just you know, taking a little nap. But if
you're planning a visit specifically for them, and I'm talking
(08:23):
to you listeners, if you're planning a visit just to
visit our platypus, I always recommend heading up to the
Walk About Australia are your first thing, because most animals
tend to be active in the morning. Oh and if
you want to see them, but you don't have time
to visit the Safari parker, it's gonna be a while
before you can visit. Here's your insider tip. Just go
to the Safari Parks website s DZ Safari Park dot
(08:44):
org and click on the Wildlife Live Cams and then
select Platypus Cam and there you'll have it right in
front of you, a front row seat to the main
pool of the platypus habitat. And you can click on
that whenever you want lunch break, you know, weekends, whatever,
you whenever you want to enjoy some platypus time. You're
full of all kinds of tips. Just ahead, we're going
to talk to the lead wild left care specialists working
(09:06):
with mammals at the San Diego Zoo Safari Park, Louisa
Choa and Veterinary Clinical Operations Manager Meredith Clancy. But first
this now it's time for the San Diego Zoom Minute,
an opportunity for you to learn what's new at the
San Diego Zoo and Safari Park. A ten year old
(09:28):
boy and his family received a San Diego Zoo Wildlife
Alliance lifetime membership card as part of the ongoing celebration
of the San Diego Zoo Safire Parks fiftieth Anniversary made
ten to mark fifty years since the opening of the
San Diego Zoo Safari Park. On that day, Ethan was
the fiftieth guests to enter the Safarire Park. The gift
allows for unlimited visits to the Safarire Park and San
(09:51):
Diego Zoo, where he can explore and connect with wildlife
for years to come. Did you know the word platypus
is derived from a Greek word meaning flat foot. The
correct plural ending is s, making platypus is preferred over platypi.
I don't know. I want to introduce Louise oh Choa,
(10:17):
a lead wildlife care specialists working with mammals at the
San Diego Zoos Safari Park, and Meredith Clancy, the veterinary
Clinical Operations manager, also at the San Diego Zoos Safari Park. Hi,
Hi there, Hi, thanks for having us. Yes, So the
San Diego Zoue Safari Park has cared for the platypus
(10:38):
is now for just over two years. Louise, what can
you tell us about their habitat there at the Safari Park?
So our two platypus have a house that was built
just for them. And right now the two platypus have
access to three huge pools that the guests can see themselves.
So both of our platypus have access to those three areas,
(11:00):
and then they have a holding area in the back.
They have some tunnels, they have some nest boxes, a
huge container of dirt that we call the earth tank
that just has a couple of feet of dirt and
other material that our platypus will grow through. Yeah, that's
just the part building. So just curious, why does the
platypus um need so much access to all that water?
(11:20):
Are are you mimicking their natural habitat or what's happening? Yeah,
So platypus are found on the eastern most the Eastern
coast and southern coast of Australia. They are semi aquatic
mammals and they do most of their hunting for food
and foraging in the water. So we have to provide
them that same ability here at the Safari Park. So
in the wild, when platypus hunt for food, they close
(11:41):
their eyes, they close their ears and they go into
water and they rely on something in their bill called
an electric receptor. So in order for us to mimic that,
we have to kind of do the same thing. So
we have large pools of water and inside those pools
of water we offer them a few different types of food.
In the wild, most of the calories from platypus come
from crayfish or in Australia they called them yabbies, So
we do the same up here at the park. We
(12:02):
give them some preefish. We put them in the pools
and they have to be live the platypus to find them.
Those are electric receptors in the bill will activate once
they're swimming in the water and they'll pick up small
signals from living animals and that will help them really
hone in on where that moving venions in the water. So, Maren,
the platypuses are such a unique animal. How did you
(12:22):
and your team prepared to care for such a unique animal?
That's such a great question. We definitely had to do
a lot of preparation to think about having this brand
new species to the San Diego Zoo Wildlife Alliance family.
So we were very fortunate. We have friends at the
Tarronga Zoo that we're really helpful and instrumental in making
sure that we understood the unique needs of this special
(12:45):
creature and also understood what kind of habitat they needed,
their special diet, and then even little small things like
the transport crates or how we were going to feed
them and how we would source those foods. I think
the other really awesome thing that we got to do
when we were introducing this species into our wonderful Australia
habitat was really learn a lot about monotreams and platypus
(13:09):
in particular, and how it is that, what kind of
medicine they need, what kind of care by humans they
need when they're living with us, and then learn a
lot about their story as how they exist out in
the wild. And that allowed us to really know and
be ready as ready as you can be right before
the platypus arrived to be able to house them and
really provide for them a unique habitat for them to
(13:31):
thrive in. So we've talked a lot about the fact
that platypuses are so unique, but what exactly makes the unique?
What's like an example of what makes them just stand out? Well,
they are a special type of mammal. So I guess
if we start off from that point of you and I,
and most animals that we see in zoo settings are mammals,
(13:52):
so they are warm blooded, they have hair, they could
produce milk, and that's where a lot of the similarities
that platypus have with other animals, and that's kind of
where it stops. And that's really what makes some unique
because they have a bunch of little things and characteristics
from other groups or species and they kind of put
them all together in one animal. So sometimes they're referred
to as duck build platypus, so they're build in the
front of their face. It's just called a duck bill,
(14:12):
but it actually that's that's that's much of the very
resemblance to an actual duck bill. It's not very hard
like a bird beak would be. It's kind of soft
and pliable, kind of feels like a wet race or
like on a pencil, And when you really take an
intense look at it, you can see the pores on
there and really that's where the elector receptors live, and
that's a really unique way that a mammal would hunt
in general. So then moving down its body from those
luct receptors, they don't really have the best vision. They're
(14:34):
mostly nocturnal animals. Most of their hunting is underwater, and
then they live in burrows underground, so they don't really
have to need good vision. Um they have a nice
little double coat because they are really good allowed cold tolerance.
Not really good about heat, but they can stand cold.
This pretty well. Never really unique stomach to them as well.
They kind of go straight from their esophagus right into
the intestines, so it's a really basic kind of g
(14:55):
I trap. And then they have their spur. The males
are born with the venomous spur, which is really unique
for ma. Almost a lot of mammals have that ability.
They are venomous when they are breeding season, and so
when platypus are born, both males and females, they del
a small little spur brought on the inside of their
bottom two feet, and as they grow and mature, the
males will continue to develop that females will eventually drop
(15:15):
that off. But when a male hits full maturity and
he's an adult he which is about two years old,
they will have that venom start to be produced, and
in the breeding season it'll definitely increase production. So that's
in a gist roundabout way that. Oh, and and they
lay eggs too, by the way, So all these different
two So they have spurs, they have bills, they lay eggs,
(15:37):
just all sorts of weird things. Dr Clans, Do you
have anything to add so much? I'm sure I was
gonna just say, I think, um, yeah. The fact that
they're egg laying mammals makes them pretty unique, and paired
with their cousin the only other montorym that's still alive,
which is the achidna, which we also have at the
San Diego Zu Safari Park. But it's so unique that
they lay eggs, and it was actually not a fact
(15:57):
that most people knew about those animals, And we still
really don't understand a lot of what happens. When a
platypus mom to be goes into her burrow, she lays
an egg. It takes about two weeks for it to hatch,
but that about is about as clear as we can be,
and then it slowly develops the puggle, which is the
name for a baby platypus or a baby a kidney.
(16:18):
The puggle slowly develops into its more adult type features.
But a lot of that information we're still learning a
lot about but I think the way Luise put it
where they kind of have borrowed from birds, they fired
a little bit of their skeletal anatomy from reptiles, how
they excrete waste, and how they process food. So they're
like a little unique package of all the best methods
(16:40):
that work out for them to be. Like, we've talked
about a semi aquatic mammal, So the fact that the
platypus is venomous, how does that impact your work if
at all? Yeah, I think it probably impacts a lot
of the work that Louise would have to do and
his teammates if they're having to handle or move the
mail platypus. We just have to be very cautious to
(17:01):
make sure that we're being both safe for the animal
and safe for the people. And Louise can probably talk
more about it, but there's a very specialized training to
make sure that you can hold the animal by the
tail and staying away from that venomous spur. But for
our team, what it often means is if we need
to do something with that male platypus, we would need
to give that animal sedatives or anesthetics so that it
(17:23):
would be asleep and that way it's not stressed and
it's not thinking about needing to invenomate anyone, and we
can make sure that we're staying far away from the
potential danger zone and Louise. So the platypus is not
only venomous, but it's also nocturnal. How does some of
these characteristics impact the work of you and your team?
(17:43):
I presented a whole new challenge when I started working
with the platypus, because not only do we when we
enter the platypus house as a guest, who notice it's
pretty dark going in, and then um, you know when
you're looking at the platypus there in their nighttime. We
have a reverse light cycle at the platypus house, but
we did recently at the Platypus house is actually match
at the time in Sydney, Australia to the time inside
the platypus house in San Diego. So right now, what
(18:05):
we want to try to do is to get the
platypus to feel and experience the same sunlight as the
platypus in city would experience. So if in the summer
they have longer days, that system is going to know
and it's going to adjust that lighting period. So the
biggest challenge for us moving forward from here is just
wrapping my brain around this time change and all these
kind of things, and when the seasons change. We also,
(18:26):
because we are inside a platypus house and you can
kind of control some of the things, we try to
have environmental changes in queues go along as well. So
try and wrap my head around what does that mean
would a platypus in the wild experience at that time,
and how can we keep the platypus in that same
time frame? So what's the benefit of learning um and
taking such great detail to learn about a species from
(18:49):
the other side of the globe. So one of the
really neat things about the platypus and a lot of
our Australian mammal counterparts and all the animals that we
care for in our Australia team is that Australia is
very similar to southern California in some of the threats
that are wildlife and even are people that live with
wildlife face. There's a lot of habitat destruction, there's a
(19:10):
lot of drought and lack of water, which if you're
a semi aquatic mammal like the platypus. You really need
those rivers to be there, and there's wildfire risk, some
of that mitigated by climate change. So I think one
of the neat things is that the platypus can serve
as an ambassador that maybe outside of the Southwest wildlife
that we have that can also tell that story. It's
(19:31):
a really unique animal for people to come to San
Diego and see and be able to maybe resonate with
some of those thoughts and concerns about, you know, us
caring for wildlife both under human care and out in
the wild. I think the other really unique thing is
outside of getting on a plane and flying to Sydney
or many of the other cities in Australia, you're not
(19:51):
going to be able to see a platypus because they
don't exist outside of Australia except for our too lucky
ambassadors that we have here. So it's a really opportunity
for our guests and those that are able to come
to the Safari Park to be able to experience this
really truly amazing creature that they may not otherwise be
able to see. Louise, what's the best part of your
position in your favorite thing about working with the platypus.
(20:16):
I'd say my favorite part about working at the platypus
house and the platypus is going up to the guest
side when the park is open and looking at guests,
watching them look at the platypus for the first time.
I think it's really special, really unique opportunity. Sometimes people say,
when they see a platypus, let's say, how much smaller
it is, and they originally thought just how different it looks,
and they'll just kind of stand and stare at the
(20:37):
platypus for a few minutes, And I just that's a
really unique opportunity I think for anybody to see. So
that's a favorite part in Meredith. I think for me,
the platypus really represents that there's so much for us
to continue to learn, and even years into your career,
you get to experience working with a new species or
learning more about how to take better care of the
(20:58):
wildlife under our care. And it's a privilege to be
entrusted to care for those two and get to become
almost an expert in an animal that you never thought
you would be lucky enough to work with. Thank you
so much. It has been great talking with you both.
