No melting mess, no ice runs. The new Dometic CFX
five keeps your food chilled and your ice frozen so
you can stay focused on the hunt. Just load it up,
plug it in, and let it do the rest. I
love using mind on hot pronghorn hunts and at early
season Elk camp. It really is a game changer. Head
(00:23):
to Dometic dot com to learn more about Dometic electric coolers.
Speaker 2 (00:42):
It's time for Why It's the Way it is. Today.
Speaker 3 (00:48):
On Why It's the Way it is, we're going to
talk about eyeballs, which seems kind of funny, but we're
not going to talk about how eyeballs work necessarily. We're
going to talk about where eyeballs sit on an an
animal's head, Okay, meaning, why are a rabbit's like picture
a rabbit in your mind. Why are a rabbit's eyes
(01:08):
kind of buggy and they stick out in their position
way out on the sides of his head, all right?
Compared to why are your eyeballs in the front of
your head and real close together. The answer to that
question is where your eyeballs sit on your head or
where an animal's eyeballs sit on its head has to
(01:30):
do with whether the animal is a predator, meaning it
hunts for other animals to eat, or it's a prey
animal or a vegetarian or herbivore, meaning it eats vegetation
and gets hunted by predators. Let's start for a minute
with your own head. Okay, let's think about your own
head for a second. Your eyes are a predator's eyes,
(01:55):
all right. You have a couple predator things on you.
You have eye teeth or like caninet t pointy teeth. Okay,
that's a predator adaptation. And you have eyes that sit
close together on the front of your head. So as
a predator, what you're pretty good at is you're good
at focusing on something and telling how far away it is. Okay,
(02:17):
that's your specialty. Now let's jump to a rabbit. A
rabbit has eyes, buggy eyes, way out on the side
of its head. Here's the crazy thing about a rabbit.
A rabbit can pretty much see straight behind it. If
you imagine a circle. We describe a circle as a
three hundred and sixty degree loop. Okay, a rabbit can
(02:37):
see most of that three hundred and sixty degree circle
around itself. It can't see directly right behind its skull,
but it can see behind itself okay, because those eyes
that are stuck out to the sides of its head
are looking all around. The right eye is seeing its
own world off to the right, and the left eye
(02:59):
is seeing its own world way off to the left.
The eyes don't do a lot of what we call
binocular vision, meaning the eyes don't work together to aim
and concentrate on a specific item. A rabbit's eyes or
a deer's eyes or a cow's eyes are just surveying
(03:21):
all around them. They need to detect a threat movement, right.
Speaker 2 (03:26):
So if it's a rabbit, he is.
Speaker 3 (03:28):
Looking in an almost complete circle around him while he eats,
while he does.
Speaker 2 (03:33):
Whatever he does.
Speaker 3 (03:33):
If he just sits there and rests, he's looking at
almost a complete circle around him, and his eyes are
really good at picking up on a movement which signifies
the approach of a predator. The rabbit doesn't need to
stare at the predator. The rabbit doesn't need to tell
exactly how far away the predator is. He just needs
(03:54):
to know it's there and what direction is so he
can run the other way. He's a prey animal, and
he's watching out for predators let's jump to a predator's
eyes for a minute. How they sit really close together.
So let's jump to say the fox. And if you
kind of want to understand the eye placement on a fox,
(04:16):
if you have a pet dog, very very similar, they're
both canines. Your dog's eyes are really close together on
his head. Now, your dog has okay, peripheral vision, like
he can see off to the side pretty good, right,
But his specialty is is that he can use both
of his closely placed eyes to focus on something. And
(04:39):
you'll notice if you watch a dog or watch a
cat and they're watching something moving around, both of their
eyes are moving to track its motion. They're using binocular vision,
meeting their eyes are working together. What that does is
that gives you something called depth perception. Okay, so let's
jump to a cat.
Speaker 2 (05:00):
For instance, a.
Speaker 3 (05:00):
Cat is watching a mouse go across the floor. He's
watching it with both of those eyes. He's using his
binocular vision, which is giving the cat death perception, meaning
that cat, by using both of its eyes, knows that
when it jumps, it knows exactly how far away that
mouse is. Because it's using both of his eyes to
(05:23):
look at it, it knows exactly how far that mouse
is and he's going to jump on it and grab it.
So that explains a little bit about why your eyes
are positioned where they are, or why an animal's eyes
are positioned where they are on its head. But let's
talk for one quick second about their pupils. Now, if
(05:44):
you look in the mirror at your own eye, your
pupil is the dark spot in the center of your eye.
Your pupil could be brown, it could be blue, maybe
you have green eyes.
Speaker 2 (05:55):
Whatever it is, that's the pupil.
Speaker 3 (05:56):
That circle thing. It's a circle on you, a human,
But on a lot of predators and prey, the pupils
have a different shape. They're like a long slit. They're
kind of like a bar. Okay, now, on a lot
of prey animals. Like if you go look at a
let's say a horse or goat, you go look at
(06:17):
its pupil. Its pupil is horizontal, so it's like a
flat bar that runs horizontally. If you look at a cat,
its pupil is a vertical bar that runs up and down.
This is another way that the structure of the eye
helps you do what your main job is. That horizontal
pupil is meant for looking way around in a circle,
(06:40):
all around you. It's meant to have really good peripheral vision.
And what's crazy is if you watch, like let's say
you're watching a horse and he's got that slit pupil,
that horizontal bar pupil. When a horse drops his head
down to eat grass, his eyes are not staring at
(07:00):
the ground. His eyes roll almost like roll back into
the back of his head so that that horizontal bar
stays horizontal, so he's always scanning. So even when his
head's down eating grass, he's scanning all around him for predators.
These other animals with the vertical slid are animals sometimes
(07:22):
that hunt at night, so that vertical slit is good
for gathering light, and it also seems to be really
good for determining distance and depth perception. Again, because he's
focusing on something he wants to jump on and kill,
and that eye, that shape of that pupil and where
his eyes sit on his head allows him to focus
(07:43):
on it and know how far away it is. So
then when it makes its attack, when it makes its leap,
it's very accurate. So here's the thing you can do
as you drive around with your parents, or you walk
around or whatever. You you look at different pets you
might have, or you go and you're at a farm
(08:03):
and you look at different farm animals. Take a look
at their eyes and think about where those eyes are
placed on their head. And take a look at their
pupils and see how their pupils are shaped, and see
if what I'm telling you makes sense. There are exceptions
to these rules I'm giving you, so you might catch
me where you think I was wrong, because there are
some exceptions. But what I'm telling you is generally true.
(08:27):
Predators have eyes in the front of their head that
are close together. Prey animals have eyes off the side
of their head that are spread away out, and they
look kind of buggy. They're kind of sticking out so
they can see all around them real good. So pay
attention out there when you're looking at animals, and you
tell me if I seem like I'm kind of right
(08:47):
or if I seem like I'm kind of wrong.
Speaker 2 (08:49):
I think I'm kind of right.
Speaker 4 (08:53):
What's the shark's favorite sandwich? Peanut butter and jellyfish.
Speaker 2 (09:01):
Now it's time for how to make a critter. Call Clay.
Here's going to teach you how to make the sound
of a barred owl.
Speaker 5 (09:14):
Hey, kids, my name is Clay Nukem, and I want
to teach you today about how you can call animals
with your own voice. There are some animals that the
human voice box is really good at mimicking. And today
I want to teach you something that I love to do,
(09:34):
and that is to call barred owls b a rried
barred owls. The bard owl lives in North America and
it typically lived in the eastern deciduous for it's like
the east half of America. But in the last period
of time they've migrated and moved and spread into the
(09:55):
Pacific Northwest all the way up into Alaska. I heard
a bart owl in Alaska the other day. The barred
owl is an incredible animal and it's a raptor. It's
a predator. It catches mice and small mammals. And to me,
the most unique thing about it is that they are
almost completely nocturnal, which means they only come out and
(10:17):
hunt at night. That's primarily when they're out and when
they hunt, and they have incredible vision. But here it
is when they fly, they don't make a sound. The
tips of their feathers are built in such a way
that when it flows across the air, it doesn't make
a noise. I think that's really cool. But the barred
(10:38):
owl is very vocal. They make noises all the time.
And my dad taught me how to barred out hoot.
And there's a phrase that we can use that will
help us remember the sequence and cadence of the noise,
and it's this, who cooks for you? Who cooks for
you all? Say that with me, say who cooks for you?
(10:59):
Who cooks for you all? And so we're going to
replace each of those words with a hoot. And you
make a hoot by making your lips into kind of
an o shape and from deep down in your chest
go So you make the barred al call by connecting
(11:21):
hoots into that specific sequence and cadence of who cooks
for you? Who cooks for you all? And it sounds
something like this, who cooks for you? Who cooks for
you all? I want you to try it. Now, try that.
(11:47):
And the reason that I like the barred ourt hoot
is that if you're a turkey hunter, we use the
barred our hoot to locate turkeys, which is kind of wild.
But a male turkey will gobble at the sound of
a bard ol hooting, and we call it a shock gobble.
It's almost like they're shocks that they hurt an owl,
(12:08):
and so they.
Speaker 2 (12:10):
They gobble.
Speaker 5 (12:11):
And so that's the reason a bart our hoot is
really important to a turkey hunter, and it's important to
a lot of people that like to hunt. Let's try
it again one last time, the barred ol hoot. Who
cooks for you? Who cooks for you all?
Speaker 6 (12:37):
How did the bear feel after he ate the comedian?
He felt funny.
Speaker 2 (12:46):
It's time for everyone's favorite game show, Trivia. Let's all
join in.
Speaker 7 (12:54):
I'm joined by Mabel, Matthew, Rosie, Hayden, Conley, Sage, Hattie,
and Bay. Each play, we learn ten dollars for conservation
with every question they get right. Today, there's a potential
for this room to earn up to two hundred and
forty dollars this week. That donation is going to the
National Wild Turkey Federation, which publishes the kids magazine about
(13:14):
wildlife conservation called Jake's Country. Let's see how much money
our players can raise. Question one, What object in the
night sky is known as ursa major? Is it the
north Star, the Big Dipper or full moon? What object
in the night sky is known as ursa major? Is
(13:38):
it north Star, Big Dipper or full moon? Last week
our players were very confident. They declared the questions were
too easy, but this one may have stumped them.
Speaker 8 (13:54):
Your three choices.
Speaker 7 (13:55):
Your three choices are north Star, Big Dipper or full moon.
One of those things is called ursa major. Not so cocky, now,
are we?
Speaker 6 (14:08):
Kids? It is?
Speaker 7 (14:11):
Everybody ready?
Speaker 8 (14:12):
Yes, go ahead and reveal your answers.
Speaker 6 (14:15):
Bee north Star.
Speaker 7 (14:17):
Rosie, Mabel Star, Hattie, Hayden, Big Dipper, Sage, Conley, Matthew.
The correct answer.
Speaker 8 (14:31):
Is the Big Dipper.
Speaker 7 (14:33):
About half of you got that right. Major is Latin
for great bear or big bear. And although most look
at the constellation and see a ladle for scooping water,
the Greeks and Native Americans saw a large bear, while
the Egyptians saw an ox pulling a plow. So if
ursa major is the Big Dipper, then what do you
(14:54):
guys think the name for the little Dipper is?
Speaker 4 (14:57):
There?
Speaker 6 (14:57):
You go?
Speaker 7 (14:58):
You got it, Hayden, Ursa minor is.
Speaker 6 (15:00):
The Little Dipper?
Speaker 7 (15:03):
Question two? What's it called when an animal regrows a
body part? Photosynthesis? Regeneration or fermentation. What's it called when
an animal regrows a body part? Photosynthesis, regeneration or fermentation.
(15:26):
You got this one right, Matthew.
Speaker 6 (15:28):
No embarrassing?
Speaker 8 (15:33):
And why would it be so embarrassing?
Speaker 6 (15:36):
Well, because we talk about like things like growing stuff along.
Speaker 7 (15:40):
And like Mabel.
Speaker 8 (15:42):
How do you feel about your answer?
Speaker 6 (15:44):
I'm pretty pretty happy with it, just because I don't know.
Speaker 7 (15:47):
Okay, Sage, you're not You're not real kind.
Speaker 6 (15:49):
I wouldn't be surprised if I didn't get it right.
Speaker 7 (15:51):
I know what's it called when an animal regrows a
body part? Photosynthesis, regeneration or fermentation. What do you got Conley?
Speaker 6 (16:00):
I know it's them.
Speaker 7 (16:01):
Okay, you've narrowed it down to two of the three.
Everybody ready, yes, yeah, and reveal your answers.
Speaker 4 (16:10):
Bay regeneration, Rosy, Mabel regeneration, Hattie regeneration, Hayden regeneration, Sage regeneration.
Speaker 7 (16:20):
Conley, Matthew, the correct answer is regeneration.
Speaker 8 (16:28):
Room did pretty well. Moto Synthesis is.
Speaker 7 (16:33):
When plants turn the carbon dioxide into oxygen. Fermentation is
the chemical breakdown of a substance, and regeneration is the
process of replacing damaged cells. Tissues or organs. Some animals
with regeneration are salamanders who can regrow their tail, starfish
who can regrow their arms, and axi lotels who can
regrow their legs.
Speaker 2 (16:55):
You love them.
Speaker 7 (16:55):
Now, if you could grow an extra leg or an
extra arm, which would you pick? What do you do
with the extra leg, Matthew, Well.
Speaker 4 (17:07):
If I regroded my leg, I think it'd be more helpful,
more help because I could just I could just get.
Speaker 6 (17:13):
Up one of those robots.
Speaker 7 (17:15):
You're gonna need some extra shoes and make you right
to an extra Yeah. Now this side of the room
wanted an extra arm.
Speaker 6 (17:22):
No, I want an extra brain because you could grab
more stuff at the same time.
Speaker 4 (17:25):
Yeah, scare people, But like extra toe is just cool,
like because like you could be like I actually have
eleven toes, Like, well, everybody else has ten, I have eleven.
Speaker 8 (17:39):
I can't debate that that's the same.
Speaker 6 (17:41):
As like an arm, you have two arms. I have three? Yeah.
Speaker 7 (17:44):
I question three. Which of these states does not touch
the Mississippi River? Is it Missouri, Mississippi or New York?
Which of these states does not touch the Mississippi River Missouri,
(18:05):
Mississippi or New York Okay, but you.
Speaker 6 (18:10):
Guys realized that it could actually be what you guys
are thinking.
Speaker 4 (18:13):
It's not.
Speaker 6 (18:13):
Wow, New York is all the way like the top
of the USA.
Speaker 4 (18:16):
I know I'm not saying saying that the Missouri River
is in New York. What I'm saying is you think
I tried to trick.
Speaker 7 (18:27):
Yeah, Okay, is everybody ready which of the states does
not touch the Mississippi? Is it Missouri, Mississippi or New York?
Speaker 8 (18:37):
Go ahead and reveal your answers.
Speaker 7 (18:39):
Babe, New York, Rosie, New York, Mabel, New York, Hattie,
New York, Hayden, New York, Sage, New York, Conley, New York, Matthew,
New York.
Speaker 8 (18:49):
Everybody got it right. The correct answer was New York.
Speaker 7 (18:53):
New York is about six hundred miles away from the
Mississippi River. Besides Missouri and Mississippi, the river flow was
through eight other states. So here's what we're going to do.
For every state you guys can name that touches the
Mississippi River, We're going to add an extra ten dollars
to the donation. But it's three strikes and you're out.
(19:13):
So everybody talk it over about what states you think
could be, and then Mabel will deliver the final answer.
Speaker 6 (19:20):
Mississippi, Mississippi, Missouri.
Speaker 8 (19:24):
So you know Mississippi and Missouri. There are eight other states,
both of the Dakotas.
Speaker 7 (19:33):
Maybe what do you think it is?
Speaker 6 (19:34):
Think I'm gonna go as North Dakota. It's oh my god,
how do you know? You don't know that.
Speaker 7 (19:44):
North Dakota is not one of the states. Give us,
give us a second.
Speaker 6 (19:53):
Stick, second stake.
Speaker 4 (19:56):
Oh gosh, Okay, Matthew is pretty confident Minnesota.
Speaker 6 (20:03):
Do you trust him? Yes, I don't trust. I don't
really don't trust.
Speaker 5 (20:09):
Trust.
Speaker 6 (20:11):
It's no no trust me. I swear it's right, it's right.
Speaker 7 (20:20):
The good news is if Matthew is wrong, you can
He'll hear about it for the rest of his life.
Speaker 8 (20:25):
So but if he's right, you guys add ten.
Speaker 6 (20:27):
Dollars for trusting. You don't have to do it.
Speaker 4 (20:32):
But I'm just saying you could because I think nobody
else is giving me any help and I have matt yet, Like,
why do you don't know?
Speaker 7 (20:39):
But okay, okay, Minnesota, Minnesota.
Speaker 8 (20:43):
What it's correct? That is one of them.
Speaker 7 (20:48):
That means there are seven more states to go or
two strikes. Mabel, do you want to give us another stake?
Speaker 6 (20:55):
And I don't really want it, but I don't know.
Speaker 7 (20:58):
Do you want to give the responsibility to someone else?
Speaker 6 (21:00):
Sure?
Speaker 7 (21:00):
Yeah, has responsibility. Give me a stay at Addie. You
have one strike and seven states to go.
Speaker 6 (21:08):
This is kind of scary. I know it is all
all trust.
Speaker 8 (21:12):
Stage Kentucky.
Speaker 7 (21:14):
Kentucky is correct, you guys, states and one strike? Who
else wants to give us an answer? Hayden, do you
want to be in charge.
Speaker 8 (21:23):
Of the next day? Rosie would like to be in
charge in the church.
Speaker 7 (21:28):
Now, do you guys have any input for Rosie on
what the next states?
Speaker 6 (21:33):
I think maybe the Virginia's is Alabama? Touching? Yes, take Alabama?
I agree with Mabel.
Speaker 4 (21:39):
Alabama Alaba Alabama.
Speaker 8 (21:44):
Alabama is incorrect. You guys have.
Speaker 7 (21:54):
And six states to go. You're gonna be in charge
of the next one. Do you guys have any input
for Stage on the next Hio?
Speaker 6 (22:02):
No, don't do a high up Ohio. Don't wait? Wait
wait wait, maybe maybe like Georgia. Wait done? Montana?
Speaker 8 (22:10):
No, okay, Sage, give us a state.
Speaker 7 (22:15):
Virginia is incorrect, that is your strike.
Speaker 8 (22:22):
Idaho is incorrect.
Speaker 7 (22:25):
Back the other six The other six states are Wisconsin, Iowa, Illinois, Tennessee, Arkansas,
and Louisiana. But the good news is you guys added
an extra twenty dollars to the end, so fill the engineer.
How much money did we raise.
Speaker 8 (22:41):
With that additional twenty dollars? They raised a total of
one hundred eighty dollars, one.
Speaker 7 (22:45):
Hundred eighty dollars going to the National Wild Turkey Federation.
Speaker 8 (22:50):
Well done, kids. Join us next week for more Meat
Eater Kids.
Speaker 7 (22:54):
Trivia, the only other game show where Conservations always wins.
Speaker 2 (23:00):
Thanks for listening to everyone, See you next week on
Meat Eater Kids.
