We're back with another set of amazing
0:04
animal facts. Number 10. Koalas have
0:08
fingerprints. Just like us, even a
0:11
koala's fingerprints are nearly
0:12
indistinguishable from human
0:14
fingerprints. Under a microscope, the
0:15
two look identical. They share the same
0:17
type of fingerprints.
0:19
Scientists say koalas have evolved to
0:21
have similar fingerprints because they
0:23
spend so much time climbing trees.
0:26
It's helpful for gripping branches. No.
0:30
Nine geckos can walk upside down on
0:32
glass. You might think it's magic, but
0:34
it's actually molecular adhesion. The
0:36
tips of their toes are covered with
0:37
millions of tiny hairike structures.
0:40
These hairs enable the gecko to stick to
0:42
surfaces at the molecular level. The
0:44
force of the molecules pulling the gecko
0:46
s toe hairs is greater than the force of
0:48
gravity pulling the gecko downwards.
0:50
ass.
0:51
And since each foot has millions of
0:53
these hairs, geckos can support their
0:55
entire body weight on glass
0:58
number eight. Some fish can change their
1:00
sex. Most people think a fish's sex is
1:04
determined by its genes. However, some
1:07
fish can change their sex if the
1:09
circumstances demand it. Clown fish,
1:13
rasses, and groupers can switch from
1:15
male to female or vice versa. This is
1:18
most common in species that live in
1:20
groups. If the dominant female in a
1:23
group dies, one of the males will change
1:25
sex to replace her. Number seven, snails
1:28
can sleep for up to 3 years. People
1:31
sometimes describe someone who sleeps a
1:33
lot as a slug or snail, but compared to
1:35
a snail, our sleeping habits are insane.
1:38
Snails can go into deep hibernation for
1:40
years. They do this to survive droughts.
1:44
When water is scarce, snails seal
1:46
themselves inside their shells and slow
1:48
their metabolism down to extremely low
1:50
levels. When the drought ends and
1:52
there's enough moisture around, snails
1:54
wake up and get back to their normal
1:56
lives. Number six, the wandering
1:59
albatross has the largest wingspan of
2:02
any bird. These birds can glide for
2:04
hours without flapping their wings.
2:07
Their wingspan can reach up to 12 feet,
2:09
which is 3.6 m. To put that in
2:12
perspective, the average adult giraffe
2:15
is about 14 ft 4.3 m tall. So, a
2:19
wandering albatross could theoretically
2:20
have a wingspan longer than itself.
2:23
No. Five goats have rectangular pupils.
2:26
When you look at a goat, you'll notice
2:28
something unusual about its eyes. Goat
2:31
pupils aren't round like ours. They're
2:32
rectangular. This gives goats a wide
2:34
panoramic view. They can see almost 360°
2:37
around them. This is helpful for
2:39
spotting predators. Imagine if your
2:41
pupil was rectangular. Could see much
2:43
better to the sides of you, but your
2:45
vision would be kind of distorted
2:47
straight ahead. Number four, sharks
2:50
existed before trees. Sharks have been
2:52
around for over 400 million years. Back
2:56
then, the Earth's land masses had little
2:58
vegetation. The first forests wouldn't
3:00
appear for another 350 million years.
3:04
So, sharks have been around for 100
3:06
million years before trees evolved.
3:08
Fact, sharks were around for 50 million
3:10
years before dinosaurs appeared. No.
3:13
Three. Some ants can build living rafts.
3:16
Humans aren't the only creatures capable
3:18
of building rafts. Some parts of the
3:20
world, fire ants build living rafts to
3:22
survive floods.
3:24
When a colony of fire ants is surrounded
3:26
by rising water, they link their bodies
3:28
together. The ants form a circle,
3:30
holding on to each other with their legs
3:32
and abdomen. Then they start to float
3:34
away. Once the water recedes, the ants
3:37
continue to hold on to each other until
3:38
they find dry land. Some of the ants
3:41
will die during the journey, but the
3:43
colony will survive. No, two parrots can
3:46
live longer than humans. Although many
3:48
animals can live longer than humans,
3:50
like tortoises and Greenland sharks,
3:52
parrots are special. Some species of
3:54
parrot can live up to 80 to 100 years
3:56
old. It's longer than the average human
3:58
lifespan. In the wild, parrots usually
4:01
don't live that long. In captivity, they
4:04
can get proper nutrition and health
4:06
care, which extends their lifespan.
4:08
Macaus are among the longest living
4:10
parrots. There are many pet macaw who
4:13
have lived well into their 60s and 70s,
4:15
and no one. Crocodiles can go months
4:18
without eating, and crocodiles bask.
4:20
They're often seen floating on the
4:21
surface of the water with their mouths
4:23
open. This is not only to regulate their
4:25
body temperature, but also to conserve
4:27
energy. Crocodiles can slow their
4:30
metabolism down so much that they can
4:32
survive on just a few meals a year. A
4:34
crocodile can go for months without
4:36
eating. It's not uncommon for a
4:38
crocodile to go 40 days without food.
4:40
That's all for now. Thanks for watching.
