Remember when you were a teenager
and you would wake up with those bad hair days?
Just like us, king penguin adolescents
also have the same problem.
Before they get to looking slick and dressed to impress,
adolescent king penguins have to go through puberty.
And boy, is it uncomfortable.
They're covered in big, fluffy brown feathers,
so when they come out of the water they look like they
were dragged through a puddle.
Kinda cute.
But this stage of their lives is crucial.
Their feathers help them become waterproof
and stay warm
as their layers of blubber grow underneath.
So until their adult black and white coats grow out,
they look like slouched, annoyed teenagers.
If you thought that was embarrassing,
there are many more animals in line for the king penguin's
awkward puberty throne.
We're taking a look at some of the animal kingdom's
biggest teenage-like tantrums.
Get ready for more bad hairdos and
growth spurts, one leg at a time.
It's not just physical changes that are apparent
when we go through puberty.
There are also behavioral changes.
Human teenagers are known for being moody and emo.
In the animal kingdom,
the gorilla might be the moodiest of them all.
Teenage gorillas go through the same problems
that affect us at the same age.
Females start their hormonal shift
and menstrual cycle at this time.
And once they reach adulthood,
they will leave the family group and look for a partner.
Some females are even picky about who they choose,
trying several different males
before settling down with their mate.
You go girl.
Males become more aggressive
and will pick fights with each other
to show their dominance,
acting big and tough to prove themselves
in their social groups.
It sounds like the movie Mean Girls.
Now I bet you didn't think chickens
would be on this list, did you?
Unintentionally standing out from the crowd,
they have the same problem as the penguins
with shabby-looking feathers.
Try as they might to blend in with the adults,
they just don't cut it.
Also the males start getting feisty
and sometimes having brutal fights.
While the females wil start laying eggs,
they won't be as high quality until they reach adulthood.
It's just not easy for these creatures it it?
Sticking with birds,
the magnificent birds of paradise are stunners.
But you might notice in some of the species
a big difference between the males and females.
The plain birds are females
and the extravagant ones are the males.
In some species, they look like absolute
divas.
I love it.
This is known as sexual dimorphism
and it comes about from males
competing to be the most attractive to the females.
This means ornate plumage, loud mating calls
and well choreographed
dances.
And last on the list with probably the most drastic
physical change are frogs.
It's no secret they start off as eggs
that develop into tadpoles,
but have you seen the in-between stage
of a tadpole transforming into a frog?
They are literally half tadpole, half frog,
and it looks kinda weird.
The change comes about from the production of a hormone
in the thyroid gland.
The back legs grow out first,
with the tadpole tail stuck between them.
It's also the time when the internal organs develop,
so the maturing frog can live both in and out of the water.
While these animals might have to go through some
uncomfortable stages during puberty,
there are others that are literally dying to mate
once they're all grown up.
We have the reasons why in another episode.
They go through puberty with all the same social
and physical baggage as we do.
And that's what makes these brooding animals
Crazy Creatures.
