The Glass Frog Isn’t Made of Glass But That Would Be Pretty Cool

[Narrator] Oh, hello little frog!

Hate to embarrass you like this,

but your insides are showing.

You're okay with that?

Alright then.

I guess that's why they call you the glass frog.

You can find over 150 species of glass frogs

in the rainforests of Central and South America.

It's so translucent that you can even see its beating heart.

And it's not just the stomach that's see-through.

If you look hard enough, you can even

see through some species' legs and glimpse their bones.

And here we see the special adult time of the glass frog.

As well as the eggs inside the female's belly.

So why the transparency?

The truth is, scientists aren't really sure.

It could play some part in camouflage.

Regardless, the glass frog's green coloration

definitely helps it blend in.

And check out these eyes.

Kind of weirdly, for a frog, they point straight ahead,

as opposed to sitting on the sides of the face.

That might help the glass frog target prey, like insects,

right in front of it.

So there you have it.

The glass frog, the rainforest's greatest advocate

for transparency.

Though, not necessarily invisibility.
