A chameleon can change the color of its skin.

It changes color to hide, to warm up, or to show how it feels. Special color cells in its skin do the trick.

The sea otter has the thickest fur of any animal.

An otter can have hundreds of thousands of hairs in one small patch. All that fur keeps it warm in cold water.

Sheep grow wool that keeps them warm, and it keeps growing.

Farmers give sheep a haircut called shearing. The wool grows back, a bit like your hair does.

A turtle's shell is part of its body and can feel a touch.

The shell is joined to the turtle's backbone and ribs. A turtle can never crawl out of its shell.

Birds fluff up their feathers to stay warm on cold days.

Fluffing traps warm air next to the body, like a cozy jacket. Feathers also help birds fly.

A pangolin is covered in scales made of the same stuff as your nails.

When it feels shy, a pangolin rolls into a ball. Its hard scales act like armor to keep it safe.

A polar bear's fur isn't really white — it's clear!

Each hair is see-through and hollow. The fur only looks white because it reflects the bright snow around it.
