Friday Fun: Five Gross and Goofy Body Facts

1. A polar bear has white fur, but its skin is black. Dark colors soak up heat from the sun more quickly than light colors, so black skin helps a polar bear stay warm in its chilly Arctic home.

 2. When an anole lizard rests on a leaf, its green skin makes it hard to spot. But when the little lizard moves onto a tree trunk, its skin slowly darkens to match its new surroundings.

3. Frogs and salamanders can breathe through their thin skin.

4. Some frogs shed their skin every week. They stretch out their old skin and pull it over their head. Then they eat it. Mmmm! Delicious!

5. A snake outgrows its skin three or four times a year. When the old outer covering splits open, the snake crawls forward. Its skin peels off in one long piece.

  1. I love the image of a frog pulling its skin over its head like a sweater. Eating it is the icing on the cake!
