Temperature
Penguins spend a lot of time dealing with
temperature. They are warm blooded, just like people with a normal
body temperature of about 100 degrees F.
So how do they stay warm in the cold
places they live and in the icy cold waters?
Just like whales,
penguins have a layer of fat under their skin called
"blubber". Overtop of this they are covered with fluffy
"down" feathers and overtop of those they have their outer
feathers which overlap to seal in warmth. Penguins rub oil from a
gland onto their feathers to help make them waterproof and windproof.
