adapted to their habitat?
Penguins bodies and behaviour
have changed a lot so that they
can cope with the cold and with life
next to the sea

4. Penguins are designed for life in the sea
Penguins are designed for life in the sea. Some species spend as much as three-quarters of their lives in the water. (They lay their eggs and to raise their chicks on land.)
Heavy, solid bones act like a diver's weight belt, allowing them to stay underwater.
Their wings, shaped like flippers, help them "fly" underwater at speeds up to 15 mph.
A streamlined body, paddle-like feet, insulating blubber, and watertight feathers all make them good at swimming underwater.

5. How do penguins keep warm?
Penguins spend a lot of time dealing with temperature.  They are warm blooded, just like people with a normal body temperature of about 37 degrees C.   
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.

6. Huddle together
Penguins often need help to stay warm.  In photos and video, you'll often see groups of penguins huddled shoulder to shoulder with their wings tight against their body keeping each other warm.  As many as 5,000 penguins will bunch together to warm each other up. They take turns to be on the outside in the cold wind

Label it to show how its body is adapted so that it can cope
with the cold and swim really well
