How do penguins cope in the cold?

Answer 1

• Air is a good insulator and so it will trap the body heat of the penguins. It also makes the whole group of penguins warmer and the product of all the penguin's body heat is greater that of just one penguin other than that, they will also rotate around with the penguins on the outside.

Answer 2

Penguins have a thick layer of fat underneath the skin which helps to store energy. This thick layer of fat also insulates them. Penguin feathers are also specially designed. They are short and have an under-layer of fine woolly down, and easily shed water - a useful characteristic given that penguins spend up to 75% of their time in the water. Penguin feathers are shaped to overlap, enabling better streamlining for penguins when they are in the water, and protection from the wind when they are on land.

Answer 3

Emperor Penguin males huddle together in order to keep as much bodily warmth among them as possible. This behaviour precedes hatching: the males balance the unhatched eggs on the tops of their webbed feet and cover it with a fat-filled and warm belly flap. Their circulation is just warm enough to keep their webbed feet blood from freezing.

This behaviour takes place in August, the coldest time of year in Antarctica's beaches where they breed.

Once the chicks hatch, the males turn them over to the returning females -- that have ventured across the ice to open water to feed after laying the egg -- and make their way to open water to feed as well. The hatching period can be up to about six weeks.

The females feed the chicks by regurgitating food from their stomachs until the sea ice thaws enough for them to forage in open water for food. Once the chick's down has molted off their bodies, they fledge and can go into open water and feed themselves.

Answer 4

they all huddle together to keep themselves warm.
