Penguins have to keep high body temperatures to remain active. They have thick skin and lots of fat (blubber) under their skin to keep warm in cold weather.
They also huddle together with their friends to keep warm. Emperor penguins have developed a social behaviour that when it gets cold, they huddle together in groups that may comprise several thousand penguins.
Penguins have webbed feet for powerful swimming. Their bodies are streamlined to reduce drag in water. Their wings, shaped like flippers, also help them swim underwater at speeds up to 15mph.
Penguins tightly packed feathers overlap to provide waterproofing and warmth.
Waterproofing is critical to penguins' survival in water, Antarctic seas may be as cold as -2.2°C and rarely get above +2°C. (-2°C is the freezing point of sea water).
