The adaptions of a penguin
Cards in this deck (5)
- 1How are penguins adapted so they can swim fast?Penguins have webbed feet for powerful swimming. Their bodies are streamlined to reduce drag in water. Their wings, shaped like flippers, also help them "fly" underwater at speeds up to 15 mph.
- 2How do penguins keep warm?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.
- 3Why do penguins have dark coloured feathers?The dark coloured feathers of a penguin's back surface absorb heat from the sun, so helping them to warm up too.
- 4What is the job of penguins feathers?Penguins tightly packed feathers overlap to provide waterproofing and warmth. They coat their feathers with oil from a gland near the tail to increase impermeability. Waterproofing is critical to penguins' survival in water, Antarctic seas may be as cold as -2.2°C (28°F) and rarely get above +2°C (35.6°F).
- 5How do penguins stay under water?Penguins don't have all the extra airspaces in their bones that normal birds have. Their heavy, solid bones act like a diver's weight belt, allowing them to stay underwater.
