Question:
How come penguins can't fly? Why do they have wings?


Replies:
Penguins are birds so having wings in no surprise. However, even though penguins have lost their ability to fly in air, their wings are now adapted to "fly" in water. The ocean is where their food is found. Their bodies have evolved to move easily through water and their wings are used as rudders and propellers. Being adapted to water and insulated from cold environments, their bodies are now too heavy to fly in air. They are the only bird to survive in extreme cold for long periods of time.

Hi Danielle

The penguins cannot fly because their wings are not adapted for it.Instead of all the birds they are the most fully adapted to swim and to stay in water and in the extreme cold. As you say they are flightless and clumsy when walking in land but are at home in the water. They come to land to breed, to lay their eggs and to have their young. Actually they are a beautiful example of species adaptation. Thanks for asking NEWTON

Penguin wings have become adapted for swimming. They use their wings to "fly underwater" much as other animals use flippers or fins.

Penguins cannot fly because they are so heavy!! Birds that can fly have very special bones, ones that are hollow like a straw. This makes them very light so they can fly. Penguins do not have hollow bones, there is no hole in the center, so they are much to heavy to fly. Even though they cannot fly, they are better at swimming underwater than most birds!
