Penguins vs.
Tubenoses.
How well do they fly and swim? |
|
Definition
Tubenoses can fly long distances but do not swim. Penguins are flightless and swim very well
· Tubenoses are great flyers and have very large wingspans. They fly over great distances to forage for food. They stay months out at sea catching fish on the surface. They are great gliders, and they expend as little energy as possible. Albatross are the best examples of tubenoses. |
