Question

Penguins can't fly but still have streamlined body why

Answer 1

this is because they swim in water.Their streamline body makes them ideal to swim underwater.Penguins cannot fly in air but it can be said they fly through water

Answer 2

Hey,here is the answer to ur question.......!!
In a sense they really do fly ,only through the water ,not through the air . Penguins have Strong wings and strong pectoral muscles to poWer them. Their bodies are streamlined as if for flight ,so they still cut cleanly through the water. But water is much thicker than air ,so their wings are shorter and stiffer than a normal birds wings .In fact penguins are the only Birds that are unable to fold their wings .Their wing bones are fused straight ,making the wing rigid and powerful like a flipper......
Hope this helps u.....!!!
