Why do aerial animals have light bodies?​

Answer 1

Answer:

Amphibians have dual life because in water they respire with the help of lungs but on the land they respire with the help of moist skin because this skin contains mucous glands.

e.g, frogs, toads, salamanders etc.

Aerial animals have light bodies because their main function is flight. In their bones the bone marrow is absent hence they have capability to go in the air.

e.g, birds and some insects have potency to travel longer distances in the air.
