a flying pig
Humans. We don't have wings, but we build airplanes and helicopters.
i dunno the one without wings but i know that the one with wings is a bat! A flying squirrel is a mammal without wings.
The bat, which is also the only mammal with wings.
A platypus does not have wings. It is a mammal, not a bird, and bats are the only mammals that can truly fly.
Human beings. We have no wings, so we use airplanes to fly around.
Bat is the mammal that can only fly.
The only mammal that can fly is the bat.
Because feathers are not needed to fly. Wings are required, and that they do possess. Feathers are mostly meant to keep it warm or heat insulation.
yes. Birds are the only animals on earth that have feathers covering their bodies. They are also a vertebrae animal, which means they have a spine.
Man is the only mammal that cannot fly but does. He uses aeroplanes. (And the penguin is not a mammal: it is a bird and some say it 'flies' underwater.)
