What is a bat wing?

AnimalsAnatomy

Quick Answer

A bat wing is a modified mammalian forelimb stretched by a thin skin membrane called the patagium. It is built from the same basic bones as a human arm and hand.

The Full Story

Bat wings are not feathers or separate structures; they are highly modified hands. The long finger bones support the wing membrane, which extends between the fingers and often to the body and legs. This design gives bats remarkable control and maneuverability in flight. The bat wing is a striking example of how mammalian limbs can evolve for a completely different function.
