Sunday Sketch: Flying Mammals

Did you know?

Bats are the only mammals that can fly! Other “flying” mammals like sugar gliders, flying squirrels, and colugos cannot truly fly: they can only glide for short distances. Bats, however, are capable of powered flight for long durations.

For more information on the evolution of bat flight:
