What is bat outer covering?

Fur

Bats are the only mammals capable of sustained flight. They have a unique body structure that includes a pair of wings that are made of skin stretched over elongated finger bones. Bats also have a special type of fur that helps them to fly.

Bat fur is very dense and soft. It is composed of two layers: an outer layer of long, guard hairs and an inner layer of short, dense fur. The guard hairs help to protect the bat from the elements, while the inner fur helps to insulate the bat and keep it warm.

Bat fur also plays an important role in flight. The dense fur helps to create drag, which slows the bat down and allows it to control its flight. The fur also helps to create lift, which allows the bat to stay in the air.

In addition to its role in flight, bat fur also helps the bat to camouflage itself. Many bats have fur that is dark in color, which helps them to blend in with the night sky. Other bats have fur that is patterned or variegated, which helps them to hide in foliage.

Bat fur is a complex and important part of bat biology. It plays a vital role in flight, camouflage, and insulation.
