Understand the principle of echolocation 1. Bats have many special features.
Bats are the only mammals that can fly, therefore wings are obviously a special feature.
The bat is able to adjust its wings in flight. While many animals like bears hibernate to save energy in winter bats go into a state of 2 time torpor usually starts at dawn and ends at dusk.

Bats that roost alone get greater benefits from torpidity since they can drop their temperature more. 5 temperature.
