I just love their little bony knees.
Joey with both knees bent and feet tucked under his tail.
Bats are the only mammals whose knees bend backward, and not forward, and the bottom of the feet face forward.
Joey flat-out and fast asleep.
Left knee bent, toes tucked under. Right knee bent, leg stretched with foot flat.
Bats toes have little claws that enable them to hang upside down with ease.
Clever little batties.
