Why do reptiles shed their skin?
The skin of reptiles has a horny surface layer. In lizards and snakes, this horny layer forms a hard, continuous
covering of scales. As the animal grows, this outer layer is shed, allowing for further growth.
Crocodiles, alligators, and some lizards have bony dermal scales covered by a horny epidermal layer,
which must be shed to allow for body growth.
