Like many invertebrates, reptiles and amphibians periodically shed a layer of their skin all at once (this differs from humans and other mammals, which continuously shed individual skin cells). This process is called ecdysis, sloughing, or molting. Ecdysis is a function of growth, and, as such, it occurs more frequently in younger or well-fed individuals. Ecdysis may also occur in response to illness or irritations, such as a skin infection or parasite infestation. Many animals ingest the shed skin, partially to retain nutrients and partially because pulling at the loose skin with their mouths aids in removal.
