Häutungsprozess

Häutungsprozess refers to the shedding of an outer layer, most commonly associated with animals possessing an exoskeleton or specialized skin. This process is crucial for growth and repair in many species.

For arthropods like insects, spiders, and crustaceans, the exoskeleton, also known as the cuticle, does not grow. To increase in size, they must periodically shed this rigid outer layer and replace it with a new, larger one. The old cuticle is typically split open, and the animal emerges. It then inflates its new, soft exoskeleton with body fluids and air, allowing it to expand before it hardens. This vulnerable period after molting is known as the ecdysis.

Reptiles, such as snakes and lizards, also undergo a form of shedding, though it is less about growth and more about replacing damaged or worn skin. Snakes often shed their skin in one piece, a process that can take several days. Lizards may shed in patches. This shedding mechanism helps them to remove parasites and allows for continued skin health.

Amphibians, particularly salamanders, also shed their skin, though the frequency and manner can vary greatly among species. The removed skin is often consumed by the animal. The shedding process in these animals is often linked to environmental conditions and their life stage.
