Caenorhabditis elegans, a nematode worm and one of the most-studied organisms in the lab. c. elegans moves through four larval stages, molting after each one.. Since the shell is hard, it must be removed from time to time as the animal's body grows naturally to allow room for the larger body. in the case of snakes, who don't have a hard outer shell, they shed their skin because it doesn't grow with them like human skin. therefore, as the snake grows, he must shed his outer skin in order to grow new skin.. Why snakes shed their skin. basically, a snake will shed its skin to allow for continued growth. the skin of a snake is different from the skin of a mammal (including us) in that it does not grow as the animal grows..
The most familiar example of moulting in reptiles is when snakes "shed their skin". this is usually achieved by the snake rubbing its head against a hard object, such as a rock (or between two rocks) or piece of wood, causing the already stretched skin to split. at this point, the snake continues to rub its skin on objects, causing the end. They shed their skin because their skin is really their exoskeleton and it never gets bigger. if an insect outgrows its exoskeleton then it has to get rid of it and grow a new bigger one. not all arthropods do this:hermits crabs use the shells of other animals for instance.. How do spiders shed their skin? this is a video explaining how spiders shed their exoskeletons, during the molting process. also a compilation of footage of my pet african red trapdoor spider and.
