Crayfish shed their shells because they are growing. they do not shed their skin, but rather the inflexible shell on top. Because it is inflexible, it cannot grow with the crayfish and they have to make new ones. Replacing a shell is called "molting". crayfish and other crustaceans molt more when they are young and are growing faster. Hope this helps!
Yes because if they didn't then they wouldn't grow.
Yes, they do. In fact, when they do, it looks like pieces of a whole new crawdad. I know this because there is a crawdad I caught from a stream across my street, and I am watching it shed its skin.
No African Dwarf Frogs do not shed there skin.
They regularly shed their skin its quite irreagular for them to shed skin though..
Yes, as they grow they will molt (shed their skin) a number of times before they pupate. Lar
Corn Snakes? Yes, all snakes shed their old skin.
After molting their exoskeleton, crayfish are a deep red colour. Some may be lighter than others.

No, eels do not shed their skin like a snake

Geckos shed old skin because it get old and dry and so they can grow bigger, we shed our skin to it takes a whole year to shed the whole of it but we do shed too :)
As snakes grow the skin doesn't grow with them, so they shed the skin because it no longer "fits" them. By shedding the skin they can get larger, and grow.
ALL snakes (and lizards) shed their skin periodically. The general rule is - the younger the reptile - the more frequently they shed. Reptile skin is regenerated all at once - not in tiny flakes like human skin. Thus they have to shed their skin in order to grow.
