A healthy crab generally shed it's skin, or molts every 18 months. This varies, depending on it's size. Smaller crabs, tend to molt more often.

Does the hermit crab shed its shell of its claws legs ect?

A hermit crab grows out of it's shell and looks for a new discarded snail's shell. Snails produce the shells and once the snails die the shells become homes for hermit crabs. Hermit crabs molt their exoskeleton Large Jumbo crabs molt about once a month and smaller crabs molt a few times a month. They collect water and food into their shell and burrow deep into the sand where they shed their old skeleton and eat it. They eat their old skeleton to regain nutrients that they lost during the molting process. If a hermit crab looses it's legs (which doesn't usually happen during the molting process) they will regenerate.

Do saltwater hermit crabs molt?

Hermit Crabs do shed there skin (when they molt) - which is when you have to pay VERY close attention. You can tell when they're molting because they eat extra, dig holes alot more and sleep most of the day and night.-------------------------------------------------------------------------------------------------Hermit Crabs look like they die and fell out of thier shell. The skin they left behind looks just like them but they only grew out of thier old skin and are still growing like a snake, cicada, or anything else that sheds and leaves skin or a shell behind. So don't worry. I found one my first time having one. It looked like it was transfering into a new shell. It was in there for a while so when i picked it up the skin fell off and when i thought it died I almost threw the shell away but I looked in the shell and the crab was in the shell still. So thats when i looked up this question. When hermit crabs actually die they look like a shrimp with their tail but when they molt they don't shed all the way to their tail, only half way. HOPE THIS HELPED.

Do hermit crabs act dead when they are molting?

Yes. When a hermit crab is molting, it reserves energy by not moving. The old skin will be shed and look like a ghost crab. Make sure that your hermit crab has plenty of water in it's dish or sponge as humidity is a great help to him or her during this process.
