Medium ones about the size of a golf ball may molt every four to six months and stay buried for about one to three months. The smaller hermit crabs may molt as often every month or even every few weeks for the tiniest ones, and may stay buried to do it for only a couple of weeks or months.
This enables the crab to orient the shell maintain its position within the shell. When a hermit crab outgrows its current shell, it will select a new one to inhabit. Long-clawed hermit crabs live mostly in shallow water and are common in tide pools and salt marshes. Broad-clawed hermit crabs live in deeper waters. Hermit crabs are active animals, moving about in search of food.
