The shells that hermit crabs seek are made by marine gastropods that secrete calcium carbonate from their mantelthe organ that covers their soft bodies. The shell is built up in deposits until the calcium carbonate becomes a crystalline structure held together via thin membranes of organic material.
Do hermit crabs grow their own shells?
Hermit crabs are omnivorous scavengers, eating microscopic mussels and clams, bits of dead animals, and macroalgae.

Can hermit crabs be bred?
While breeding hermit crabs can be a challenging experience, it is possible to breed them if you pay close attention to their behavior and habitat. Once hermit crab young have chosen shells and have begun to travel on land, their chance of survival increases greatly.
Are hermit crabs asexual?

What do baby hermit crabs need?
It needs to be salt water? Key to survival: pet hermit crabs need a bowl of fresh water and a bowl of ocean salt (not table salt) water in their cage at all times. Hermit crabs use the water to drink, bathe and replenish the extra water they carry within the back of their shells).
How long does it take for a crab to grow full size?

How do baby hermit crabs find a shell?
Sometimes hermit crabs that live together help each other find new shells. When a new, large shell becomes available, hermit crabs have been known to form a line by it from largest to smallest. The largest crab moves into the new shell. The next largest crab moves into the shell just vacated by the last crab and so on.
Where do hermit crabs find their shells?

How do hermit crabs pick their shells?
It is clear that hermit crabs do not enter shells at random, but select shells according to shape, shell opening and weight. A variety of mechanisms such as shell rapping, olefactory signals, and visual ques have been shown to transfer information about the quality of a shell.
How do crabs get new shells?
Just as we outgrow our clothing, crabs outgrow their shells. Prior to molting, a crab reabsorbs some of the calcium carbonate from the old exoskeleton, then secretes enzymes to separate the old shell from the underlying skin (or epidermis). Then, the epidermis secretes a new, soft, paper-like shell beneath the old one.
What does hermit crab babies look like?
