What happens if a hermit crab is too big for its shell?

When a hermit crab spots a new shell, it’ll size up the shell for a good fit. If the shell is too big, the prospecting hermit crab will sit back and wait to steal the castoff shell of a larger crab that decides to upgrade. In the meantime, while the first crab waits, other crabs gather around the shell and do the same.

How big can a hermit crab be?

How do you tell if a hermit crab is too big for its shell?

What happens if a hermit crab shell is too big?

If the shell is found to be too large, the crab goes back to its own shell and then waits by the vacant shell for up to 8 hours. As new crabs arrive they also inspect the shell and, if it is too big, wait with the others, forming a group of up to 20 individuals, holding onto each other in a line from the largest to the smallest crab.

Why do hermit crabs have a hard time breathing?

A high humidity level makes it difficult for the hermit crab to breath due to the ‘thicknesses’ of the humidity. If subjected to a too high humidity level, this can promote a gill infection that may cause irreversible damage. Maintaining humidity levels of 90% and higher is discouraged.
