Pagurus Bernhardus hermit crabs change their shells

Watch related videos from these video collections:

When a common marine hermit crab (Pagurus bernhardus) grows, it starts to look for slightly larger shells that it can live in. We know that it wants to carry around something more comfortable and appropriately-sized, but what else factors into a hermit crab’s new shell choices? Is it their mood? Is it the look of the shell? Perhaps it’s something about the shell’s interior that they like?

Get a peek at a hermit crab’s abdomen (a crabdomen?!) as these two hermit crabs make the move, above and below:
