Hermit crabs

Arthropoda – Malacostraca

Distribution:   Gascoyne Coast Bioregion

Hermit crabs are not connected to the shell on their back, so as they grow, they need to find larger shells to move into. When they have found a larger shell, they crawl out of their old shell and move into their new shell. They are mainly nocturnal and feed during the night, though you do see them moving during the daylight hours. They are social animals and like to feed and sleep in groups.

Hermit crabs have gills but can survive on land as long as their gills stay moist.
