Overview
Found singly, pairs or in a consortium, living commensally with sea pens, over coral and rocky reefs.
They feed nocturnally, by spreading their arms to collect their prey of zooplankton.
Anomura crabs are considered false crabs, they have a longer abdomen and the back legs are modified or reduced so hardly noticeable.
These crabs include the hermit crabs and squat lobsters.
Many thousands of species live worldwide in sea water, fresh water and on land.
