Characteristics:
This hermit crab is easiest identified by the cloak anemone it carries on its back. The anemone expands as the hermit crab grows and resolve the need for shell changes. The close cooperation between these two neighbors involves protection and food supply. If the hermit crab feels threatened in any way, it uses chemical or mechanical signals to get the anemone to spread out its long pink tentacles. In return the anemone gets to eat the remains from the hermit crab's meals. Young hermit crabs catch young cloak anemones. They grow up together and rarely switch partners.
Habitat:
This hermit crab is most frequent between the intertidal zone and a depth of 40 meters depth. It can be found on virtually all kind of substrates.
Distribution:
It is known from the Atlantic coasts of Europe including the British Isles, the Mediterranean, the Red Sea and the Azores.
