The hermit crab gains protection from predators by the sea anemone's stinging, and the sea anemone gains an increase in food from the material thrown up by the hermit crab's movements. [3] The relationship is apparently instigated by the sea anemone, which begins a complex series of manoeuvres in order to mount the shell carried by the hermit ...
Dardanus pedunculatus, commonly referred to as the anemone hermit crab, is a species of hermit crab from the Indo-Pacific region. It lives at depths of up to 27 m and collects sea anemones to place on its shell for defence.
Two of the more unusual relationships are those between certain anemones (such as Adamsia, Calliactis and Neoaiptasia) and hermit crabs or snails, and Bundeopsis or Triactis anemones and Lybia boxing crabs. In the former, the anemones live on the shell of the hermit crab or snail.
Adamsia palliata is a species of sea anemone in the family Hormathiidae.It is usually found growing on a gastropod shell inhabited by the hermit crab, Pagurus prideaux. [1] The anemone often completely envelops the shell and because of this it is commonly known as the cloak anemone or the hermit-crab anemone.
Adamsia is a genus of sea anemones in the family Hormathiidae.Species in this genus are mutually symbiotic with hermit crabs. The anemone gets a place to live and discarded scraps of the crab's food in exchange for its help in the crab's defence.
Calliactis parasitica on the hermit crab Dardanus calidus. Calliactis is a genus of sea anemones.Species in this genus are mutually symbiotic with hermit crabs. The anemone gets a place to live and discarded scraps of the crab's food in exchange for its help in defending the crab.
The Enthemonae and a young hermit crab will often develop a symbiotic relationship from a young stage. This involves the young hermit crab attaching the shell to the tentacles of the sea anemone, becoming partners for the duration of their life cycle. This process often results in the two organisms growing at roughly the same rate. [17]
The sea anemone also benefits, because it is in a prime position to consume fragments of the hermit crab's meals. Other very close symbiotic relationships are known from encrusting bryozoans and hermit crabs forming bryoliths .
