Adamsia is also known as the sea anemone. It is mainly marine and is attached to the shell of gastropods. They are commensal organisms and show an association between sea anemone and the hermit crab. These organisms live together in which one organism is neither harmed and nor benefited while the other organism gets benefited. Adamsia moves from one place to the other by the help of hermit crab. Their body is divided into pedal disc, oral disc and column. The oral disc constitutes mouth and tentacles while the pedal disc helps in attachment.
