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.
