Adamsia is a genus of sea anemones. Studied primarily in Class 11 Animal Kingdom, it is an excellent example of mutualism (symbiosis) in the marine ecosystem.
Adamsia exists only in the 'polyp' form (sessile and cylindrical). It does not have a 'medusa' stage.
It exhibits radial symmetry.
It has a gastrovascular cavity with a single opening acting as both mouth and anus.
Its common name is the Sea Anemone. Like all Cnidarians, it possesses stinging cells called cnidoblasts used for defense and capturing prey.
Adamsia is famous for its mutualistic relationship with the hermit crab (Eupagurus).
Adamsia belongs to the phylum Cnidaria (also known as Coelenterata).
