Allantactis is a monotypic genus of sea anemones, and Allantactis parasitica is the only species in the genus. This sea anemone lives at bathyal depths in the North Atlantic Ocean and has a symbiotic relationship with a gastropod mollusc.
==Description== A. parasitica has a strong base and a smooth column with thick walls and no cuticle or perforations of the body wall that are termed cinclides. The margin is distinct and the sphincter powerful. The tentacles are fairly short and arranged in whorls of six, there being a maximum of 96. The oral disc has a central mouth with two broad siphonoglyphs. The six pairs of mesenteries are complete, in that their sheetlike membranes join the gastrodermis of the body wall with that of the pharynx, and are sterile, in that they do not bear gonads. The nematocysts consist of a mixture of spirocysts, basitrichs and microbasic p-mastigophors.
