''Epiactis'' is a genus of sea anemones in the family Actiniidae. There are about nineteen recognised species and the type species is ''Epiactis prolifera''. ==Taxonomy== A revision in 1989 determined that the genus ''Cnidopus'' was a synonym of ''Epiactis''. At this time, two new species, ''E. lisbethae'' and ''E. fernaldi'' were described and ''E. ritteri'' was restored to the genus in which it was originally placed. Four species of ''Epiactis'' are known from the Pacific coast of North America, the external brooders ''E. prolifera'' and ''E. lisbethae'' which differ in sexuality and brooding periodicity, and the internal brooders ''E. ritteri'' and ''E. fernaldi'', which differ in their cnidocyte armoury, sexuality and histology.〔Fautin, Daphne Gail and Fu-Shiang Chia. 1986.
