Epiactis

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.
