Redescription of the sea anemones Anthopleura hermaphroditica and Bunodactis hermafroditica (Cnidaria: Anthozoa: Actiniaria) from Chile

The Chilean sea anemones Anthopleura hermaphroditica and Bunodactis hermafroditica have been confused repeatedly due to ambiguity in the definition of their diagnostic features. The present article re-describes and compares both species in relation to their synonymic history by examining the externa...
