title: Marine fauna of Mljet National Park (Adriatic Sea, Croatia). 7. Echiura
abstract: It seems that the only Echiuroid species present in the Mljet National Park is Bonellia viridis. This species is known world wide for its peculiar larval development and sexual dimorphism. The forked proboscis females prefer to live in shallow sublittoral crevices in large stones and similar rocky environments. Divers reported B. viridis to be a rather common marine invertebrate.
