Zanclidae

species of fish

Zanclidae is a family of marine ray-finned fishes belonging to the suborder Acanthuroidei within the order Acanthuriformes. It contains one extant species, the Moorish idol (Zanclus cornutus) and a number of extinct species.

Eozanclus ("dawn Zanclus") is an extinct genus of marine ray-finned fish, closely related to the modern Moorish idol, that lived during Eocene. It contains a single species, E. brevirostris that lived during the late Ypresian epoch in what is now Monte Bolca, northern Italy. It is one of two known fossil Moorish idols from Monte Bolca alongside Angiolinia. It differs from its living relative by having a much shorter snout.
