# Pomacanthus

Pomacanthus is a genus of marine angelfish that is usually found around reefs and coral. Some of the notable places one can see these vari-coloured fish includes the Maldives, Sri Lanka, and Sipidan off the southern coast of Sabah, Malaysia. Generally the patterns and colors of these fish undergo a major transformation from juvenile to adult forms. The juveniles may even appear to be a different species.

## Systematics

The genus Pomacanthus was created in 1802 by the French naturalist Bernard Germain de Lacépède (1756-1825) with the type species being designated as Chaetodon arcuatus. The name is a compound of poma meaning"lid" and acanthus which means "thorn", a reference to the prominents spine on the rear margin of the operculum, a feature shared by all the marine angelfishes.
