Identification: The Rectangular Triggerfish is easily recognized by the "black wedge" near the tail, thus giving this fish its other common Wedgetail names. It has bright blue, green, golden-brown, yellow, red, black and white line markings, a distinctive large wide black band on the sides of the body and red lips, all of which makes it an easy to identify species.
Scientific Name: Rhinecanthus rectangulus (Bloch & Schneider, 1801).
Other Common Names: Humu-Humu, Black-Wedgetail, Wegde-Tail, Pig-Nosed, Reef, and Painted Triggerfish. This fish is also "tagged" with the Picasso name, but the Rhinecanthus aculeatus species is the "true" Picasso Triggerfish.
Hawaiian Name: Hu-mu hu-mu nu-ku nu-ku a pu-a-'a. Both the Rhinecantus rectangulus and aculeatus bear this famous long Hawaiian name. Roughly translated this name means "fish with a pig-nosed face". In short, this and most all other Triggerfishes worldwide are referred to commonly as Humu-Humu's, and sometimes incorrectly as Huma-Huma's, but these names do not actually identify an individual species one may have.
