Description

edit
 
Adult blue triggerfish from the Egyptian Red Sea

Pseudobalistes fuscus can reach a length of 55 centimetres (22 inches) in males. The body is mainly brown, but fins have yellow margins. Juveniles are yellowish brown with a network of brilliant bluish wavy lines. With growth these lines become interconnected.[2]

This fish is known for its aggressiveness and many divers choose to stay away from them, as they bite often.

Distribution

edit

This species is widespread in the Tropical Indo-Pacific, from the Red Sea to South Africa, Society Islands, southern Japan, Australia and New Caledonia.[2]

Habitat

edit

Pseudobalistes fuscus is a reef-associated species. It prefers coastal waters, shallow lagoons and seaward reefs, at 30–50 metres (98–164 ft) of depth.[2]

Diet

edit

This triggerfish, like most other triggerfish, eats shellfish, small crustaceans, and other bottom-dwelling invertebrae.[2]
