Pseudobalistes fuscus (common names: blue triggerfish, rippled triggerfish, yellow-spotted triggerfish and blue-and-gold triggerfish) is a fish belonging to the familyBalistidae.[2][3]
Juvenile Pseudobalistes fuscus
Description
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.
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
This triggerfish, like most other triggerfish, eats shellfish, small crustaceans, and other bottom-dwelling invertebrae.[2]
