Yellowmargin triggerfish

Binomial name: Pseudobalistes flavimarginatus, Eduard Rüppell, 1829

The yellowmargin triggerfish, Pseudobalistes flavimarginatus, are marine fish in the triggerfish family Balistidae. They originate in coastal tropical waters and reefs of the Indo-Pacific from the Red Sea south to Natal, South Africa and east from southern Japan south to Indonesia, Philippines and Samoa. They can be found at water depths from 2–50 m (7–165 ft).

These triggerfish can grow to a maximum length of 60 cm (23 in). They are marketed either fresh or dried for food, but are potentially dangerous in some areas due to ciguatera poisoning.

The yellowmargin triggerfish is oviparous, spawning in pairs. The female fish guard their nests aggressively. When not mating, the fish are solitary or may remain in pairs.

Juvenile fish become adults and some change their shape and colour. Some species change sex and others just get older. Other names for the yellowmargin triggerfish include the yellowmargin trigger, yellowface triggerfish, yellowed-face triggerfish and pineapple trigger.
