The lagoon triggerfish (Rhinecanthus aculeatus), also known as the blackbar triggerfish, the Picasso triggerfish, thePicassofish, and the Jamal, is a triggerfish, up to 30 cm in length, found on reefs in the Indo-Pacific region. The Hawaiian name for the fish, humuhumunukunukuāpuaʻa, (meaning “triggerfish with a snout like a pig”) shares the same name with the reef triggerfish, the state fish of Hawaii. This species has been studied in a range of research contexts, from locomotion to colour vision research.
