Description

The onespot snapper is a snapper (Lutjanidae) from the Indo-West Pacific. The species has a yellowish to silvery-brown body and owes its name to a single dark spot on the lateral line below the rear dorsal fin. Adults inhabit coral reefs, usually close to shelter such as caves, large coral formations and wreckage. As a nocturnal predator it hunts fishes and crustaceans. It is a food fish, although in some areas it is associated with ciguatera poisoning. The species is harmless to humans.
