Lutjanus bohar
Introduction '''''Lutjanus bohar''''', the '''two-spot red snapper''', the '''red bass''', '''twinspot snapper''' or '''bohar snapper''', is a species of marine ray-finned fish, a snapper belonging to the family Lutjanidae. It has a wide Indo-Pacific distribution.
Taxonomy ''Lutjanus bohar'' was first formally described as ''Sciaena bohar'' in 1775 with no type locality given, although it is thought to be the Red Sea. The description is attributed to the Finnish-born Swedish explorer Peter Forsskål by FishBase, but the ''Catalog of Fishes'' attributes as follows“''Fabricius J. C. in Niebuhr (ex Forsskål) 1775:46, xi Descriptiones animalium (Forsskål)''”''Catalog of Fishes'' then states that the valid binomial is ''Lutjanus bohar'' (Fabricius, 1775).The specific name ''bohar'' is the Arabic word used for this fish in the Red Sea.
Description The two-spot red snapper can reach a length of , though most do not exceed . The greatest recorded weight for this species is . These large reddish tropical snappers show darker fins, a rounded profile of head and a groove running from the nostrils to the eyes. They have 10 dorsal spines and 3 anal spines. Juveniles and some adults have two silvery-white spots (hence the common name) on the back close to their dorsal fins, while larger adults lose the spots and become mostly red. Large adults may cause ciguatera poisoning.This species is a commercially important species and is also sought-after as a game fish.
Biology Close-up It is a long-lived and slow-growing species which reaches maturity at 8–9 years, and the oldest recorded individual is 56.These fishes are carnivorous, mostly feeding on other fishes, crustaceans and molluscs.Adult snappers often form large schools on the outer reefs or above sandy areas, mainly to form spawning aggregations. Small brownish juveniles mimic damselfishes of the genus Chromis in order to approach their prey.Two chambered nautiluses feeding on a two-spot red snapper.The chambered nautilus, ''Nautilus pompilius'', is known to scavenge deceased snappers. A pair of nautiluses recorded feeding on a snapper at 703 metres below the surface constitutes the deepest recorded sighting of any nautilus species.
Distribution This species is native to the Indian Ocean. It is widespread in the Indo-Pacific from the east African coast, north to the Red Sea, to the western Pacific Ocean, north to the Ryukyu Islands, south to Australia.
Habitat It is a coral reef inhabitant, being found at depths from , though usually between .
