Lutjanus sebae

Lutjanus sebae was first formally described in 1816 as Diacope sebae by the French zoologist Georges Cuvier, Cuvier did not give a type locality but it is thought to be either the Coromandel Coast of India or so where in Indonesia. The specific name honours Albertus Seba, a Dutch pharmacist, zoologist and natural history collector, who published a Thesaurus of animal specimens with beautiful engravings in 1734. This included examples of marine life from the Indo-Pacific, including an illustration of the emperor red snapper. ==Description==

Lutjanus sebae has a very deep body, its standard length being just over twice its depth. The forehead is steeply sloped, the snout has a straight or convex upper profile and the knob and incision on the preopercle are moderately developed. The vomerine teeth are arranged in a crescent shaped or triangular patch with no rearwards extension and there no teeth on the smooth tongue. The dorsal fin has 11 spines and 15-16 soft rays and the anal fin has 3 spines and 10 soft rays, ==Distribution and habitat==

Lutjanus sebae has a wide Indo-Pacific distribution from Eastern Africa where its range extends from the southern Red Sea to South Africa east into the Pacific Ocean as far as New Caledonia, south to Australia and north to southern Japan. In Australian waters this species can be found from Bunbury, Western Australia around the coast to Sydney. This species is an inhabitant of both rocky and coral reefs, preferring flat areas with either a sandy or gravel substrate. ==Biology==

Lutjanus sebae is a predatory fish which feeds on different fish, benthic crustaceans and cephalopods. It aggregates into schools with similar sized individuals or they will be solitary. This is a slow growing species, off the Seychelles, the mean age of first sexual maturity for both males and females was estimated at 9 year old. The size at which 50% of fishes are sexually mature was between fork lengths of . Once they are sexually mature the females growth rate decreases compared to the males, and adult males grow larger than females. Red emperor snappers form spawning aggregations between October and April, eggs and milt are broadcast in these aggregations. They are long lived, maximum longevity is as much as 40 years. Juveniles have been observed swimming among the spines of sea urchins. The larger adults move to deeper waters but frequently return to shallower water in the winter. ==Fisheries==

Lutjanus sebae is commercially important and is also farmed. It is sought as a game fish and is found in the aquarium trade. ==In culture==

Lutjanus sebae is also known as the government bream in Australasia, for the red bars on the juvenile form suggesting the fish is wrapped in red tape. ==Gallery==
