Lethrinus olivaceus, common name longface emperor or long-nosed emperor, is a species of bony fishes belonging to the family Lethrinidae.

Description[]

A different pattern of Lethrinus olivaceus

Lethrinus olivaceus can reach a length of about 70–100 centimetres (28–39 in). This large lethrinid has a very long snout, with dark wavy streaks. The basic color of the body is olive-grayish, usually with various irregular darker blotches, but it can have different colour and pattern for a better camouflage. It has 10 dorsal spine, 9 dorsal soft rays, 3 anal spines and 8 anal soft rays. Juveniles show a more forked caudal fin. This species is very similar to Lethrinus microdon.[3][4][5]

Distribution[]

This species is widespread in Indo-West Pacific, from Red Sea and East Africa to Samoa and Ryukyu Islands.[3][5]

Lethrinus olivaceus from French Polynesia

Habitat[]

It is a reef-associated species and it can be found in lagoons, in sandy coastal areas and in reef slopes, at depths of 1 to 185 m.[4][5]

Biology[]

These very active and fast swimming fishes often occur in large schools, but adults are usually solitary. They are occasionally found in small schools with Lethrinus microdon.[6] They feed mainly on crustaceans, cephalopods and fishes.[4]
