Lethrinus olivaceus, common name Longface emperor or Long-nosed emperor, is a species of bony fishes belonging to the family Lethrinidae.
Description
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. [2] [3][4]
Distribution
This species is widespread in Indo-West Pacific, from Red Sea and East Africa to Samoa and Ryukyu Islands. [2][4]
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. [3][4]
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. [5] They feed mainly on crustaceans, cephalopods and fishes. [3]
