Description

The goldlined seabream is an emperor (Lethrinidae) from the Indo-Pacific. The species has an elongate, silvery body with golden-yellow and brown lengthwise lines, large eyes and a white blotch below the rear dorsal fin. By day it forms schools above reef flats, lagoons and seaward reefs; at night it disperses to hunt. As a bottom hunter it feeds on small crustaceans, molluscs, sea urchins and small fishes. It is a food fish. The species is harmless to humans.
