Description

The glasseye is a nocturnal reef fish of the family Priacanthidae reaching about 50 cm. The deep, laterally compressed body is usually bright red, sometimes with silvery blotches or bars, and can quickly change colour and pattern. Striking are the very large eyes, adapted to hunting in the dark, and the rough skin with fine scales. The species occurs worldwide in tropical and subtropical seas and also appears in the Mediterranean and around warm Atlantic islands. By day it shelters near reefs, caves and wrecks; at night it hunts small fish, crustaceans and squid. Large specimens can cause ciguatera poisoning if eaten.
