Striped large-eye bream (Gnathodentex aureolineatus), is a species of emperor. It is currently the only known member of its genus.
Striped large-eye bream is a medium-sized fish which can grow up to a maximum length of 30 cm, however the commonly observed size is 20 cm. Its body is compressed laterally, the snout is pointed and the tail is forked. The background coloration is silver-grey with golden horizontal lines on the sides, these later are topped by dark horizontal lines. Its fins have pinkish shades, a yellow mustache-like line overcomes the upper lip, the junction of the pectoral fins to the body is marked with yellow and also along the outer edge of the operculum. A golden yellow spot located on the back at the termination of the dorsal fin is a hallmark of this species. In proportion to body size, the eyes are quite large.
Gnathodentex aureolineatus is generally found on coral reefs at depths of 3-30 m (Carpenter 2001). It is found in sub-tidal reef flats, lagoons, and foreslopes (Lieske and Myers 1994). This species occasionally forms aggregations of up to and over one hundred individuals (Carpenter and Allen 1989). It is a nocturnal consumer, feeding on benthic invertebrates including crabs and gastropods, and are known to occasionally feed on fish as well. The maximum recorded length for this species is 30 cm (Carpenter and Allen 1989).
