Family LAMPRIDAE
Large brightly coloured oceanic fishes with a deep body, a low long-based dorsal fin, high and pointed at the front, scythe-like pectoral and pelvic fins, and a large lunate or forked caudal fin. The lateral line is conspicuous and arches high over the pectoral fins.
Opahs are oceanic in epi- to mesopelagic depths, and are rarely seen inshore.
More Info
Family Taxonomy |
A small family of large pelagic fishes found worldwide, with a single genus Lampris, and two species. Both species occur in Australian waters. |
Family Distribution |
Worldwide in tropical, temperate and cold temperate waters. One species occurs in all oceanic tropical and cool oceanic waters, and the other is only found in the Southern Hemisphere south of 30 S. |
Family Size |
To a fork length of more than 1.6 metres. |
Family Colour |
Silvery to bluish or orange to reddish in colour; one species covered in white spots. |
Family Feeding |
Carnivores, known to feed on krill, mesopelagic fishes and squids. A considerable amount of plastic was found in the stomachs of Lampris immaculatus in the Southern Ocean (Jackson et al. 2000). |
Family Reproduction |
Little is known of Lampris biology. Lampris guttatus has specialised pelagic larvae. |
Family Commercial |
Species are highly prized as food fish and are taken as bycatch in pelagic longline fisheries. |
