Abyssal Grenadier, Coryphaenoides armatus (Hector 1875)

More Info


Distribution

Common in deep waters of most oceans at relatively high latitudes. Known from off Eastern Australia, Tasmania, the Great Australian Bight, and Australia's subantarctic waters. A common inhabitant on the deep-slope, upper continental rise and abyssal plain in the bathypelagic zone of the most ocean basins.

Feeding

Juveniles feed mostly on benthic invertebrates such as crustaceans and holothurians, while adults feed on mesopelagic and bathypelagic fishes, sea urchins and cephalopod molluscs.

Fisheries

Although not commercially targeted, the species is is taken as bycatch in deepwater fisheries in parts of its range.
