Summary:
An iridescent dark bluish lancetfish becoming silvery-white below, with bluish fins. The species has a high sail-like dorsal fin, long pectoral fins, a short snout (less than one-third the head length), and enormous teeth. The dorsal fin is rounded without elongate free rays, and originates before the hind margin of the gill cover.

More Info


Distribution

Southern Tasmania to off Perth, Western Australia; also Macquarie Island and presumably near Heard & McDonald Islands in the Southern Ocean. Elsewhere the species is circumglobal in tropical, temperate and subantarctic waters (except the North Pacific). Inhabits mesopelagic and bathypelagic depths.

Features

Dorsal fin 40-48; Anal fin 13-16; Pectoral fin 12-14; Pelvic fin 8-10; Gill rakers 23-29.

Specimens larger than 50 mm SL - head more than 6.2 in SL, snout less than one-third HL. Dorsal-fin elongate, tall, sail-like, origin in front of posterior margin of operculum; dorsal fin without free rays, low anteriorly, forming a curve that is highest near the middle; dorsal adipose fin present.

Feeding

A voracious predator that feeds on pelagic crustaceans and fishes.

Biology

A simultaneous hermaphrodite with functional ovarian and testicular tissue in an ovotestis.

Similar Species

The Longsnout Lancetfish, Alepisaurus ferox, has a relatively longer head and snout (specimens longer than about 50 cm SL), the dorsal fin originates above or behind rear margin of the gill cover, and is tall anteriorly with several free rays near the front of the fin. 

Etymology

The specific name brevirostris is from the Latin brevis (= short) and rostris (= snout), in reference to the relatively shorter snout compared with that of Alepisaurus ferox
