Summary:

Voracious mesopelagic predators with dorsolaterally-directed semi-tubular eyes, and large mouths with enormous fang-like teeth in the lower jaw and roof of the mouth.

Sabretooth fishes have extremely distensible stomachs and can swallow very large prey items. They are synchronous hermaphrodites, meaning that they have functional male and female reproductive tissue at the same time.

More Info


Distribution

Circumglobal in tropical and temperate waters between about 10° and 35° latitude.

The Atlantic Sabretooth lives in oceanic midwaters at depths of 50-500 m in Australian waters, 50-1000 m elsewhere.

Features

Meristic features: Dorsal-fin rays 11-13; Anal-fin rays 26-30; Caudal-fin rays 19; Pectoral-fin rays 12-13; Pelvic-fin rays 9; Vertebrae 48-50.

Moderately elongate, compressed, deepwater fishes of open ocean with large mouth and prominent teeth, anteriormost pair on roof of mouth produced into enormous fangs; lower jaw deep and massive, upper and lower muscle masses on rear of body separated by distinct 3rd midlateral muscle band, and no fleshy keels on caudal peduncle or normal scales; gill rakers absent.

Centre of short-based dorsal fin just forward of middle of back, prominent adipose dorsal fin posteriorly, moderately long-based anal fin just before tail, caudal fin deeply forked and pectoral fins prominent; lateral line midlaterally on side.

Size

18.5 cm SL

Colour

Iridescent brassy-brown with scattered small black spots, especially along the ventral midline and the anal-fin base; dorsal surface and midlateral muscle mass slightly darker.

Feeding

Carnivore - a visual predator that feeds on fishes and cephalopods. Sabretooth fishes have highly distensible stomachs and can swallow very large prey.

Fisheries

Of no interest to fisheries
