More Info


Distribution

Off Northwest Shelf, Western Australia; also the Lord Howe Rise and Norfolk Ridge in the Tasman Sea within Australia's EEZ. Elsewhere the species is circumglobal in tropical and warm temperate seas. An oceanic, mesopelagic species that likely forms schools during the day, migrating upward to 100 to 200 m at night.

Features

Dorsal fin XXX-XVI,35-44; Anal fin II,28-35; Pectoral fin 10-11; Pelvic fin I; Vertebrae 57-64. 
Body extremely elongate, compressed; lower jaw extending anterior to upper jaw with a small conical dermal process; upper jaw with 3 immovable, and 3-4 movable fang-like teeth anteriorly. Anus situated midway between tips of snout and caudal fin (in front of first anal fin spine by distance equal to or greater than snout length). 
Pelvic fin comprising one minute spine; first dorsal fin base about twice length of second dorsal fin base. Anterior portion of anal fin almost lacking fin membrane.
Lateral line single, positioned closer to ventral profile than dorsal profile posteriorly.

Feeding

Feeds on crustaceans and small fishes.

Biology

Females mature at ~16 cm, and produce about 1200 eggs throughout the year. The eggs and larvae are pelagic.

Etymology

The specific name multistriatus is from the Latin multi- (= many) and striatus (= striped), in reference to the many (about 50) very fine longitudinal lines along the side.
