Introduction
The Shortsnout Lancetfish is a slender species with large fangs. It occurs in deep temperate waters in most oceans.
Identification
The Shortsnout Lancetfish has a slim, elongate body. It has a long-based first dorsal fin followed by a small adipose fin. The caudal fin is large and forked. The anal fin is short-based and positioned posteriorly on the body.
The species has a large mouth with large fangs on the roof of the mouth and at the front of the lower jaw. There are smaller triangular and caniniform teeth elsewhere on the jaws and the roof of the mouth.
It is iridescent brownish-black above and paler laterally. The long lateral keels at the rear of the body are black. The dorsal fin may have a row of white spots close to its base.
