Summary:

A uniformly blackish deepwater shark with a short, blunt snout, fleshy lips, large triangular serrated teeth in the lower jaw, small, narrow and awl-shaped with smooth edges in the lower jaw and no fin spines.

This species is the largest known bioluminescent vertebrate, and is the first known shark to have fully luminous dorsal fins.

Black Shark, Dalatias licha (Bonnaterre 1788)

More Info


Distribution

Off Swains Reefs, Queensland, throughout southern Australia to near Rowley Shoals, Western Australia; also the Lord Howe Province in the Tasman Sea. Elsewhere the species is widespread with a patchy distribution in the Atlantic and Indo-West Central Pacific.

Inhabits the continental shelf and slope in depths of 37-1800 m, although mostly in 450-850 m in Australian waters.

Features

Vertebrae 75–85 (47–55 precaudal)

Preoral length 4–8% TL; upper teeth smooth-edged, thorn-like, on broad bifid bases, curved rearwards, outwardly oblique; lower jaw teeth triangular, serrate, on square bifid bases, lateral teeth notched on outer side, each overlapping next outer tooth.

Size

Reaches 1.8+ m TL, although individuals are commonly about 120 cm TL.

Colour

Uniformly violet-black to dark grey or brown, with pale lips, green eyes, and pale or translucent trailing edges on the fins.

Feeding

Feeds on small demersal sharks such as lanternsharks, gulpersharks and catsharks, along with demersal bony fishes, crustaceans, and cephalopod molluscs.

Biology

Like all sharks, the sexes are separate and fertilization is external. Kitefin sharks are live bearers, and reproduction is lecithotrophic viviparous. Males mature ~100 cm TL; females mature ~120 cm TL; size at birth 30-40 cm TL; litter size is 3-16 pups (average 6-8).

Fisheries

Taken as incidental bycatch in midwater and benthic trawl, surface and benthic longline, and in setnet fisheries throughout its range.

Conservation

  • IUCN Red List : Vulnerable

Remarks

Black Sharks have asymmetrical teeth. The upper jaw teeth are small, narrow and awl-shaped with smooth edges. The larger lower jaw teeth are erect and broadly triangular, with serrate cusps and overlapping bases. This arrangement enables them to gouge out chunks of flesh from large fast swimming epipelagic fishes - like the related cookiecutter sharks.

Etymology

The specific name licha is based on 'La Liche' of Broussonet, 1784, the first account of this species.
