Spiny Pygmy Shark


Scientifically:
Squaliolus laticaudus.

What To Look For:
The smallest shark in the world and the only one with a single spine on the first dorsal fin and none on the second. The tail is spade-shaped and there are pale edges to the fins, and it has well-developed light-emitting organs (photophores) on the underside of the body, which enable individuals to locate one another. It is a wide-ranging species over continental slopes (to depths of 500 m.) and it migrates to the surface at night to feed.

Size:
Up to 25 cm, matures at 15-17 cm.

Distribution:
Worldwide in tropical and temperate seas.

Food:
Deep-water squid and bony fish.

Breeding:
Probably a live-bearer, with up to 12 mature eggs found in a single female.

Danger To Humans:
Not known to be dangerous.
