Range of the thorny lanternshark (in blue)

The thorny lanternshark (Etmopterus sentosus) is a shark of the family Etmopteridae found in the western Indian Ocean between latitudes and 31°S, at depths between 200 and 500 m. Its length is up to 27 cm.

Family is one of the eight major hierarcical taxonomic ranks in Linnaean taxonomy; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as being the "walnut family".

Etmopteridae family of fishes

The Etmopteridae are a family of sharks in the order Squaliformes, commonly known as lantern sharks. Their name comes from the presence of light-producing photophores on their bodies. The members of this family are small, under 90 cm (35 in) long, and are found in deep waters worldwide. The 45 species are placed in five genera. Three-quarters of the species are in the genus Etmopterus.

Indian Ocean The ocean between Africa, Asia, Australia and Antarctica (or the Southern Ocean)

The Indian Ocean is the third largest of the world's oceanic divisions, covering 70,560,000 km2 (27,240,000 sq mi). It is bounded by Asia on the north, on the west by Africa, on the east by Australia, and on the south by the Southern Ocean or, depending on definition, by Antarctica.

Reproduction is ovoviviparous.
