Etmopterus is a genus of lantern sharks in the squaliform family Etmopteridae. They are found in deep sea ecosystems of the Atlantic, Indian and Pacific Oceans.[2]

Ecology

A number of species in this genus function as host to the specialized parasitic barnacle Anelasma squalicola, which embeds itself into the skin of the shark and extracts nutrients from its bloodstream.[3]

Species

There are currently 45 recognized species in this genus:

  • Etmopterus alphus Ebert, Straube, Leslie & Weigmann, 2016 (whitecheek lanternshark)[4]
  • Etmopterus baxteri Garrick, 1957 (New Zealand lanternshark)[5]
