Southern lanternshark explained

The southern lanternshark (Etmopterus granulosus) is a shark of the family Etmopteridae found in the southeast Pacific between latitudes 29°S and 59°S, at depths of between 220 and 1,460 m. This species has been found off Northland, off the Chatham Islands, on the Campbell Plateau, all in New Zealand waters.[1] Its length is up to 60 cm. Reproduction is ovoviviparous, with 10 to 13 pups in a litter, length at birth about 18 cm.[2] They exhibit bioluminescence.[3]

Parasites of the southern lanternshark, studied off Chile, include Monogeneans, Digeneans, Cestodes, Nematodes, and Copepodes.[4]

In June 2018 the New Zealand Department of Conservation classified E. granulosus as "Not Threatened" with the qualifier "Secure Overseas" under the New Zealand Threat Classification System.[5]
