Very little literature exists for this next demersal shark: the Hawaiian lanternshark (Etmopterus villosus). If you guessed by the scientific name that it is a lanternshark, you would be correct! Endemic to Molokai in Hawaii, they are found on or near the bottom here at about 406-911 metres depth and therefore scientists and conservationists aren’t worried about fishing pressure. They are known from only a handful of specimens, and have a maximum total length of 46 cm (1.5 ft).
Hawaiian lanternsharks are in the Etmopteridae family, and like other lanternsharks are dark brown to black in colour all around. They have a short little tail, short fin, and a spine to protect them in front of each dorsal fin. They are also known as “green eye sharks” for their large green eyes!
The IUCN has assessed these animals as Least Concern (LC).
