Squaliformes (Sleeper and dogfish sharks) >
Etmopteridae (Lantern sharks)
Etymology: Etmopterus: Greek, ethmos, -ou = sieve or ethmoides bone + Greek, pteron = wing, fin (Ref. 45335).
Eponymy: Richard Hill (1795–1872) was a Jamaican anti-slavery activist, judge, botanist and naturalist who was in England (1827–1830) and was closely involved with men like Wilberforce and other prominent members of the Anti-Slavery Society. [...] (Ref. 128868), visit book page.

Inhabits the upper continental and insular slopes. Found on sandy bottoms (Ref. 26340). Ovoviviparous with 4 to 5 young in a litter. Maximum size reported in Ref. 106604 after Bigelow & Schroeder (1948). Maximum sizes of 31.5 cm precaudal length (Longley & Hildebrand,
1941) and 50.0 cm TL (Ref. 247) probably refer to the subsequently described and very similar E. robinsi, which attains a greater maximum size according to Schofield & Burgess (1997) (Ref. 106604).
