Squaliformes (Sleeper and dogfish sharks) >
Etmopteridae (Lantern sharks)
Etymology: Etmopterus: Greek, ethmos, -ou = sieve or ethmoides bone + Greek, pteron = wing, fin (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
البيئة
بحري قاعية المعيشة; نطاق العمق 300 - 2213 m (Ref. 5951), usually 300 - 2000 m (Ref. 35388). Deep-water; 69°N - 13°N, 77°W - 16°E
Northwest Atlantic: Nova Scotia, Canada to New Jersey, USA. Northeast Atlantic: southern Iceland along Atlantic slope to Faeroes, Hebrides, UK, English Channel, Bay of Biscay and Gibraltar, Mauritania. Nominally recorded from New Caledonia in the Western Central Pacific, but its status there needs clarification - other large species of lanternsharks (Etmopterus baxteri and Etmopterus unicolor) may be involved (Ref. 31367).

Maturity: Lm ?, range 55 - ? cm
Max length : 94.0 cm TL ذكر/ مختلط الجنس; (Ref. 106604)
Found on the continental slopes. Probably fished in the eastern Atlantic but details not known. Ovoviviparous (Ref. 205).
