Etymology: Etmopterus: Greek, ethmos, -ou = sieve or ethmoides bone + Greek, pteron = wing, fin (Ref. 45335).

বাস্তুসংস্থান
সামুদ্রিক ব্যথিডিমারসাল সমুদ্র তলদেশবিহারী; গভীরতার পরিসীমা 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).
