Elasmobranchii (Haie und Rochen) (sharks and rays) >
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
Ökologie
seewasser bathydemersal; tiefenbereich 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).
Length at first maturity / Size / Gewicht / Alter
Maturity: Lm ?, range 55 - ? cm
Max length : 94.0 cm TL Männchen/unbestimmt; (Ref. 106604)
Found on the continental slopes. Probably fished in the eastern Atlantic but details not known. Ovoviviparous (Ref. 205).
