Elasmobranchii (sharks and rays) > Squaliformes
(Bramble, sleeper and dogfish sharks) > Etmopteridae
Etymology: Etmopterus: Greek, ethmos, -ou = sieve or ethmoides bone + Greek, pteron = wing, fin (Ref. 45335).
Environment / Climate / Range
Marine; bathydemersal; depth range 300 - 2213 m (Ref. 5951), usually 300 - 2000 m (Ref. 35388). Deep-water; 65°N - 13°N, 77°W - 16°E
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 55 - ? cm
Max length : 75.0 cm TL male/unsexed; (Ref. 247)
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).
Found on the continental slopes. Probably fished in the eastern Atlantic but details not known. Ovoviviparous (Ref. 205).

Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00324 (0.00151 - 0.00694), b=3.10 (2.90 - 3.30), based on LWR estimates for species & (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.2 ±0.4 se; Based on diet studies.
Resilience (Ref. 69278
): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153
): Moderate to high vulnerability (50 of 100) .
