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).
Apparently restricted to eastern Australia (Ref. 87957); distribution to be resolved when new studies or publications are received.
Environment / Climate / Range
Marine; bathydemersal; depth range 250 - 860 m (Ref. 26346). Deep-water, preferred ?; 34°N - 46°S
Western Pacific: Japan, Australia, and New Zealand (Ref. 6871). Apparently restricted to eastern Australia (Ref. 87957).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 46.0 cm TL male/unsexed; (Ref. 6871)
soft rays: 0. Light brown above, black below, with a pale stripe on side and a black streak above and behind pelvic fins; belly luminous (Ref. 26346). Small and slender, with a moderately elongate caudal peduncle and with flank denticles mostly arranged in regular rows. The base of the pelvic flank markings is inserted in advance of the origin of the second dorsal-fin spine, the anterior branch is shorter than the posterior branch, and the caudal marking is longer than the precaudal marking (Ref. 6871).
Probably demersal (Ref. 31367) on upper continental slopes (Ref. 6871). Ovoviviparous (Ref. 205), size at birth about 15 cm (Ref. 6871).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00347 (0.00155 - 0.00778), b=3.10 (2.90 - 3.30), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.2 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Very Low, minimum population doubling time more than 14 years (Assuming Fec<10).
Vulnerability (Ref. 59153
): Moderate vulnerability (39 of 100) .
