Etymology: Etmopterus: Greek, ethmos, -ou = sieve or ethmoides bone + Greek, pteron = wing, fin (Ref. 45335); pseudosqualiolus: From its similarity of general body shape with squaloid sharks.
More on authors: Last, Burgess & Séret.

Short description Identification keys | Morphology | Morphometrics
Body cigar-shaped; deep head conical with a short bulbous snout; preoral length 7.3-8.2 % TL. Eye almost round with a small opalescent lunate patch on upper eyelid margin. Pectoral fins small, rear tip about cornea diameter in front of D2 origin. Dorsal and ventral coloration dark; white conspicuous pineal blotch small and triangular. Caudal peduncle short (14.8-16.6% TL). Upper teeth of mature males usually with 7 cusps, others 9-11, in separated rows; central cusps greatly expanded, about 2 times longer than those adjacent. Denticles small, with a single erected, slightly curved cusps, arranged in irregular rows. Anterior branch of pelvic marking long and slender, posterior branch truncated. Precaudal marking with very long finger-like extensions reaching to central caudal fin. Monospondylous centra 46-47 (Ref. 45056).
Ovoviviparous (Ref. 205).

Estimates based on models
Preferred temperature (Ref. 123201): 3.2 - 4.5, mean 3.9 °C (based on 85 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00380 (0.00194 - 0.00745), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278): 4.2 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153): Moderate vulnerability (35 of 100).
