Short description Bestämningsnycklar | Morfologi | Morfometri

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).

Trofisk nivå (Ref. 69278): 4.2 ±0.5 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Låg, lägsta populationsfördubblingstid 4,5-14 år (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (35 of 100).
