Short description Identification keys | Morphology | Morphometrics

Vertebrae: 173 - 183. This species is distinguished from its congeners the following characters: body is more elongate with depth at anus 2.2-5.9 %TL, more delicate and flexible; head is shorter 7.1-9.5 %TL, 25.6-36.2 %PAL, 1.8-2.8 times in trunk; dorsal-fin origin is well behind the tip of pectoral fin; vertebrae more numerous 173-183; supratemporal pore present; fleshy papillae on lower jaw, but not dorsally on head; no sensory pits on the ventral surface of head and anterior body (Ref. 129313).

Estimates based on models

Preferred temperature (Ref. 123201): 8.9 - 16.3, mean 12.3 °C (based on 32 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00063 (0.00029 - 0.00138), b=3.18 (3.00 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.5 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (52 of 100).
