Short description Identification keys | Morphology | Morphometrics

This species is distinguished by the following characters: precaudal vertebrae 16-17; first gill arch with long gill rakers 15-18; pectoral-fin rays 15-18; HL:HD 1.49-1.73; few and mostly weak head spines on ethmoidal, supraorbital, sphenotic, supratemporal, outer posttemporal, inner preopercular rim while absent on lacrimal, prefrontal, interorbital, 5th infraorbital, inner posttemporal, outer preopercular rim; opercular spine weak and flat; opercular flap small; lower lateral line pores until beginning of anal fin 15-17; narrow dentition patch on vomer with 1-2 rows of teeth while palatines with moderately broad dentition patch with 3–4 rows of teeth; otolith with single colliculum; OL:OH = 1.0–1.2; OL:TCL = 1.8 (Ref. 125143).

Uncommon species (Ref. 34024). Reproductive strategy possibly similar to other members of this family featuring oviparity, with oval pelagic eggs floating in a gelatinous mass (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 115969): 2 - 4.3, mean 4.1 (based on 286 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.6 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (17 of 100).
