Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 94; Anal soft rays: 79; Vertebrae: 53. Rather elongate body with blunt head; eye almost as long as snout; upper jaws ends well behind eye; 3 sharp spines on preopercle and 1strong opercular spine; 1 median and a pair of basibranchial tooth patches; 5-6 developed rakers on anterior gill arch; pelvic fins inserted beneath eye and extended well beyond head; precaudal vertebrae 13 (Ref. 34024). Snout spine present (Ref. 34024).

Rare 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

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00380 (0.00167 - 0.00864), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.6 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 (47 of 100).

Price category (Ref. 80766): Medium.
