Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 91; Anal soft rays: 64; Vertebrae: 54. This species is distinguished from its congeners by the following characters: 5-6 developed rakers on anterior gill arch; spineless frontal plate and ethmoid; thin and transparent skin; below the translucent head skin are numerous neuromasts arranged in five distinct clusters; no scales; 3 developed rakers on anterior gill arch are 3-4 times length of gill filaments; palatines with a row of teeth; lower angle of preoperculum with antero-ventrally directed spine; pectoral peduncle prolonged; vertebrae, precaudal 16, total 54; fin rays, D 91, Al 64 and pectoral 14 (Ref. 93007).

Rare species, known from a single specimen (Ref. 34024).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00447 (0.00172 - 0.01163), b=3.10 (2.87 - 3.33), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 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 (10 of 100).
