Short description Morfologi | Morfometri

This relatively large species is distinguished by the following characters: denticles on dorsal midline greatly enlarged from snout to second dorsal origin; denticles on pectoral fin dorsal surface greatly enlarged in adults; no club-shaped papillae on the distal tip of the clasper; buccal papillae in mouth large and prominent on upper and lower surfaces; moderate vertebral count, 124 total vertebrae in the holotype (123 total in paratype, mean 117.8); relatively high tooth counts, 65 total upper teeth in the holotype (66 in the paratype, mean 66.3), 70 total lower teeth in the holotype (58 in paratype, mean 60.3); covered in irregularly shaped spots and reticulations on a brown background, resembling a honeycomb pattern; white spots rarely present, if present, are inconspicuous (Ref. 75585).

Estimates based on models

Preferred temperature (Ref. 123201): 11.3 - 12.4, mean 11.4 °C (based on 6 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00355 (0.00176 - 0.00714), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 4.2 ±0.6 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Låg, lägsta populationsfördubblingstid 4,5-14 år (Preliminary low fecundity).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (41 of 100).
