Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 101 - 104; Anal soft rays: 86 - 90. Dorsal part of the body with marbled, brownish pigmentation, but lacking ocelli and stripes. Hind margin of preoperculum with 2 spines. Pseudobranchial filaments 2-4. Teeth granular. Ventral fin rays far from reaching anus, 12-14% SL (Ref. 40522).

Common species (Ref. 34024) found to feed on small gastropods and crustaceans (Ref. 32505). 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. 123201): 7.1 - 14.4, mean 10.5 °C (based on 129 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00380 (0.00165 - 0.00876), b=3.14 (2.93 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.54 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
