Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 32 - 35; Radios blandos dorsales (total) : 0; Vértebra: 242 - 244. Caudal fin very small; anal fin with 161-162 rays altogether, 26-35 of which are spines, long, low, confluent with caudal; pectorals with a fleshy base (Ref. 6885). Cream to faintly pink, possibly with light brown markings; black on posterior margins of anal and caudal fins; black on posterior edge of gill cover, lining of mouth and gill chamber, and parts of peritoneum (Ref. 6885).

Feeds on benthic invertebrates, especially amphipods, polychaetes and mysids (Ref. 6728).

Estimates based on models

Preferred temperature (Ref. 115969): 1.5 - 3.4, mean 2.4 (based on 2854 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5630 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.2 ±0.42 se; based on food items.

Resiliencia (Ref. 120179): Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Assuming tmax>10).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).
