Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 32 - 35; Raggi dorsali molli (totale) : 0; Vertebre: 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).

Trophic level (Ref. 69278): 3.2 ±0.42 se; based on food items.

Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Assuming tmax>10).

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