Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 59 - 66; Rückenflossenweichstrahlen (insgesamt) : 0; Afterflossenstacheln: 1; Afterflossenweichstrahlen: 41 - 45; Wirbelzahl: 64 - 70. Gray to nearly black to bright spotted with patterns; usually a wavy line extending along back, separating dark portion from lighter spots that continue onto dorsal fin (Ref. 43939). Caudal fin rounded.

Mainly intertidal, but may be found at depths as much as 100 m (Ref. 43939); typically found shallower than 50 meters (Ref. 51666). Often in bays with pebble-rock debris bottoms (Ref. 43939). Oviparous, eggs are guarded by the female parent (Ref. 58332).

Estimates based on models

Preferred temperature (Ref. 123201): 2.3 - 12.9, mean 6 °C (based on 248 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.44 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Preliminary K or Fecundity.).

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