Short description Morfologia | Morfometria

Spine dorsali (totale): 2; Raggi dorsali molli (totale): 33-37; Spine anali 0; Raggi anali molli: 30 - 35; Vertebre: 42 - 46. Caudal fin rounded and narrow; pectorals broad (Ref. 6885). Olive brown to bronze or dark iridescent purple on dorsal surface, paler on sides with a golden yellow on ventral surface; white space under eye with a black crescent below; white on posterior edge of maxillary; young with a weak dark dorsal saddle (Ref. 6885). Branchiostegal rays: 6 (Ref. 36489).

Ranges from intertidal areas (where they may remain out of water under rocks or seaweeds, Ref. 31184) to deeper water over sand and mud bottoms (Ref. 4925). Adults make vertical migrations at night (Ref. 6885). Feed on crustaceans and fishes (Ref. 6885). Oviparous with eggs and larvae attached to nest wall (Ref. 36489). Nest is guarded by male (Ref. 36489). Important prey item for seals and sea lions (Ref. 2850). Adults breathe air when out of water (Ref. 31184). Possess photophores which are arranged on the underside of the head in a 'U' fashion.

Nests are cavities that are formed under rocks and eggs are deposited on the roof of the cavity. As few as 19 or as much as 789 eggs have been found attached in a nest. Eggs are guarded by the fasting male. Probably polygamous (Ref. 6885).

Bayesian length-weight: a=0.00562 (0.00323 - 0.00980), b=3.16 (3.01 - 3.31), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.67 se; based on food items.

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (tm=3.5; tmax=7).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (28 of 100).
