简单描述
型态特徵 | 形态测量图
背棘 (总数): 2; 背的软条 (总数): 33-37; 臀棘 0; 臀鳍软条: 30 - 35; 脊椎骨: 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.
Life cycle and mating behavior

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).
