Maturity: Lm 28.0, range 23 - ? cm
Max length : 42.5 cm TL 雄魚/尚未辨別雌雄; (Ref. 27159); 最大體重: 2.0 kg (Ref. 27124); 最大年齡: 140 年 (Ref. 39383)
背棘 (總數): 5 - 8; 背的軟條 (總數): 28-33; 臀棘 2-3; 臀鰭軟條: 26 - 31. Adults blackish black in color; prejuveniles silvery, back greenish with large grey blotches that disappears at about 12 cm (Ref. 6548).
Occurs on the continental slope (Ref. 9563), forming large shoals over rough ground near pinnacles and canyons (Ref. 6390). Juveniles are pelagic and inhabit oceanic waters in depths of less than 1000 m (Ref. 27230). They tend to be dispersed over smooth grounds (Ref. 6390). Feeds on shrimps, cephalopods, and fishes (Ref. 6548). The eggs float near the sea surface and the larvae also inhabit surface waters (Ref. 6390). Trawl catch rates for warty oreos, and for oreos in general, show no evidence of vertical migration during day or night (Ref. 27150), even though many of the planktonic species consumed by this species undergo daily migrations within the water column (Ref. 6390).
