生態学
海 深海浮遊性; 海洋回遊性 (Ref. 51243); 深さの範囲 0 - 1800 m (Ref. 50610), usually 800 - 1200 m (Ref. 6545). Deep-water; 28°N - 58°S
Eastern Atlantic: off Mauritania, Gulf of Guinea, Namibia and South Africa. Western Atlantic: off Suriname, southern Brazil and Uruguay. Western Indian Ocean: Mozambique Channel, Walters Bank. Eastern Indian Ocean: East Indian and West Australian Ridge, Australia. South Pacific: New Zealand and off Chile. Records from the North Pacific belong to Allocyttus folletti. Also Ref. 26139).
Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm 28.0, range 23 - ? cm
Max length : 42.5 cm TL オス/雌雄の選別がない; (Ref. 27159); 最大公表体重: 2.0 kg (Ref. 27124); 最大記録サイズ: 140 年 (Ref. 39383)
背面の脊椎 (合計) : 5 - 8; 背鰭 (合計) : 28 - 33; 肛門の骨: 2 - 3; 臀鰭: 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).
