Etymology: Allocyttus: Greek, allos = other + Greek, kyttaros, kytos = a convex cavity.
Ambiente: milieu / zona climática / intervalo de profundidade / gama de distribuição
Ecologia
marinhas batipelágico; oceanódromo (Ref. 51243); intervalo de profundidade 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).
Comprimento na primeira maturidade / Tamanho / Peso / Idade
Maturidade: Lm 28.0, range 23 - ? cm
Max length : 42.5 cm TL macho/indeterminado; (Ref. 27159); peso máx. Publicado: 2.0 kg (Ref. 27124); Idade máx. registada: 140 anos (Ref. 39383)
Espinhos dorsais (total) : 5 - 8; Raios dorsais moles (total) : 28 - 33; Espinhos anais: 2 - 3; Raios anais moles: 26 - 31. Adults blackish black in color; prejuveniles silvery, back greenish with large grey blotches that disappears at about 12 cm (Ref. 6548).
Body shape (shape guide): short and / or deep; Cross section: angular.
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).
