Etymology: Allocyttus: Greek, allos = other + Greek, kyttaros, kytos = a convex cavity.
Environnement : milieu / zone climatique / profondeur / gamme de distribution
Écologie
marin bathypélagique; océanodrome (Ref. 51243); profondeur 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).
Longueur à la première maturité / Taille / Poids / Âge
Maturité: Lm 28.0, range 23 - ? cm
Max length : 42.5 cm TL mâle / non sexé; (Ref. 27159); poids max. publié: 2.0 kg (Ref. 27124); âge max. reporté: 140 années (Ref. 39383)
Épines dorsales (Total) : 5 - 8; Rayons mous dorsaux (Total) : 28 - 33; Épines anales: 2 - 3; Rayons mous anaux: 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).
