Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 0; Raios dorsais (total) : 0; Raios anais : 13 - 16; Vértebras: 81 - 85. In adults, head depth 21.3-23.2% of lower jaw length; postorbital region 5.0-6.7% SL or 25.5-30% HL (1/3 of HL). Rear edge of gill cover overlaps with the vertical of the middle of the 4th vertebrae. Pectoral fins begin at the vertical of the end of the 4th to beginning of 5th vertebrae. Postadipose distance represents 4.6-5.9% SL (Ref. 31260).
Body shape (shape guide): elongated; Cross section: compressed.
Inhabits the epimesopelagic layer of the southern ocean circumglobally. Only fry and juveniles were observed in subtropical waters; large adults encountered in sub-Antarctic and Antarctic waters. Capable of shedding teeth and reducing gastrointestinal tract prior to spawning. Monocyclic, that is, they die after the first spawning (a reproductive strategy that evolved as a result of the large distance between feeding and spawning areas). Main food is
Notolepis coatsi which are 15-38 cm in length and weighs to 57-90 g (Ref. 31260).
