Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal soft rays: 13 - 16; Vertebrae: 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).

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Southern Ocean: circumglobal (Ref. 31260). Collected from Meteor and Maud rises, in the Lazarev Sea, and near the South Sandwich Islands (Ref. 36355).

Biology     Glossary (e.g. epibenthic)

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).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.5   ±0.80 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Assuming tmax>10).
Vulnerability (Ref. 59153):  High vulnerability (61 of 100) .
Price category (Ref. 80766):   Unknown.
