Short description Identification keys | Morphology | Morphometrics
Dorsal spines (total): 15 - 18; Dorsal soft rays (total): 12 - 13; Anal spines: 0; Anal soft rays: 13 - 14; Vertebrae: 40. Interpelvic process small and bifid. Body naked ventrally behind the long anterior corselet. Dorsal half of body to lateral line covered with scales. Swim bladder absent. The back is bluish, turning to deep purple or almost black on the head; the belly is white, without stripes or spots; the pectoral and pelvic fins purple, their inner sides black.
An occasionally schooling species which feeds mainly on krill (euphausiids), and also on squids and small fishes. Juveniles are found between 20 and 35°S at surface temperatures ranging from 19 to 24°C. Its flesh is paler than that of most true tunas and is very oily, but the cooked meat has fine eating qualities. Mainly marketed fresh.

Estimates based on models
Preferred temperature (Ref. 115969): 15.8 - 24.6, mean 18.4 (based on 182 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00955 (0.00460 - 0.01984), b=3.06 (2.89 - 3.23), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.7 ±0.1 se; based on diet studies.
Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153): High to very high vulnerability (70 of 100).
