Marine; bathypelagic; oceanodromous (Ref. 51243).   Deep-water; 21°S -

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

Circumglobal from the Subtropical Convergence to south of the Antarctic Polar Front at Weddell-Scotia confluence and northern reaches of Ross Sea, and extending northwards to 21°S in meridional currents.

Length at first maturity / Size / Weight / Age

Maturity: Lm ?, range 13 - ? cm
Max length : 16.2 cm SL male/unsexed; (Ref. 5182)

Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 13-16; Anal spines: 0; Anal soft rays: 15 - 19; Vertebrae: 36 - 38. 14-16 AO photophores; 9-12 tooth patches on the lower limb of the second gill arch; 34-38 lateral line organs (Ref. 36121). Pectoral fins relatively long and well developed in juveniles (easily visible in individuals up to about 6 cm SL), progressively becoming relatively shorter, with thicker rays, and covered by skin (in various stages of becoming vestigial between 5-8 cm SL). Adults (greater than 8 cm SL) with vestigial rays buried in skin and not externally visible unless skin abraded or otherwise torn (Ref. 36121).

Biology     Glossary (e.g. epibenthic)

Oceanic (Ref. 4479) and mesopelagic (Ref. 75154). Usually found below 500 m at night but shallower in upwelling regions.

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 0.5 - 3.4, mean 2.4 (based on 1426 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00250 - 0.01151), b=3.08 (2.89 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate vulnerability (40 of 100) .
