Reported from off the Cape, South Africa and from 43°17'S, 48°55'E (Ref. 4066).

Biology     Glossary (e.g. epibenthic)

Oceanic and mesopelagic, found in the upper 100 m south of the Antarctic Polar Front but deeper northwards (Ref. 4066). Adults take more euphausiids and also prey upon polychaetes. The diet of juveniles of less than 6 cm SL consists mainly of copepods, with some euphausiids and hyperiids. Possibly the most common myctophid occurring south of the Antarctic Polar Front.

Estimates based on models

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00851 (0.00473 - 0.01530), b=3.07 (2.91 - 3.23), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level
(Ref. 69278) 		3.2   ±0.4 se; based on diet studies.
Generation time 6.5 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience
(Ref. 120179) 		Medium, minimum population doubling time 1.4 - 4.4 years (K=0.17-0.25; tmax=11).
Fishing Vulnerability
(Ref. 59153) 		Moderate vulnerability (41 of 100). 🛈
Nutrients
(Ref. 124155) 		Calcium = 63.5 [23.8, 202.8] mg/100g; Iron = 0.649 [0.225, 1.681] mg/100g; Protein = 15.4 [13.5, 17.5] %; Omega3 = 0.92 [0.39, 2.31] g/100g; Selenium = 13.9 [4.6, 38.8] μg/100g; VitaminA = 49.6 [8.9, 301.0] μg/100g; Zinc = 0.657 [0.347, 1.130] mg/100g (wet weight); based on nutrient studies.
