Max length : 24.7 cm SL самец/пол неопределен; (Ref. 9791)
колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 29 - 37; колючие лучи анального плавника: 0; членистые (мягкие) лучи анального плавника: 26 - 34; позвонки: 47 - 53.
Normal diurnal distribution is between 700 and 1200 m The shallowest diurnal capture (500-600 m) is of one of the smallest specimens (4.3 cm) and the deepest (1500-1600 m) is of one of the largest (20.4 cm), indicating a trend for the diurnal depth to increase with increasing size (Ref. 9791). Nocturnal distribution is between 110-700 m (Ref. 9791). Feeds on decapods and euphausiids (Ref. 6715). Minimum depth from Ref. 58018.

Estimates based on models
Preferred temperature (Ref.
123201): 4.9 - 13.9, mean 8.1 °C (based on 1132 cells).
Phylogenetic diversity index (Ref.

50 = 1.0000 [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), in cm total length, based on all LWR estimates for this body shape (Ref.

Generation time: 1.6 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
устойчивость к внешним воздействиям (Ref.
