Environment: milieu / climate zone / depth range / distribution range
Marine; pelagic-oceanic; non-migratory; depth range 100 - 690 m (Ref. 4479), usually 510 - 550 m (Ref. 96467). Deep-water; 46°N - 27°S, 123°E - 14°E

Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 8 - ? cm
Max length : 9.0 cm SL male/unsexed; (Ref. 4479)
High-oceanic, found between 490-690 m during the day and from 100-200 m at night. Specimens larger than 30 mm are non-migratory (Ref. 4479). Mesopelagic (Ref. 58302). Sexual maturity at a length of 7,5 cm (Ref. 47377). In the Atlantic, gravid females were taken in February and April, suggesting a late summer spawning period (Ref. 96467).

Phylogenetic diversity index (Ref. 82805
= 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.1 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
