duri punggung lunak (Keseluruhan (total)) : 10 - 11; Sirip dubur lunak: 8 - 9; vertebrata, bertulang belakang: 46 - 47. Body deep. Short pectoral fins, long ventral fins. Relatively large head and absence of ventral light organs. Line of dark chromatophores along the body below lateral line (Ref. 37473).
Oceanic and mesopelagic species (Ref. 6686). Taken regularly at depths shallower than 458 m, with scientific deep-sea fishing gear. Feed mainly on small crustaceans, particularly copepods (Ref. 4525). Oviparous, with planktonic larvae (Ref. 35626) and eggs (Ref. 6686). Paedomorphic (Ref. 35626).

Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00427 (0.00162 - 0.01126), b=3.10 (2.88 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.00 se; based on food items.
Generation time: 2.2 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
