Short description
Morfologi | Morfometri
Mjukstrålar i ryggfenan (totalt): 5-7; Mjukstrålar i analfenan: 6. Metamorphosed females distinguished by the following characteristics: length of illicium 134-354% SL; four or five pairs of large, distal escal filaments; 30-50 proximal filaments centered on an anterior margin of escal bulb; absence of escal papillae; relatively short dentary teeth (longest 2.3% SL), arranged posteriorly on four longitudinal series; second and seventh caudal fin rays extremely long (30-47 and 54-76% SL respectively); males unknown (Ref. 86949).

Estimates based on models
Preferred temperature (Ref.
123201): 2 - 7.4, mean 5.5 °C (based on 182 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [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).
Trofisk nivå (Ref.
