Actinopteri (ray-finned fishes) > Argentiniformes
(Marine smelts) > Bathylagidae
Etymology: Pseudobathylagus: Greek, pseudes = false + Greek, bathys = the bottom of the sea + Greek, lagos = hare (Ref. 45335); milleri: Named after Walter Miller, professor from Stanford University (Ref. 6885) More on authors: Jordan & Gilbert.

Estimates based on models
Preferred temperature (Ref. 115969
): 1.6 - 2.5, mean 1.8 °C (based on 1197 cells).
Phylogenetic diversity index (Ref. 82805
= 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00776 (0.00428 - 0.01408), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic level (Ref. 69278
): 4.2 ±0.1 se; based on diet studies.
Generation time: 2.4 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (27 of 100) .
