Etymology: Bathyagonus: Greek, bathys = deep + Greek, gonos, gone = birth (Ref. 45335). More on author: Gilbert.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 110 - 910 m (Ref. 28197). Subtropical; 61°N - 31°N, 165°W - 115°W (Ref. 57306)
North Pacific: Gulf of Alaska to southern California, USA. Evermann and Goldsborough 1907 (Ref. 11366) erroneously recorded Bathyagonus pentacanthus from the Bering Sea.

Estimates based on models
Preferred temperature (Ref. 115969
): 4.7 - 7.9, mean 5.9 °C (based on 32 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5625 [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. 93245
Trophic level (Ref. 69278
): 3.2 ±0.4 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
): Low to moderate vulnerability (33 of 100) .
