Etymology: Hydrolagus: hydro-, combining form of hydor (Gr.), water; lagos (Gr.), hare, i.e., “water rabbit,” probably referring to three pairs of tooth plates, which tend to protrude from the mouth like a rabbit’s incisors (See ETYFish); purpurescens: Latin for purple-tinged, referring to its purplish or plum color (See ETYFish).

Estimates based on models

Preferred temperature (Ref. 123201): 1.4 - 1.7, mean 1.5 °C (based on 499 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00331 (0.00137 - 0.00798), b=3.07 (2.86 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
栄養段階 (Ref. 69278):  3.9   ±0.6 se; based on size and trophs of closest relatives
回復力 (Ref. 120179):  低い, ４．５年～１４年の倍増期間の最小個体群 (Assuming Fec <100).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (54 of 100).
