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);  marmoratus: Latin for marbled, referring to marbled pattern of greyish brown reticulations on sides. (See ETYFish).

Korte beschrijving Morfologie | Morfometrie

This chimaeroid fish has a ventral caudal fin that that is not indented at its origin to form a separate anal fin and is distinguished from its congeners by the following characters: color of body pale brown with prominent reticulations on sides, dorsal fin and spine whitish basally; the dorsal-fin spine is slightly shorter than or subequal in height of first dorsal fin, while the pelvic fins somewhat rectangular in shape (not broadly rounded); pelvic claspers of males are mostly pale, divided for the distal 2/3 of their length (Ref. 76967).

Estimates based on models

Preferred temperature (Ref. 123201): 5.1 - 8.6, mean 6.8 °C (based on 133 cells).
Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00282 (0.00118 - 0.00673), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.9   ±0.6 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref. 120179):  laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Deepwater species with few large eggs.).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (52 of 100).
