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); affinis: Latin for related, referring to its similarity to Chimaera monstrosa (See ETYFish).

Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie
Lacks a separate anal fin. Pectoral fin does not overlap pelvic fin. Short caudal filament. Dark brown in color (Ref. 6902).
Epibenthic (Ref. 58426). Found on continental slopes and down to deep-sea plains. Reported down up to 3000 m along the mid-Atlantic ridge (Ref. 83979, C.Cotton pers.comm. 03/10). Feeds on small fishes and invertebrates (Ref. 6680). Oviparous (Ref. 205). Eggs are encased in horny shells (Ref. 205). It is commercially used as fish meal and to produce high-quality machine oil from the liver (Ref. 117245).

Estimates based on models
Preferred temperature (Ref. 123201): 3.3 - 4.3, mean 3.5 °C (based on 57 cells).
Fylogenetische diversiteitsindex (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).
Trofisch niveau (Ref. 69278): 4.3 ±0.41 se; based on food items.
Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Assuming Fec <100).
Fishing Vulnerability (Ref. 59153): Very high vulnerability (78 of 100).
Nutrients (Ref. 124155): Calcium = 8.44 [2.45, 28.17] mg/100g; Iron = 0.345 [0.115, 0.914] mg/100g; Protein = 16.1 [10.5, 19.1] %; Omega3 = 0.299 [0.107, 0.829] g/100g; Selenium = 23.6 [7.3, 77.0] μg/100g; VitaminA = 5.7 [1.2, 25.5] μg/100g; Zinc = 0.265 [0.133, 0.516] mg/100g (wet weight); based on nutrient studies.
