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 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. 115969): 3.3 - 4.3, mean 3.5 (based on 57 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00282 (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): 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).
