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);  trolli: In honor of American artist Ray Troll (b. 1954), Ketchikan, Alaska (USA), “one of the few true chimaeroid lovers of the world ... for his valiant efforts to increase ratfish awareness worldwide”. (See ETYFish).

Short description Claves de identificación | Morfología | Morfometría

Body blue-gray with a dark line around the orbit and dark shadowing along edges of lateral-line canals. Snout pointed. Preopercular and oral lateral-line canals sharing a common branch. D1 concave with pale margin. Males with frontal tenaculum deeply curved, upturned distally with spines along dorsal upturned edge. Prepelvic tenacula deeply indented along distal margin. Pelvic claspers with pale fleshy distal lobes, divided distally for 1/3 their length, tips usually extending beyond distal edge of pelvic fins. Ventral caudal fin not deeply indented at its origin to form a separate anal fin.

Estimates based on models

Preferred temperature (Ref. 115969): 3.4 - 6.9, mean 4.8 (based on 322 cells).
Phylogenetic diversity index (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).
Nivel trófico (Ref. 69278):  4.0   ±0.6 se; based on size and trophs of closest relatives
Resiliencia (Ref. 120179):  Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Assuming Fec <100).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (72 of 100).
