Holocephali (chimaeras) > Chimaeriformes (Chimaeras) > Chimaeridae (Shortnose chimaeras or ratfishes)
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);  alberti: In honor of Norwegian-born American oceanographer Albert E. Parr (1901‒1991), editor of the authors’ “Fishes of the Western North Atlantic” monographs, for his many contributions to ichthyology. (See ETYFish).

Estimates based on models

Preferred temperature (Ref. 123201): 5.2 - 10.4, mean 6.6 °C (based on 25 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).
Trophic level (Ref. 69278):  3.8   ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Assuming Fec <100).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (46 of 100).
