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); eidolon: Greek for a phantom double, referring to its similarity to H. purpurescens, with which it had been confused. (See ETYFish).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 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): 3.9 ±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.
