Holocephali (chimaeras) > Chimaeriformes (Chimaeras) > Chimaeridae (Shortnose chimaeras or ratfishes)
Etymology: Chimaera: Named for the mythological creature composed of parts of multiple animals, referring to their odd mix of characteristics (See ETYFish); didierae: In honor of Dominique A. Didier (b. 1965), Millersville University (Pennsylvania, USA), for her “outstanding” contributions to the systematics of chimaeras (See ETYFish).
Eponymy: Dr Dominique Ann Didier (d: 1965) is an American marine biologist and ichthyologist. [...] (Ref. 128868), visit book page.

Estimates based on models

Phylogenetic diversity index (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).

Trophic level (Ref. 69278): 3.4 ±0.5 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Deep-water species with large eggs and low fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
