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); owstoni: In honor of Alan Owston (1853‒1915), English businessman, yachtsman, and collector of Asian wildlife, who supplied holotype (See ETYFish).
Eponymy: Alan Owston (1853–1915) was an English businessman who was a collector of Asian wildlife, as well as a yachtsman. [...] (Ref. 128868), visit book page.

Estimates based on models

Preferred temperature (Ref. 123201): 0.2 - 4, mean 2.5 °C (based on 50 cells).

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): 3.7 ±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): High vulnerability (57 of 100).
