Etymology: Chimaera: Named for the mythological creature composed of parts of multiple animals, referring to their odd mix of characteristics. (See ETYFish); ogilbyi: In honor of Irish ichthyologist-herpetologist James Douglas Ogilby (1853‒1925), Australian Museum (Sydney), for his researches on Australian fishes. (See ETYFish).

= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00309 (0.00126 - 0.00759), b=3.11 (2.90 - 3.32), 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 (62 of 100).
