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);  opalescens: Latin for opalescent, referring to characteristic iridescent coloration of fresh specimens, resembling nacreous colors of the semi-precious stone opal. (See ETYFish).

Short description Morphology | Morphometrics

Chimaera opalescens can be distinguished from its congeners by the following combination of characters: body evenly coloured, iridescent, varying from beige to tan in adults and bronzish in juveniles; unpaired fins brown to purple, uniformly coloured or with pale or whitish edges; iris black; claspers tripartite divided for one third of their length, not extending beyond the pelvic fins in adults; dorsal spine equal or shorter than first dorsal fin; ventral caudal lobe equal or deeper than the dorsal caudal lobe. Comparison of DNA sequences of the CO1 gene with those of related species supported C. opalescens as a distinct species (Ref. 87424).

Estimates based on models

Preferred temperature (Ref. 123201): 7 - 9, mean 8.3 °C (based on 6 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):  3.7   ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (66 of 100).
Nutrients (Ref. 124155):  Calcium = 12.5 [3.9, 36.9] mg/100g; Iron = 0.281 [0.104, 1.093] mg/100g; Protein = 15.3 [10.4, 19.0] %; Omega3 = 0.495 [0.216, 1.141] g/100g; Selenium = 21.7 [5.9, 59.4] μg/100g; VitaminA = 9.21 [2.75, 29.32] μg/100g; Zinc = 0.429 [0.217, 0.804] mg/100g (wet weight);
