Etymology: Chimaera: Latin, chimaera = marine monster, 1634 (Ref. 45335);  opalescens: Name from the Latin opalus (opal), refers to the characteristic iridescent colouration of the fresh specimens, resembling the nacreous colours of the semi-precious stone opal.

简单描述 型态特徵 | 形态测量图

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).
