Short Description
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 [13545].

Atlantic Ocean: North-eastern Atlantic, along the slope to the west of the British Isles and France [13545]. Source:
