Morphology | Morphometrics
This species was assigned to the genus Chimaera based on the presence of an anal fin which is separate from the ventral caudal margin by a notch. It is distinguished from its congeners by a set of characters: uniform blackish brown color with dark bluish streaking and precaudal tail with longitudinal light and dark stripes; dorsal spine when depressed reaches beyond origin of second dorsal fin; large triangular pectoral fins, when depressed reaches just to pelvic-fin origin; caudal fin ventral margin ending very slightly posterior to caudal fin dorsal margin insertion; males with short pelvic claspers that are externally trifid, 12.1-12.3% BDL, not extending past distal tip of pelvic fins, divided for distal one-third of length; distance from anterior base of dorsal fin spine to center of supratemporal canal short, 6.5-14.8% HDL (Ref. 84536).
