Short Description
Original diagnosis after DIDIER, 2008 [3359]: A species of chimaeroid fish assigned to the genus Hydrolagus on the basis of a ventral caudal fin that that is not indented at its origin to form a separate anal fin. Hydrolagus marmoratus is distinguished from its congeners by the following combination of characters: body colour pale brown with prominent reticulations on sides, dorsal fin and spine whitish basally, dorsal-fin spine slightly shorter than or subequal in height of first dorsal fin, pelvic fins somewhat rectangular in shape (not broadly rounded), and males with pelvic claspers that are mostly pale, divided for the distal 2/3 of their length.
