Holocéphales (chimères) (chimaeras) > Chimaeriformes (Chimaeras) > Chimaeridae (Shortnose chimaeras or ratfishes)
Etymology: Hydrolagus: hydro-, combining form of hydor (Gr.), water; lagos (Gr.), hare, i.e., “water rabbit,” probably referring to three pairs of tooth plates, which tend to protrude from the mouth like a rabbit’s incisors. (See ETYFish);  homonycteris: homo-, from hominis (L.), man; nykteris (Gr.), bat, referring to Thomas A. Griffiths, bat systematist known as “bat man,” who introduced Didier to chimaeroid fishes. (See ETYFish).

Description synthétique Morphologie | Morphométrie

This chimaeroid fish has a ventral caudal fin that that is not indented at its origin to form a separate anal fin, it is distinguished from its congeners by the following characters: color of the body an even dark black or blackish-brown; its dorsal fin spine is longer than height of first dorsal fin; pelvic fins is distinctly round in shape; males with pelvic claspers that are dark at the base with pale tips, divided for the distal 1/3 of their length (Ref. 76967).
