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).
