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); trolli: In honor of American artist Ray Troll (b. 1954), Ketchikan, Alaska (USA), “one of the few true chimaeroid lovers of the world ... for his valiant efforts to increase ratfish awareness worldwide” (See ETYFish).
Eponymy: Dr Raymond ‘Ray’ Michael Troll (d: 1954) is an American artist (he calls himself a “fin artist”), musician, humourist and illustrator. [...] (Ref. 128868), visit book page.
