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); bemisi: In honor of ichthyologist William E. Bemis, now at Cornell University, “longtime mentor and friend, and a leader in ichthyological research” (See ETYFish).
Eponymy: Dr William E Bemis is a vertebrate anatomist, currently Professor of Ecology and Evolutionary Biology at Cornell University, the university that awarded his first degree (1976). [...] (Ref. 128868), visit book page.
