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).
