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); mccoskeri: In honor of American ichthyologist John E. McCosker (b. 1945), California Academy of Sciences, who collected and supplied holotype to the authors. (See ETYFish).
