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); mirabilis: Latin for wonderful or strange, allusion not explained, possibly referring to its large eyes and/or typically strange chimaeroid appearance (See ETYFish).
