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);  novaezealandiae: novus (L.), new, i.e., of New Zealand, in whose waters it occurs. (See ETYFish).
