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); lusitanicus: -icus (L.), belonging to: Lusitania, ancient name of Portugal, where it was initially identified (See ETYFish).
