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); africanus: -anus (L.), belonging to: Africa, described from deep water off the KwaZulu-Natal South Coast of South Africa. (See ETYFish).
