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); alberti: In honor of Norwegian-born American oceanographer Albert E. Parr (1901‒1991), editor of the authors’ “Fishes of the Western North Atlantic” monographs, for his many contributions to ichthyology (See ETYFish).
Eponymy: Dr Albert Eide Parr (1890–1991) was an oceanographer and marine biologist who was born and raised in Norway, where he took his first degree at the University of Oslo. [...] (Ref. 128868), visit book page.
