Classification / Names Noms communs | Synonymes | Catalog of Fishes(Genre, Espèce) | ITIS | CoL | WoRMS | Cloffa

Élasmobranches (requins et raies) (sharks and rays) > Heterodontiformes (Bullhead and horn sharks) > Heterodontidae (Bullhead, horn, or Port Jackson sharks)
Etymology: Heterodontus: heteros (Gr.), different; odontos (Gr.), tooth, referring to pointy teeth (for clutching prey) at front of jaws, different than rounded molar-like teeth (for grinding hard-shelled invertebrates) at the back. (See ETYFish);  ramalheira: In honor of João Ramalheira, captain of the trawler from which holotype was collected, and “who has brought in much valuable scientific material” [presumably a noun in apposition, without the patronymic “i”]. (See ETYFish).
