Classification / Names Nombres comunes | Sinónimos | Catalog of Fishes(Género, Especie) | ITIS | CoL | WoRMS | Cloffa

Elasmobranquios (tiburones y rayas) (sharks and rays) > Squatiniformes (Angel sharks) > Squatinidae (Angel sharks)
Etymology: Squatina: Latin for skate, which angel sharks superficially resemble, presumably tautonymous with Squalus squatina Linnaeus 1758 (no species mentioned). (See ETYFish);  dumeril: In honor of French zoologist André Marie Constant Duméril (1774-1860) “in testimony of [Lesueur’s] remembrance and esteem” (not in honor of Duméril’s equally famous zoologist son Auguste, born in 1812) [presumably a noun in apposition, without the patronymic “i”]. (See ETYFish).
