Elasmobranchii (sharks and rays) > Squatiniformes
(Angel sharks) > Squatinidae
Etymology: Squatina: Latin for skate, which angel sharks superficially resemble, presumably tautonymous with Squalus squatina Linnaeus 1758 (no species mentioned). (See ETYFish); albipunctata: albus (L.), white; punctatus (L.), spotted, referring to distinctive white-spotted color pattern. (See ETYFish).
