琵琶鮫科(Angel sharks) (Angel sharks)
Etymology: Squatina: Latin for skate, which angel sharks superficially resemble, presumably tautonymous with Squalus squatina Linnaeus 1758 (no species mentioned) (See ETYFish); pseudocellata: pseudo-, from pseudes (Gr.), false; ocellata (L.), having little eyes (ocelli), referring to indistinct ocellate markings on pectoral fins (See ETYFish).
