Original description: Cuvier first described Amphiprion ocellaris in 1830 in Cuvier & Valenciennes 1830:399 in the Hist. Nat. Poiss. V.5 reference 999, from a specimen collected in Sumatra, Indonesia. Validated by Ida in Masuda et al., 1984 and Allen in 1991 as a synonym of A. ocellaris.

Word origin: Amphiprion is from the Greek roots amph, -i, -o, meaning Around, on both sides; double, and -prion which means a saw. The genus ocellaris is confusing; the Latin root o, meaning an egg; cell, –a, -i, meaning a cell; or perhaps ocell, =us, meaning little eye and -ris meaning laughter (little laughing eye?). The synonym melanurus is composed of the Greek roots melan, -o, meaning black; and ur, =a, -o, meaning tail (thus black tail). The synonym bicolor means two colors (bi = two).
