Comments: Amphiprion ocellaris was also described by Cuvier, 1830 as Amphiprion melanurus, which was validated by Allen in 1991 as a synonym of A. ocellaris. In 1873 Castenlau described Amphiprion bicolor, which was also listed as a synonym of A. ocellaris by Allen in 1991.

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 andris 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).
