Comments: Amphiprion ephippium was originally described as Lutjanus ephippium by Bloch in 1790 in Naturg. Ausl. Fische vol. 4; ref. 469:121, Pl. 250 (fig. 2). East Indies. On p. 98 of Bloch’s Ichthyologie, vol. 7. Valid as Amphiprion ephippium (Allen & Springer 1975). The original specimen was collected at Tranquebar, about 250 km south of Madras, India. Allen suggests this may be an erroneous locality as it is outside the known range.

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 ephippium from the Greek word ephippi, =us, meaning saddle. This species has been commonly referred to as th “Red Saddleback Anemonefish”.
