Chaetodon auripes, the oriental butterflyfish, is a species of marine ray-finned fish, a butterflyfish belonging to the family Chaetodontidae. It is found in the western Pacific Ocean off Eastern Asia.

Description

[edit]

Chaetodon auripes has a mainly yellow body marked with a wide vertical band running through the eyes which is black with a slightly thinner white band immediately behind that. The juveniles have a black ocellus on the upper part of soft-rayed part of the dorsal fin. This fades as the fish matures. The dorsal, anal and pelvic fins are all vivid yellow in colour.[3] The dorsal fin has 12 spines and 23-24 soft rays while the anal fin has 3 spines and 18-19 soft rays. This species reaches a total length of 20 centimetres (7.9 in).[2]

Distribution

[edit]

Chaetodon auripes is found in the western Pacific Ocean from southern Japan, the Ryukyu Islands, Izu Islands, Ogasawara Islands, the southwest of the Republic of Korea, Taiwan the southern coast of China to southern Vietnam.[1]

Habitat and biology

[edit]

Chaetodon auripes occurs at depths of 1 to 30 metres (3.3 to 98.4 ft) and is found on rocky reefs where coral and algae are present. Juveniles are typically found in tidal pools and sheltered rocky areas in shallow water. They gather in aggregations although they are also often encountered as solitary individuals. This species lives in cooler waters than other butterflyfish and can tolerate temperatures down to 10 °C (50 °F) off Japan.[1] It is known to occur as deep as 150 metres (490 ft). It feeds on filamentous algae as well as worms, crustaceans, soft corals, stony corals, sea anemones, and some other benthic invertebrates.[3]

Systematics

[edit]

Chaetodon auripes was first formally described in 1901 by the American ichthyologists David Starr Jordan and John Otterbein Snyder with the type locality given as Nagasaki.[4] This species belongs to the large subgenus Rabdophorus which might warrant recognition as a distinct genus. [5][6]

Utilisation

[edit]

This species is rare in the aquarium trade.[1]
