Raccoon Butterflyfish

Chaetodon lunula

Summary & Description 2

The raccoon butterflyfish (Chaetodon lunula), also known as the crescent-masked butterflyfish, lunule butterflyfish, halfmoon butterflyfish, moon butterflyfish, raccoon butterfly, raccoon, raccoon coralfish, and redstriped butterflyfish, is a species of butterflyfish (family Chaetodontidae).
Chaetodon lunula can reach a length of 20 cm (nearly 8 in). These large butterflyfishes have an oval outline, with a pattern of ascending oblique reddish stripes on the flanks and black and white bands over the face and eyes, similar to the raccoon mask (hence the common name). They show a black spot on the caudal peduncle and oblique yellow stripes behind the head. They have 10-14 dorsal spines and 3 anal spines.

Biology 3

Chaetodon lunula is a nocturnal species that usually lives in small groups. Adults feed mainly on nudibranchs and small invertebrates, but also on algae and coral polyps.

Habitat 4

This species prefers seaward reefs and shallow reef flats of lagoon, at a depth of over 30 m.

Distribution 4

This species can be found widely throughout the tropical Indo-Pacific region (East Africa to the Hawaiian and Marquesan islands, north to southern Japan) and in the southeast Atlantic (South Africa).

Notes 5

Juveniles travel via the East Australian Current to Cabbage Tree Bay Aquatic Reserve, and can typically be found when water temperature is over 20 degrees Celsius
