Spot-nape butterflyfish

The Spot-naped Butterflyfish (''Chaetodon oxycephalus'') is a species of butterflyfish (family Chaetodontidae). It is found in the Indo- West Pacific region from Sri Lanka to Queensland, north to Indonesia and the Philippines.〔 (2008): (''Chaetodon oxycephalus'' ). Version of 2008-JUL-24. Retrieved 2008-SEP-01.〕
It grows to a maximum of long. The body is white with thin vertical lines on the sides and a large black area in the upper back. Very similar to the Lined Butterflyfish (''C. lineolatus''), its vertical black eyestripe is broken above the eye and there are additional black and orange lines and spots in the yellow dorsal and caudal fins.〔
The Spot-naped Butterflyfish belongs to the large subgenus ''Rabdophorus'' which might warrant recognition as a distinct genus. In this group, it seems to be member of a lineage also containing species such as the Lined Butterflyfish, or the peculiar Black-wedged Butterflyfish (''C. falcula'') and Pacific Double-saddle Butterflyfish or "False Falcula" (''C. ulietensis''). These four differ wildly in shape, but all have bluish vertical lines on a white body with yellow behind, and black on back and caudal peduncle in addition to the typical eyestripe of ''Chaetodon''. The Blue-cheeked Butterflyfish (''C. semilarvatus'') seems to be a far more basal lineage of ''Rabdophorus'' relative to them, but it also has the tell-tale blue vertical lines.〔 (2007): Molecular phylogenetics of the butterflyfishes (Chaetodontidae): Taxonomy and biogeography of a global coral reef fish family. ''Mol. Phylogenet. Evol.'' 45(1): 50–68.

''Raffles Bulletin of Zoology Supplement'' 14: 77-86. (PDF fulltext )〕
''C. oxycephalus'' is found in coral-rich areas and clear waters of seaward reefs at 10-40 m depth. It feeds on coral polyps and sea anemones.〔
