Summary:
The name Bodianus vulpinus was incorrectly applied to the Foxfish in many early field guides, a pigfish that is probably more prominent in coastal waters of Western Australia. The true Western Pigfish was long thought to be the same as the Eastern Pigfish, but the two are separable by details of the colour pattern.

Terminal-phase adults red dorsally, white laterally and ventrally, head abruptly white below level of mouth; dorsal surface of head with two transverse yellow bands connecting eyes, first anteriorly across snout, second dorsally.  Dorsal fin red anteriorly yellow on anterior half of soft rayed portion and transparent posteriorly; large black spot ocellated with blue between sixth to tenth dorsal-fin spines.  Anal fin yellow with white basal margin.  Caudal fin red, suffused with yellow especially on uppermost and lowermost segmented rays.  Pectoral fin reddish dorsally with grey blotch at tip.  Pelvic fin white with yellow leading edge.

Similar Species

The Bodianus vulpinus species complex comprises the western Australian B. vulpinus, the eastern Australian B. unimaculatus, the Japanese B. oxycephalus and the Hawaiian B. bathycapros with non-overlapping distributions. They are separable primarily by colouration.

Etymology

The name vulpinus is from the feminine Latin noun vulpes, "fox", and inus, "pertaining to", perhaps in reference to the elongate fox-like snout in this species.
