The foxface rabbitfish (Siganus vulpinus) belongs to the rabbitfish family (Siganidae) and is sometimes still placed in the obsolete genus Lo. Other common names are foxface or foxface lo, but these properly refer to any of the rabbitfish species once separated in Lo, e.g. the closely related bicolored foxface. The foxface rabbitfish lives throughout the western Pacific, often inhabiting coral reefs.
