Abstract
An unusually patterned surgeonfish representing a likely hybrid of Acanthurus triostegus and A. polyzona was collected and photographed from Mauritius. The specimen possesses an intermediate number of black bars (8) relative to its parent species (6 & 9, respectively), as well as having facial markings showing characteristics of both taxa. This represents the first report of a hybrid for either species
