A Powder-blue Surgeonfish swims over a coral reef in the Maldives


Acanthurus leucosternon is a marine tropical fish belonging to the family Acanthuridae, or surgeonfishes. Its common names are powder blue tang and powderblue surgeonfish. The fish can reach an average size of 23 cm in length. The body has an oval shape and is compressed laterally. Like other surgeonfishes, Acanthurus leucosternon swims with its pectoral fins. The caudal fin has a crescent shape. The fish has a "surgeon's scalpel," an erected part of the spine located at the base of the tail. Acanthurus leucosternon is found in tropical waters from the Indian Ocean. The species inhabits shallow and clear coastal waters always associated with a reef. It prefers flat top reefs and areas along seaward slopes.
