School of yellowfin surgeonfish or Cuvier's surgeonfish ( Acanthurus xanthopterus ) in Caribbean Sea - Akumal Bay - Riviera Maya / Cozumel , Quintana Roo , Mexico - HD stock video

The yellowfin surgeonfish or Cuvier's surgeonfish (Acanthurus xanthopterus) is one of several marine fish that change color as they get older. This characteristic confused fish identification, and originally put the young and adults in different species. With the arrival of aquaria and later, coral reef aquaculture, specialists noticed the color transformation. Only recently have zoologists begun to understand their metamorphosis.
