Yellowfin surgeonfish

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.
==Description==
The yellowfin surgeonfish ranges in length to . It has eight or 9 dorsal spines, 25-27 dorsal soft rays, three anal spines, 23-25 anal soft rays, and 16-24 anterior and 17-22 posterior gill rakers.〔
Its body is purplish gray. It has a region of dull yellow in front of its eye. The outer third of its pectoral fin is yellow, the extreme distal part is hyaline. Its dorsal and anal fins are yellowish grey basally and dull yellow distally. Its caudal fin is purplish and the caudal spine is small.〔
