The Bluehead wrasse (Thalassoma bifasciatum) is a saltwater fish of the family Labridae that grows up to 25 cm.
Description
The bluehead wrasse is a small, colourful coral-reef fish of the family Labridae (wrasses) reaching about 25 cm. The colour varies strongly by life stage: young and female fish are yellow or white, sometimes with a dark stripe, while the large 'terminal male' has a bright-blue head separated from the green body by two black bands. Like many wrasses it is a protogynous hermaphrodite: individuals begin as females and may later turn into a dominant male. The species lives near coral reefs and seagrass beds of shallow coastal water in the Caribbean and western Atlantic. It eats zooplankton and small invertebrates; young fish clean parasites off larger fish. It is one of the most studied reef fishes.
