Ornate wrasse (Lat. Thalassoma pavo). It lives on rocky beds with growths of algae and marine meadows, from surface waters to depths of 50 m. It can reach 25 cm (9.8 in) in lenght, though most do not exceed 20 cm (7.9 in). The females are greenish-brown with thin transversal streaks and five transversal blue bands. The males are yellowy-green with the same vertical streaks and a single blue band behind the pectoral fins, often with a red outline. Their heads are partly purplish-red with a blue pattern. It is an aggressive predator. Its diet consists of small molluscs and crustaceans and the juveniles will act as cleaner fish, feeding on the ectoparasites taken off the skin of other fishes. They are sequential hermaphrodites: there is sexual transformation from female to male, which involves a change of colour.
