Description

The rock wrasse is a wrasse of the family Labridae from the eastern Pacific. The species grows to about 38 cm; females are brownish, while large males show a blue-green body with a conspicuous orange-yellow band behind the head. It lives close to rocks near sand patches and in tide pools. When threatened or at night it dives into the sand in a flash to shelter or rest. As a bottom predator it feeds on crustaceans, molluscs, sea urchins and polychaete worms. Like many wrasses it is a protogynous hermaphrodite: it begins as a female and the largest individuals become males. The species is harmless to humans.
