Description
The eight-lined wrasse is reddish to yellowish in colour with around eight thin purplish, horizontal stripes along its flanks, the three stripes top extend onto its head.

Habitat and biology
The eight-lined wrasse is a benthopelagic species which is found among rubble or live corals of seaward reefs, where it prefers areas where there are caves and crevices containing abundant invertebrate growth, They are found down to depths of at least 40 metres (130 ft). It is a carnivorous fish which preys mostly on benthic crustaceans, as well as small molluscs, sea urchins, fish eggs, and crab larvae. This is a solitary, diurnal species which takes shelter in cavities where it creates a mucus cocoon in which to sleep during the night, it is thought that this cocoon helps protect it from nocturnal predators by masking the scent of the sleeping fish.
