Description

The tubelip wrasse is a wrasse from the Indo-Pacific, from East Africa to Micronesia and Samoa. The species grows to about 18 cm and has thick, fleshy lips that form a tube when the mouth is closed, from which it takes its name. Juveniles are brownish with blue-white stripes, males more vividly coloured. With those tube lips it sucks mucus and polyps from corals, especially staghorn Acropora. Like other wrasses it is a protogynous hermaphrodite. The fish is harmless to humans and is assessed as Least Concern (LC) by the IUCN.
