Somewhat fleshy lips, covering teeth in both jaws. Fleshy rim of anterior nostril expands dorsoposteriorly to a flap extending to or beyond posterior nostril.

Indo-Pacific: northern Red Sea and South Africa to Easter Island, north to southern Japan, south to Poor Knight's Island in New Zealand and Rottnest Island in Australia. Southeast Atlantic: False Bay, South Africa (Ref. 525).
Found in sheltered bays, harbors and lagoons (Ref. 48636). Inhabits seagrass areas or areas with hard substrates heavy with algal cover. Usually occur in small groups.
