The white-barred sweetlips Plectorhinchus playfairi, also known as the white-barred rubberlip, is a species of grunt. Closely related to the snappers, grunts have smaller mouths and teeth and thicker fleshy lips hence the name sweetlips. They may also grind their teeth together when caught, emitting a grunting sound, hence the name grunt. The white-barred sweetlips is a common fish on the east African coast and is one of the larger sweetlips.

APPEARANCE

White-barred sweetlips have a dark black upper body and the lower part of the body is silver. They have four white vertical stripes on the body. The fins are all dark  black. As is to be expected from their name, they have large bulbous lips. They grow up to 90cm in length. The fishes in the images photographed in the Mafia Island Marine Park, are roughly this size.
