Introduction

The Redlip Morwong is commonly seen on shallow rocky reefs off the western Western Australian coastline and less frequently along the southern coastline.

Identification

The species has a pale tan body, with seven brown bars. The pale interspaces are speckled with brown spots and blotches. The fins are also pale with brown spots. The lips are bright red, giving the fish its scientific name rubro meaning red and labiatusreferring to the lips.

Distribution

The species is endemic to Western Australia and can be found from the Recherche Archipelago in the south to Coral bay in the north.

Life history cycle

Like all Cheilodactylids, the Redlip Morwong transforms from its larval stage to what is known as the 'paperfish' stage. During this stage the fish lives a pelagic existence, as opposed to its later demersal life. The body is highly compressed and usually silvery in colour. After the fish settles (finds a suitable home on the reef), the body shape changes to the adult form.
