Introduction

The Min-ifin Parrotfish can be recognised by its colouration and dorsal fin shape. The species occurs in tropical and some warm temperate marine waters of the Western and Central Pacific.

Identification

The Min-ifin Parrotfish can be recognised by its colouration and dorsal fin shape. The spinous dorsal fin and first soft ray are elevated above the remainder of the fin. The caudal fin is rounded with extended lobes in adults. The dental plates are exposed and blue to dark green in both initial and terminal phase individuals.

Colouration changes with growth. Juveniles have a yellow head and a striped to mottled body. Initial phase fish are brown with white spots. Terminal phase fish become green posteriorly. They have two blue-green bars on the chin and spots and lines around the eye and on the operculum.

Distribution

The species occurs in tropical and some warm temperate marine waters of the Western and Central Pacific. In Australia it is known from the northern Great Barrier Reef south to the central coast of New South Wales.
