Introduction

The Masked Rabbitfish is a predominantly yellow coloured fish with a dark band passing through the eye. It is found in tropical marine waters.

Identification

The Masked Rabbitfish can be recognised by its distinctive colouration. The body is yellow dorsally grading through pale blue to white below. It is covered with wavy blue lines that are vertical anteriorly and horizontal posteriorly. The lines are replaced by blue spots ventrally. A dark band passes diagonally through the eye from the chin to the nape. Above the eye, the band is broken into black spots. The fins are yellow.

Trumpetfish are known to sometimes swim close to different species of fish. Presumably following herbivorous fishes such as these Masked Rabbitfish allows Trumpetfish to more easily approach potential prey without detection. Image: Erik Schlögl
