Introduction

The Whitebarred Boxfish has a distinctly hump-backed appearance. The species occurs in coastal southern Australian waters.

Identification

The Whitebarred Boxfish is encased in a rigid bony carapace. It has a deep body with keel-like ridges on the upper and lower margins. The eyes are small and placed high on the head. The snout is concave.

Males and females look different. Females and juveniles are orange with black and white blotches and lines. Males are bright orange with distinct white bands. One band passes from the eye to the mouth. A second band passes from the top of the hump on the fish's back, in front of the pectoral fin and back towards the belly. A third band crosses the body in front of the dorsal and anal fins. A fourth band encircles the caudal peduncle.
