Description

Abalistes stellatus has 3 spines and between 25 and 27 soft rays in its dorsal fin while the anal fin has 24 or 24 soft rays. There is an oblique groove in front of the eye and the scales to the rear of the gill slit are large. The depth of the body fits into the standard length between 2 and 2.5 times.

The caudal peduncle is flattened and is at least as wide as it is deep, as well as being narrow and tapering with a length much greater than its depth. The caudal fin is double emarginate and the two lobes lengthen as the fish grows.

The large scales behind the gill slit and above the base of the pectoral fin create a flexible tympanum. The scales towards the rear of the body are keeled, creating longitudinal ridges.

The overall colour is greyish to greenish-brown fading to whitish ventrally, there are four large white blotches along the back, the last of these is located on the caudal peduncle and the body is marked with pale yellowish-brown spots and there may be a white streak on the middle of the upper side.[6] This species has a maximum published total length of 60 cm (24 in), although 40 cm (16 in)is more typical.

Abalistes stellatus has a wide distribution in the Indian and Western Pacific Oceans.

It occurs along the coast of eastern Africa from the Red Sea to Mossel Bay in the Western Cape, South Africa, across the Indian Ocean and into the Western Pacific Ocean as far east as Fiji, north as far as southern Japan and south to northern and eastern Australia.

It is found at deptsh between 4 and 120 m (13 and 394 ft) in areas of sand, sponge, and seaweed areas over deep slopes. The juveniles frequently inhabit sheltered coastal bays and estuaries where there are open areas scattered with outcrops of rubble and other debris.
