Identification

The Southern Gurnard Perch has a relatively shallow body that becomes increasingly compressed posteriorly. It has a large, slightly oblique mouth. Specimens photographed at night have three dark blotches or saddles on the back, a black blotch on the dorsal fin and pale brown spots on the caudal fin.

The Southern Gurnard Perch has previously been confused with Whitley’s Gurnard Perch, Maxillicosta whitleyi. The species have different caudal fin markings (in preserved specimens) and nasal spine morphology. For additional differences, see Motomura et al (2006).
