When alive, the Little Gurnard Perch has a mottled brownish body. There is a large black blotch on dorsal fin membrane between the fifth and ninth spines in both males and females. The colour pattern is similar to that of Whitley's Gurnard Perch and Southern Gurnard Perch.
The species can be distinguished from other Australian species of Maxillicosta by the combination of two characters. The scales above the lateral line behind the head lack a strong median ridge or a serrated ridge. The nasal spine has 2 or 3 small points.
The Little Gurnard Perch is common in southern Australian inshore waters, usually in seagrass beds, rubbly areas or on sandy substrates. Individuals bury completely in the sand during the day, but emerge at night.
Although several specimens, collected from central Western Australia, have been identified as M. scabriceps, they may represent a new species and M. scabriceps may only occur between Victoria and southeastern Western Australia.
