The Sergeant Baker can be recognised by its long tapering body, blotched colouration and its behaviour. The species is commonly observed by divers as it perches on the substrate with its head raised.

Adult males and females are easy to tell apart. Several of the anterior rays of the first dorsal fin are greatly elongated in males, nearly reaching the adipose fin. The elongated dorsal fin rays can be seen in the middle image.
