Adult Peacock Razorfish are grey dorsally, yellow-white ventrally, have three broad indistinct bars laterally, and a blue-rimmed black spot on the upper side of the body.
The colouration of juveniles (see image) is variable. They usually have more distinct dark bars than the adults and often have two spots on the soft dorsal fin.
This species lives over sand near coral reefs. When disturbed it uses its keeled forehead to dive headfirst into the sand.
Juveniles appear to mimic dead drifting leaves. They often hold the first two dorsal spines forward over the head.
The Peacock Razorfish grows to 35cm in length. It is known from north-western Australia and from northern Queensland to southern New South Wales.
