Due to confusion with relatives it is poorly known, but it likely reaches at least 2 m (6.6 ft) in length.[3] Its upperparts are greyish or brownish with 4–5 rows of white spots along each side; above each pectoral fin there is a dark spot surrounded by several smaller white spots.[3] Except for its denser white spotting, it closely resembles the eyebrow wedgefish (R. palpebratus), but their ranges do not overlap.[3]
