Prionurus biafrensis has a deep, oblong and compressed body with its deepest part fitting into its standard length 1.8 times. The snout is distinct as there is a clear indent of the dorsal profile between the maxilla and the upper edge of the orbit. The dorsal profile of the head then climbs steeply to the origin of the dorsal fin before curving regularly downwards to the caudal peduncle. The ventral profile is less strongly curved. The dorsal fin is supported by 8 spines and 25 soft rays, with a clear notch between the spiny and soft rayed parts, and the anal fin contains 3 spines 24 soft rays [6] The head is marked with 2 pale bars and there are 3 spines in the grooves on either side of the caudal peduncle. [7] The maximum published total length of the Biafran doctorfish is 20 cm (7.9 in), although 15 cm (5.9 in) is more common. [2]
