🐟 Physical Description

Diagnosis: Petrocephalus valentini is distinguished from all other Petrocephalus species in Central Africa by the following combination of characteristics: dorsal fin with 19-24 branched rays; anal fin with 24-26 branched rays; eye large, the ratio head length and eye-diameter between 2.9 and 3.2; mouth very small, the ratio head length and mouth width between 4.7 and 5.8; 12 teeth or fewer in the upper jaw; and 17 teeth or fewer in the lower jaw . Pigmentation pattern subtle, including two components: (1) a pale dorsal black mark on each side of the body below the anterior base of the dorsal fin, under the second to sixth dorsal rays; (2) an ovoid mark, sometimes scarcely visible, at the base of the caudal fin, extending weakly onto the upper and lower lobes of the fin . : fusiform / normal.
