🐟 Physical Description

Diagnosis: Petrocephalus zakoni is distinguished from all other Petrocephalus species in Central Africa by the following combination of characteristics: dorsal fin with 23 or 24 branched rays; anal fin with 27 or 28 branched rays; eye large, the ratio head length and eye-diameter between 3,1 and 3,3; mouth small, the ratio head length and mouth width between 4.4 and 5.0; 10 teeth of fewer in the upper jaw; and 22 teeth or fewer in the lower jaw . It has a unique pigmentation pattern consisting of three well defined black patches: (1) an intense dark mark on each side of the body close to the anterior base of the dorsal fin, often extending onto the first dorsal rays, forming a characteristic saddle across the dorsum; (2) a mark on each side of the body at the base of the pectoral fin; (3) a crescent-shaped mark on each side of the body centered at the base of the caudal fin, extending onto the upper and lower parts of the caudal fin . : fusiform / normal.
