Description
Petrocephalus congicus is distinguished by its unique combination of morphological features. It has a dorsal fin with 18-19 branched rays and an anal fin with 27-28 branched rays. The fish has a large eye, with the ratio of head length to eye diameter ranging between 3.2 and 3.51. The mouth is large, with the ratio of head length to mouth width between 2.0 and 3.7. Additionally, it has 15-21 teeth in the upper jaw and 24-30 teeth in the lower jaw. The pigmentation pattern includes two distinctive melanin markings: a distinct ovoid mark below the anterior base of the dorsal fin and a crescent-like mark at the base of the caudal fin.
Range & habitat
Petrocephalus congicus is found in the Congo River basin, specifically in the middle Congo River, upper Lomami River, and lower Lualaba River in the Democratic Republic of the Congo. It inhabits freshwater environments and is benthopelagic, meaning it lives near the bottom of the water body.
