Petrocephalus pulsivertens is a species of weakly electric fish in the family Mormyridae, commonly known as elephantfishes. This species was described in 2010 by Lavoué, Sullivan, and Arnegard.[1]
Petrocephalus pulsivertens is distinguished by its unique combination of morphological features. It has a dorsal fin with at least 25 branched rays and an anal fin with at least 31 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.[1]
Size
This species reaches a length of 75.6 cm (29.8 in).[1]
Habitat
Petrocephalus pulsivertens is found in the Congo River basin, specifically in the middle Congo River basin in Cameroon, Central African Republic, and the Republic of Congo. It inhabits freshwater environments and is benthopelagic, meaning it lives near the bottom of the water body.[1]
