🐟 Physical Description

Dorsal spines (total): 0; Dorsal soft rays (total): 15 - 22; Anal spines: 0; Anal soft rays: 27 - 32. Diagnosis: Petrocephalus squalostoma is distinguished from all other Petrocephalus species of the Congo province by the following combination of characteristics: body coloration pattern without intense melanin mark, sometimes a faded subdorsal roundish mark present; short dorsal fin with 15-22 branched rays and 27-32 branched rays in the anal fin; more than 13 scale rows between the anterior base of the anal fin and the lateral line; and three distinct electroreceptive rosettes in the head . Body depth 32.9-33.5% of standard length; length of snout to posterior orbital rim of eye 40.9-44.1% of head length; predorsal length 66.7-67.3% of standard length; length of dorsal fin 16.0-17.4% of standard length; preanal length 59.8-60.3% of standard length; distance anterior base of pectoral fin to anterior base of pelvic fin 19.8-20.8% of standard length; caudal peduncle depth 34.6-38.8 of its length . : fusiform / normal.
