🐟 Physical Description

Dorsal soft rays (total): 78 - 86; Anal soft rays: 53 - 64; Vertebrae: 58 - 61. Diagnosis: Clarias monsembulai can be distinguished from all congeners, with the exception of C. buthupogon, by its exceptionally long maxillary barbels, 60% of standard length or greater, vs. maxillary barbels less than 60% of standard length, usually considerably less . It differs from C. buthupogon in the absence of fine, pale spots over the surface of the body and by an exposed bony surface of the cleithrum reaching 14-20% of head length, vs. cleithrum deeply imbedded in soft tissue with only a narrow bony ridge visible externally . Clarias monsembulai can be further differentiated from C. angolensis, the species with which it shares closest phenotypic similarity, by longer nasal barbels, 37-51% of standard length vs. 22-34%; longer internal mandibular barbels, 29-37% of standard length vs. 16-27%; longer external mandibular barbels, 45-57% of standard length vs. 24-40%; and by the colouration of maxillary barbels which are white or cream-coloured distally over more than half of their length vs. brown or grey over more than half their length .
