Cannibalistic morph individuals differ from typical morphs by their enlarged vomerine teeth, wider heads, long slender bodies, and tendency to consume conspecifics (Powers, 1907; Rose and Armentrout, 1976; Lannoo and Bachman, 1984).

Vomerine teeth in two small oblique groups, are closer to each other than to choanae.
As ma- jority of patients in current study belonged to younger age group the frequently encountered fracture type was also found to be sagittal fracture.22 In contrast the para sagittal split is encountered in older adults as the bone lateral to vomerine attachment of maxilla is thin.
Nevertheless, some catfishes such as Clarias isheriensis was reported to have inherent amylase and cellulase which might also assist the fish to digest cellulose cell wall while the gridding of the diets between the vomerine teeth exposes the lignin and/or cell wall by increasing the surface area to digestion (24), (25).
