The morphology of the farmed African catfish distal intestines and rectum was   investigated. The samples were dissected out and the tissue slices were   passed through graded ethanol, cleared in xylene, embedded in paraffin wax,   sectioned and stained for light microscopy. Grossly, the intestine was   subdivided into proximal, middle, distal and rectal regions based on palpable   thickness and diameter of the regions. No intestino-rectal valve was   observed; hence the rectum was not well defined. The histology revealed the   presence of tunica mucosa of simple columnar cells, lamina propria of   collagen fibres and muscularis mucosae of smooth muscle fibres; submucosa of   loose connective tissues and blood vessels; tunica muscularis of smooth   muscles in an inner circular and outer longitudinal arrangement; and a serosa   in all regions except the rectum and anus that presented tunica adventitia.   The mucosal folds were fingerlike to orange leaf shaped ingrowths into the   lumen on a transverse section. They decreased in complexity and height but   increased in width towards the rectum. The lining epithelium of the   intestinal tract was comprised of the absorptive simple columnar cells   containing goblet cells and intraepithelial lymphocytes. Some rectal simple   columnar epithelium contained supranuclear vacuoles while others contained   non-vacuolated cytoplasm. The goblet cells contained neutral and acid mucins,   and increased in number progressively towards the rectum. The anal tunica   muscularis contained mostly skeletal muscles
