Morphol., 31(3):1068-1075, 2013.SUMMARY: The morphology of the gastrointestinal tract of adult Nile perch was described using standard SEM procedures.Investigations revealed the presence of cardiform teeth in the oral cavity, goblet cells and finger print-like microridges on t he hard palateand oesophagus lumenal surface. Elaborate patterns and bacterial cells were observed on the stomach lumenal surface and intensefoldings in the intestinal region. These observations provide a better understanding of the morphology of the gut in Nile perch and howit is suited for its digestive function.KEY WORDS; Gastrointestinal tract; Lates niloticus; Scanning electron microscopy.
