Abstract: The digestive tract histology of the false upside down catfish (Synodontis nigrita) was investigated to fill knowledge gap and provide data for further studies. The jaws were lined by stratified squamous epithelium containing eosinophilic club cells, mucous cells and lymphocytes. This epithelial covering may be related to protective function from pathogens and predators. The oesophagus presented abundant mucous cells in stratified squamous epithelium. These mucous cells help lubricate the tract during passage for food materials as the teleost lack salivary glands. The stomach was lined by simple columnar cells containing intra-epithelial lmphocytes which contribute to local immune response. The intestine was sacculated and mucosa was lined by simple columnar epithelium containing abundant goblet cells and lymphocytes. An intestine-rectal valve separated the rectum from the intestine. In conclusion, the digestive tract of the false upside down catfish (Synodontis nigrita) is adaptive to its feeding and lifestyle in the aquatic wild environment.
