The omnivorous freshwater loach, Lepidocephalichthys guntea (Hamilton, 1822) inhibiting unique ecological niche where oxygen content is low. Its alimentary canal is remarkably short. The mucosal adaptation of the intestine in adult L. guntea with respective digestive - as well as respiratory function was studied. The surface design of the mucosa of different sections (anterior, mid, and posterior) of the intestine of L. guntea were analysed using light and scanning electron microscope following commonly accepted procedures. The mucosa of the anterior intestine was provided with various types of mucosal folds and crowded with almost closely oval or rounded columnar epithelial cells with prominent microridges. Various cellular elements in the anterior and mid intestine were accordingly adapted to serve the important functions of absorption and gas exchange. The posterior intestine is probably adapted to suit its role for aerial respiration
