Abstract

The morphology and histology of the alimentary tract of Garra tibanica is described. Specializations in the form of the esophageo-intestinal sphincter, the intestinal swelling and the intestinal looping are reported. The histological features of the esophageal lining are characterized by ciliated columnar epithelium intermingled with goblet cells. Minor histological changes occur at the esophageo- intestinal sphincter, at the intestinal swelling and intestinal looping and the the distal intestine; otherwise, the intestinal lining is much the same throughout. The chief difference is in the degree o complexity and depth of folding. Neither a basement membrane nor a stratum compactum are evident.
