| Abstract | ||||
| Gastrodiscus aegyptiacus has a disc-like body connected with anterior cone-like part. The oral aperture is terminal and surrounded by numerous dome-shaped papillae, each papilla has 3-15 secondary micro-papillae locale at its apical surface. The cone-like part is fo!ded and carries dome-shaped papillae at its anterior third. The dorsal surface of the body carries transverse folding, while the ventral surface is completely covered by large cauliflower-like papillae. These papillae have complex corrugated apical surface with numerous micro-papillae. Some papillae have concave or depressed apical surface encircled by elevated margin. | ||||
