Hydra moves by gliding process to cover very short distances. In this process the hydra moves as slowly as the amoeba. A slippery sap is secreted from the cells of the epidermis of the soles of hydra. It creates a moment from the place of the feet. Momentarily moves forward on smooth ground. At the same time, the Hydra moves forward very slowly. In this way, the hydra very slowly crosses a very small distance.
