The process by which hydra moves by creating loops is called looping movement. Hydra exhibits looping movements to cover long distances.
(i) In this process the hydra stands upright on the trajectory by the foot.
(ii) Bends the head forward and touches the trajectory by the Karshika.
(iii) A loop is formed between the sole and the head when the base is touched by the nematocyst of Karshika.
(iv) Then pull the feet closer to the head.
(v) Retouches the trajectory by treading.
(vi) Stands straight again with the head raised on the floor.
(vii) Then moves forward bending the head forward.
By forming a loop like this, the hydra moves forward.
