The cnidoblasts used during looping movement of Hydra are:
1 stenoteles
2 volvents
3 desmosomes
4 atrichous isorrhiza
Explanation:
D Atrichous isorrhiza is a type of nematocyst present on the tentacles and helps hydra to locomote also known as inchmovement or somersaulting. - In this method of locomotion of hydra usually the body first extends and then bends over, so that the tentacles attach to the substratum with the help of adhesive atrichous isorhiza.

Nematoblast of hydra are:
1 Sensory
2 Complicated
3 With nematocyst apparatus
4 All of the above
Explanation:
A Nematoblasts of cnidoblasts are sensory in nature. Cnidarian Animals are characterized with Cnidoblasts or cnidocytes present on the tentacles and the body. Cnidoblasts are used for anchorage, defense and for the capture of prey. - Cnidaria is classified in the kingdom animalia. They are mostly found in both marine and fresh water environment Examle- Corals, sea anemones, Jellyfish, hydra etc.
