Same as a jellyfish. It's prey is killed or paralyzed by the nematocysts on its tentacles. The tentacles then move the prey to its mouth.

It lives on soil or in water???
Jellyfish..as example...lives in water !!
Scientists have located jellyfish as deep as 9000 metres, but it is believed that they may exist even deeper than that. This is typical of the Deep-sea jellyfish, which is a member of the Coronate family.

a minute freshwater coelenterate with a stalk-like tubular body and a ring of tentacles around the mouth.
Although hydra are fairly simple animals, the stinging cells which they use to catch their prey are quite complex structures. They have a number of different types of stinging cells, called nematocysts, on their tentacles. ... A second kind of nematocyst, which may have barbs or spines on it, is also fired into the prey.
