They retract their tentacles into their body stalk.
The Hydra will retract their tentacles into their body stalk on their substrate response. Every cell in the hydra reacts during this response.
Hydra will retract their tentacles into their body stem when touched. This is a response inherent in the plants from many centuries ago. Hydra do not like to be touched and close to protect themselves.

Hydra or Hydra
The adult hydra attaches to a substrate using its basal disc, which secretes a sticky substance to help it adhere in place. It extends its tentacles to capture and immobilize prey, which it then ingests through its central mouth opening.
The tentacles of a hydra are the most sensitive because they are equipped with specialized cells called cnidocytes, which contain stinging structures called nematocysts. These cells allow the hydra to detect and capture prey, as well as sense changes in its environment. The high concentration of nerve cells in the tentacles enhances their sensitivity, enabling the hydra to respond quickly to stimuli. This adaptation is crucial for both feeding and defense.
