They don't move because they do not have a medusoid stage of life cycle. They expel their gametes into the environment to form a another polyp when eggs are fertilized through a planular larva
Burrowing - Hydra typically move by somersaulting or looping, using their tentacles to anchor and propel themselves in freshwater habitats.

No, the freshwater hydra does not have a medusa stage in its life cycle. The hydra belongs to the class Hydrozoa, which typically do not have a medusa stage like other cnidarians such as jellyfish. Instead, hydras reproduce asexually by budding.
Hydra belong to the phylum Cnidaria and the class Hydrozoa.

The largest species of hydra is the Hydra vulgaris. This freshwater cnidarian can grow up to 30 millimeters (about 1.2 inches) in length, depending on environmental conditions. Hydra vulgaris is known for its regenerative abilities and is commonly studied in biological research, particularly in the fields of developmental biology and regeneration.
There is no such thing as a hydra snake. Hydras are small freshwater organisms belonging to the phylum Cnidaria, while snakes are reptiles belonging to the class Reptilia. They are distinct and unrelated species.

Salt kills freshwater hydra primarily through osmosis, where water moves out of the hydra's cells to balance the higher salt concentration in the surrounding environment. This process leads to dehydration and cellular damage, ultimately causing the hydra to lose its turgor pressure and die. Additionally, the salt can disrupt the hydra's internal ionic balance, further contributing to its demise.
The tentacle of a hydra refers to its long, slender appendages that extend from its body. These tentacles are equipped with specialized cells called nematocysts, which allow the hydra to capture prey and defend itself. Typically, hydras are found in freshwater environments, attached to surfaces like rocks or vegetation.
Hydra live in fresh water only like ponds and lakes.
