Hydra (genus) Hydra (genus) Hydra is a genus of small, fresh-water organisms of the phylum Cnidaria and class Hydrozoa. They are native to the temperate and tropical regions. Biologists are especially interested in "Hydra" because of their regenerative ability — they do not appear to die of old age, or indeed to age at all. "Hydra" has a tubular, radially symmetric body up to long when extended, secured by a simple adhesive foot called the basal disc. Gland cells in the basal disc secrete a sticky fluid that accounts for its adhesive properties. At the free end of the body is a
