The hydra belongs to the same group of organisms as jellyfish and corals. Most Hydra species have individuals which are either male or female.

Hydra are exceptionally interesting due to their regenerative ability and that they appear not to age or die of old age. Another sessile Hydrozoa is the Hydra which is truely unique among the Hydrozoans. Mollusks that call coral reefs their home include octopi, nautilus and clams. The physical characteristics of coral reefs allow many marine species to call them home.
A hydroid has typically three life-cycle stages. Hydra, the Water Snake, resembles the creature from which its name derives, with it huge body slithering across 100 degrees, and covering 3.158% of the night sky, making it the largest of the 88 recognized constellations. It is very fast and flexible, and new modules are easy to add. Characteristics Physical Description.

The common characteristic to all of these animals is that they have stinging cells located, known as cnidocytes, on their tentacles. Other characteristics: Hydra are exceptionally interesting due to their regenerative ability and that they appear not to age or die of old age. The first stage is a tiny pelagic larva. The Hydra was literally multiple times more ferocious than its closest relative: the snake. This truly complex habitat is home to fish, sponges, eels, jellyfish, sea stars, anemones, crustaceans, snails, turtles and mollusks.

The Hydra is solitary, lacks a medusoid phase and feeds with long tentacles that extend from around the mouth. This phylum also includes animals such as the jellyfish and sea anemone and the organisms that make up coral reefs. Some Interesting Facts: Hydrozoans have many cell types, but form only two tissue types for their bodies, epidermus and gastrodermis. Hydras are simple, multicellular animals that have existed for hundreds of millions of years.
Characteristics: Hydrozoans are small predatory animals. However, they can still die from means other than aging (senescence), such as through injury, disease, starvation, or unsuitable conditions in the habitat.
The first settlers of the island were Mycenaeans and are traced back to ancient times as witnessed by the excavations.
It is the second largest moon of Pluto, being slightly larger than Nix.Hydra was discovered along with Nix by the Pluto Companion Search Team in June 2005. It has a cylindrical body attached to the axis of the hydrocaulus by its proximal end and free at its distal end.
Each polyp is very much like a miniature Hydra.
