The Geonosian Hydra was a massive, carnivorous bug-like creature that roamed the planet Geonosis and was known for attacking geonosian hives, as seen in this image. Many hydras were known to live near the Ebon Sea, one of the only seas on Geonosis, which meant that the species was rare. Only one known hydra was killed, and its exoskeleton was displayed on the Republic Capital world, Coruscant.
