Geonosian hydras preyed upon less defended Geonosian hives. They were sometimes used as the main event in Geonosian gladiatorial fights, where they would be pitted against a large number of armed gladiators.
A Geonosian hydra exoskeleton was displayed inside the Royal Icqui Aquaria, a large, public aquarium that was situated on the planet Coruscant.
