Huran Sandworms

Huran Sandworms are large subterranean creatures found exclusively on Hura IV. Their existence was thought to have been historic until 2410 when an archaeological expedition was killed by one or more of the creatures. The crew of the USS Hunt was sent to investigate the disappearance of the team, and three of its senior crew were stranded on the planet for two days with the creatures lying in wait before being rescued.
