The Eight Legs were black spiders, generally less than a metre in length, though the Great One was much larger. They relied on human mounts for transport, though they could scuttle along at walking pace. The Eight Legs could create webs like the spiders of Earth, though they were not sticky, merely tough. They fed on the flesh of living creatures, generally the sheep of Metebelis III, though they preferred human meat. (TV: Planet of the Spiders)
