The rearing spider, also known as the giant cave spider, was a large arachnid native to Endor that got its name from its way of intimidation and attacking, standing on its rear and encompassing its prey with all of its legs. Unlike most spiders, the rearing spider would hunt its prey instead of capturing them in webbing, and it has six legs instead of eight. It could usually be found in desert caves or scavenging the rotten meat left by a Gorax. They were sometimes preyed upon by condor dragons.
Inside the Gorax's cavernous lair they encountered several rearing spiders. A baby spider tries to attack them as they cross a large web stretching across a bottomless pit, but Mace stabs it with a knife, causing it to fall screaming into the pit.
A large one attacks Deej, who was the last one to cross. The Ewok priestess Kaink used her magic scepter to momentarily hypnotize it. Just as the spider came out of its hypnotic trance, the Ewok Chukha-Trok cut a main anchoring strand of the large web the spider was on with his axe. The spider plunged into a deep crevice, screeching to its death.
