Spice spider

Spice spiders were members of a species of spider that could be found on Aaloth, Taul, and allegedly on Kessel. Their webs were pure glitterstim. At some point prior to the Battle of Takodana, a group of droids stranded on Taul were ambushed by a swarm of spice spiders. Security droid PZ-99 then sacrificed himself to save the rest of the droids, of which only one would make it off the planet. According to Fugas Fandita, the spiders in the Spice mines of Kessel were supposedly attracted to light and could sense motion and fed on unwary miners.
