The Netcaster was a highly dangerous arachnid native to the homeworld of the Wookiees, Kashyyyk. The average length of the netcaster would often be 75 centimeters. They would spin webs among the talls trees of their native environment which would snatch their usual prey, namely the Daubirds. Against attackers or more dangerous predators, the netcaster would use its highly venomous bite to protect itself.
