Spiderians

Spiderians are a species of sentient spiders native to Tarantulon 6. A newscast at the beginning of "Three Hundred Big Boys" tells of their defeat by Zapp Brannigan and the Earth army. As a result, their vast silk resources are plundered by Earth, and every citizen receives a $300 tax rebate.

Trivia

 * The Spiderians seem to have 3 types of resources: silk murals (one of which was priced at $1 billion), elaborate webs with jewels woven into them, and fancy gowns with eight arms.
 * According to Dr. Ben Beeler, the Spiderians are more closely related to Earth elephants than Earth spiders.
 * According to Zapp Brannigan, they taste like crab.
 * They are likely inspired by Star Trek's s, who were also reminiscent of a spider and were linked to some form of silk.
