Bakugan Official Handbook
Ouch! The sharp spikes on Limulus's back are very sharp-better not touch. That's not all this Bakugan has going for it. Limulus's entire body is cover in heavy-duty armor that's tough to crack.
Bakugan: Ultimate Handbook
Limulus looks like a trilobite, an extinct sea creature with a round shell covering its body. But Limulus is a Bakugan, so it's built to attack its foes. The sharp spikes on its back keeps enemies at bay. Limulus can use the two tentacles that extend from its mouth to capture its opponents. Then it steals the strength from its enemies to make itself more powerful.
A group of them were seen swimming in New Vestroia in Return to New Vestroia.
