Tricuniculus

"Kleptothule, being a very elongated trilobite, had this trick up its sleeve eventually. This descendant has the ability to dig underground in loose soil and sediment, and has a mouthpart specialized to attacking the "wider" Trilobites from underneath. It then sucks out the inside, leaving only the shell of the prey."

Tricuniculus ("Three Burrows") is a large Gen 1 trilobite. It was submitted to the project November 2nd, 2018. Kleptothule's worm-like shape evolved to actually fit a burrowing lifestyle.

It has a unique method of eating, as mentioned in the official description. Wide trilobites, typically smaller than itself, are all prey, including the smaller Megabyte species. Once the prey is crippled, it sucks out the insides and smaller shelled parts. However, the shell remains as a husk, and these are easy to confuse for live trilobites.

It prefers soft sediment and not getting into the competition of Trilonia Bay, so it stays on the other side of the Trilonia Sea.

Extinction

 * Tricuniculus went extinct November 14th, 2018, due to competition with Opabinia Worm and Imperiumboletus, as it was one of the few creatures able to be controlled.
