Siltcrawler
this burrowing creature lived in huge colonies beneath the surface of the planet Nelvaan. They preferred to establish their colonies within the root system of large trees, which offered them easy access to nutrients as well as protection. However, siltcrawlers were the favored prey of the horax, which used the large horns on its snout to unroot trees and expose the colony. A single horax could consume an entire siltcrawler colony in a single meal.
