Some Centivorelights learned how to burrow efficiently through the ground, which they began using to get to Semavermis easier, though this lead to them specializing in them and their descendant, resulting in the Centivormole. They have lost their ability to photosynthesize, thus becoming pale and translucent, even losing their eyes, all because they now spend 95% of their life underground. They sense their environment entirely through smell and vibrations, having sorts of taste buds inside their mouth used for smelling, and having various hairs used for detecting vibrations and smells easier. They have evolved several teeth around the circumference of their two mouths, which make it easier to latch onto and swallow prey. Once prey has been detected, they begin digging away using their mandibles and feet, consuming a lot of rock and soil in the process, before finally getting to their target and attempting to grab and swallow them. They cannot easily tell species apart, so they sometimes commit cannibalism on smaller members of their species. Every once in a while, hundreds of mature Centivormoles emerge from the ground and attempt finding others of their species via pheromones, and will release clouds of spores when they meet to reproduce. They are now truly faunal, as cells are not easily changeable in some areas, nor can many survive very long outside the body.
