Splitting from its ancestor, the noomroach moves to the beach. It has lost its amphibious ability and it can't spit fluid, since there are no flytikers on the beach. To breath, it uses invertebrate trachea. Now it eats rustballs instead, but it can still scavenge. It has developed a shovel like formation on its back, with which it makes holes. During the day, it hides in these tiny caves, to escape from predators. At night it becomes active and leaves its hole.
