Flailing Limbless

The flailing limbless split from its ancestor and is in fact even preyed by it at times. As its ancestor the sanddigging serpentsaur’s diet became much more limited and consisted only of the fuzzy scuttlecrabs' adaptations for specification became common and naturally encouraged. Therefore generations of slightly smaller individuals roamed the beach. Still the main mutation that created the flailing limbless was originated from something completely different. While most of the adult sanddigging serpentsaurs gathered great amounts of fat in their bodies and only shed it near the mating season, in order to get the mates first a new mutation evolved decreasing the amount of fat they gathered in their bodies. As they further evolved to become lighter and more mobile they became adapted to a new niche of predators, forsaking their ambushing ways for a more aggressive hunt of the fuzzy scuttlecrabs. Their movement improved as well as they started hopping by waving their tails and bodies. They also evolved two backside spikes for better movement and gaining momentum when jumping. Finally they evolved a weapon most suiting against their main prey, a tail flail. Their whole preying strategy became based on it as they caught their prey with the mouth, turned over to the side and then smash it down with a few hits using the tail.
