Snapjaw Sandcrock

The snapjaw sandcrock split from its ancestor and become a highly successful ambush predator. While hunting the sandcrock buries itself most of the way into the sand an waits, some times for weeks, for unwary prey to come near. Once it acquires a target it springs from cover, stabbing and slicing with its shoulder spikes and biting and rending with its powerful jaw. Their legs are well adapted to this springing strategy, the hind limb ankle for example can pivot nearly 180 degrees, keeping the foot still while the rest of the body is rocketed forward. They are no longer social and have lost the communication flap of their relatives. Individuals meet rarely and only for mating. Fertilization is internal and larva are born limbless but with well developed lungs. Due to their smaller size, camouflage, and slow metabolism they have managed to put pressure on the Shantak.
