The beach scorpion sauceback replaced its ancestor on the beaches and grew in size. Its tusks have become very sensitive to vibrations and have gotten much longer than its ancestors, they are now used by being poked into the sand to feel for things walking on or digging in the beach. The tail has become very muscular and the dagger on the end has growths on it to dig up and to flip prey for easier killing. The infra-red sensing pad on its face has grown to give it better 'vision'. They live solitary lives and their larvae dig in the sand eating shellworms and centiworms.
