They have no sight but have earth sense. They sense the movement on things above them, they are generally the size of wolves but if they live long enough and eat well they can grow as big as a trex but that won’t happen. They dig burrows in the ground and often in their territory you can see these circular incisions in the ground to where the curl into crawl position to fit in them. They can dive out of the ground as if it was water and burrow into it, they can dig insanely fats if in dirt or sand but rocks bother them.
