Without legs, how does a snake dig a burrow?

Snake is the common name for a group of carnivorous reptiles, each with long round legs and bodies (cylindrical), belonging to the suborder Serpentes. Like other scaly reptiles, snakes are ectothermic, amniotic, vertebrates with stacked layers of scales that cover their bodies. Most snakes are non-venomous, and those that are venomous use it mainly to kill or subdue prey rather than for defense. Some species have venom powerful enough to cause painful or fatal injuries to humans. Non-venomous snakes either swallow their prey alive or kill it by wrapping and twisting.

According to the Snake Removal site, although snakes are usually burrowers, most of those burrows are not made by them. Usually, they will find burrows and holes - which are "homes" for other animals (frogs, turtles, mice) to live. If the real "owner" of the cave is still inside, the snakes will attack and even eat meat to take over the cave. If the cave is abandoned, the snake automatically becomes the new "owner".

To answer the question: Can snakes burrow underground? The Snake Removal page gives the answer no. Snakes cannot burrow, but they can sometimes burrow into soft, loose soil or sand. However, this is seen as an act of burying oneself instead of burrowing.
