Wombat

The wombat is a medium sized marsupial that walks on all fours. These mammals live in grassy areas, and are known for burrowing. Wombats are considered to be the largest burrowing animal, and they can make burrows that extend for over 650 feet. When it comes to being safe from predators, the wombat will make smaller burrows that will extend only 7 feet. This is just enough for the wombat to have a place to hop into if they sense that there is danger in the area. Wombats have a number of characteristics that allow them to easily burrow under the ground such as sharp claws and compact bodies.
