This is a very odd way of protecting wombats from wild predators.

These marsupial animals living in Australia have a unique tactic for escaping from predators.

Sensing danger, the wombat rushes into its burrow and plugs the entrance with its buttock.

Surprisingly, the back of the wombat is so strong that it cannot be bitten or scratched.

This part of the wombat’s body is made up of thick skin and cartilage, making it virtually invulnerable.

This natural shield allows wombats to be safe even against such ferocious enemies as dingoes, foxes, dogs and even Tasmanian devils.

Moreover, a predator’s attempt to break through this barrier can be fatal.
