What is the primary defensive function of the Wombat's toughened rear hide?
Answer
It acts as a protective shield when the wombat wedges its rump against the tunnel roof
The posterior region of the wombat's body is reinforced with extremely thick skin, much of which is composed of dense cartilage. When a predator chases the wombat into its burrow, the wombat strategically retreats as far in as possible and jams its unyielding rump against the roof or wall of the tunnel. This firmly wedges the animal in place, effectively blocking the entrance and shielding the vulnerable head and body from attack. While folklore suggests they crush skulls, the primary confirmed function is using the rump as an impenetrable barrier.
