An analysis of mammalian bite force, corrected for body size, shows that the Tasmanian Devil has the strongest bite of any living mammal.

The Tasmanian Devil stores body fat in its tail and an unhealthy devil often has a thin tail.

Tasmanian devils give birth to 20-30 young, each weighing approximately 0.18-0.24 grams. When the young are born, they move from the vagina to the pouch. Once inside the pouch, they each remain attached to a nipple for the next 100 days. Despite the large litter at birth, the female has only four nipples, so that no more than four young can survive birth. Those who do not procure a nipple are typically eaten by the mother.

Wombats have an extraordinarily slow metabolism, taking around 14 days to complete digestion, and generally move slowly. When required, however, they can reach up to 40 km/h and maintain that speed for up to 90 seconds. This is particularly remarkable because unlike other fast animals wombats walk and run on full feet.

When attacked, Wombats can summon immense reserves of strength one defense of a wombat against a predator (such as a Dingo) underground is to crush it against the roof of the tunnel until it stops breathing. Its primary defence is its toughened rear hide with most of the posterior made of cartilage which, combined with its lack of a meaningful tail, presents a difficult-to-bite target to any enemy who follows the wombat into its tunnel.
