Opossum
Opossums have large mouths which contain a number of sharp jagged teeth.
In response to a threat however, an opossum is more likely to resort to a different tactic than biting, they pretend to be dead.
This is actually quite comical to see, the animal will open its mouth and roll out its tongue, looking for all the world like it is actually dead.
Since many of its predators will only eat live prey this tactic of "playing possum" is actually moderately successful.
Opossums will often live in hollow trees, bedding down during the day in dry leaves and debris and venturing out at night to hunt for food.
They will eat a wide variety of things, insects, eggs and corn being among their favorites.
They're also known by farmers for "stealing" chickens.
