The backyard marsupial that fakes its own death automatically
This animal fakes its own death so convincingly its body does it automatically.
Which one is REALLY true about the Opossum?
The short version
The opossum is North America's only marsupial. When truly terrified it drops into an involuntary coma-like state, drooling and releasing a rotting smell to seem like a corpse — lasting minutes to hours. Its low body temperature makes rabies rare in it, it resists many snake venoms, and it has 50 teeth, the most of any North American land mammal.
Why it's so weird
- ✓The Opossum is North America's only marsupial.
- ✓The Opossum shuts its body down into an involuntary, coma-like state when it is truly terrified.
- ✓The Opossum drools and releases a foul, rotting smell to fool into thinking it is a days-old corpse.
- ✓The Opossum almost never carries rabies, because its low body temperature makes the virus hard to survive inside it.
- ✓The Opossum has fifty teeth, more than any other land mammal in North America, and resists many snake venoms.

The full story
This animal is so good at playing dead that it does not even choose to do it. Meet the opossum, North America's only marsupial, and one of the most misunderstood creatures around. When it is truly terrified, its body shuts down into an involuntary, coma-like state. It flops over, drools, and releases a foul, rotting smell, fooling predators into thinking it is a days-old corpse. This trance can last from a few minutes to several hours. But opossums are also secret superheroes of the backyard. Their unusually low body temperature makes it very hard for rabies to survive inside them, so they almost never carry it. They are even resistant to many different snake venoms. And with fifty teeth, they have more than any other land mammal in North America. Ugly, weird, and surprisingly helpful to have around.

Playing dead isn't a clever choice the opossum makes — it's an automatic reflex called tonic immobility that its own nervous system triggers when a predator terrifies it. The shock makes its body flop limp and stiff, and its heart and breathing slow way down, while glands near its tail ooze a foul, rotting-meat smell. Many hunters avoid prey that already looks and smells dead, because spoiled meat can make them sick, so the predator loses interest and leaves. The opossum can't switch this off on purpose; it only 'reboots' on its own, minutes to a few hours later, once the danger has passed.
