Behavior and Threat Profile
The opossum is North America's only marsupial and one of its most effectively adapted scavengers. It eats almost anything. It survives almost everything. It is immune to most snake venom. It is not fast, it is not dangerous, and it is not going anywhere.
The "playing dead" behaviour, thanatosis, is involuntary. The opossum does not decide to play dead. It enters an involuntary catatonic state when overwhelmed by threat. It drools, it releases a foul odour, it goes completely limp. Most predators lose interest.
On Leonida's rural roads it is a persistent night hazard. Slow movement, poor road awareness, and high nocturnal activity mean rural route driving at speed will encounter opossums regularly. They do not move.
