Here's a breakdown:
* Average lifespan in the wild: 1-2 years
* Maximum lifespan in the wild: Up to 4 years
* Lifespan in captivity: 4-6 years
Their short lifespan is due to several factors, including:
* Predation: Opossums are prey for a variety of animals, including coyotes, foxes, owls, and hawks.
* Disease: They are susceptible to various diseases, including rabies and distemper.
* Starvation: Food availability can fluctuate, and opossums may struggle to find enough food during harsh winters.
* Injuries: They are often involved in car accidents or get injured while scavenging.
It's important to note that these are just averages. An individual opossum's lifespan can vary depending on its health, environment, and other factors.
