Difference Between Opossums and Possums (With Table)

Earth is filled with lots of unique species of living organisms. Every continent has hundreds of unique species of animals. These species are found in certain places due to the required environment. They choose their habitats depending on many factors. Similarly, opossums and possums are two such species that live far away from each other on different continents.

The opossums are known to carry illnesses like tularemia, leptospirosis, spotted fever, coccidiosis, etc.

How astonishing it is that some species who look alike live so far from each other. How did they get there, and what is the reason they live like this? Scientific researches have answers to all these questions.

The environment of a place is a significant factor that influences the kind of animals living there. The atmosphere is so essential that birds and animals migrate from place to place in specific seasons. Opossums and possums are also two such examples.

They resemble each other. On top of that, they belong to the same family. But scientifically, possums and opossums are two different kinds of animals.
