Opossums are quite often referred as ‘the living fossil’, as they have been residing on earth since the dinosaur age. They have been known to inhabit the earth since the past 70-80 million years, making them one of the world’s oldest surviving mammals. Existing in various sizes and weights, opossums have white face, hairy grey body, naked ears and a scaly tail. Though they do look like rats, they are not at all related with them. Rather, they can be similar to cats, in a way that they are extremely clean and groom themselves often. Often called possums, they are extremely versatile animals. They are efficient swimmers, climbers and also extremely adaptable. They eat a variety of foods and reproduce rapidly. Opossums are also solitary and nocturnal animals.
