Opossums Feign Death

The opossum cannot move very quickly. So what should it do if an enemy approached? It rolls up, sticks out its tongue and stays lying down with open eyes. It also emits a foul smell. The opossum can get through this deception for up to six hours.

Weird Walk

Opossums do not walk like dogs, cats, or horses. These put their paws or hooves offset (apart from the "pass" in horses, a special gait). Opossums move their limbs on one side of the body simultaneously – left front and back paw, then right front and back paw.

No Rabies

Opossums cannot be infected with rabies. They have an extremely effective immune system that can deal with many viruses and bacteria. They also have a rather low body temperature, which makes it difficult for bacteria to multiply.

Grannies and Grandpas

Opossums have been roaming the earth for 70-80 million years, making them one of the oldest living "fossils".

And the winner is ...

Opossums are the biggest possums and can reach the size of domestic cats.

Clean Rat

The opossum is very tidy. Before a female opossum gives birth, it thoroughly cleans its pouch for the young.


Generally, opossums are loners. The animals only come together during the mating season. With just about 12 - 14 days, they have the shortest gestation period of all mammals. After birth, the babies are just about 0.39-0.78 inch (1-2 cm) long and weigh between 0.004 and 0.007 oz (0.13 and 0.20 g). After 2-3 months, the young animals leave the pouch for the first time and climb onto their mother’s back.
