9 Facts About Opossums

9 Facts About Opossums

Here are more surprising facts about opossums:

1. Opossums Are Incredibly Agile

You may think that opossums are clumsy when you see them playing. The real score is that they’re excellent tree climbers because of their sharp claws and opposable thumbs.

With the prehensile tail, it’s effortless for them to hang on branches. It’s an essential skill as they live in tree hollows.

2. Opossums Make Strange Noise

It’s a rare chance to hear some noises from opossums. The young ones make a ‘choo-choo’ sound when calling their mothers which will respond with a clicking sound.

During mating season, it’s the male opossum that makes the clicking sound. When these creatures feel threatened, they may growl or hiss.

3. They Are Nature’s Cleaners

Opossums are omnivores, so they eat both animals and plants. Because of this, they are nature’s cleaners as their diet includes reptiles, birds, amphibians, small mammals, insects, eggs, and fruits.

They can even devour dead animals and venomous snakes without leaving a trace. Moreover, they can clean your garden by eating slugs, snails, and rotten fruits.

4. They Piggyback Their Young

Joeys or baby opossums come out from their mother’s womb hairless and blind. They’re big as a coin, and they continue to grow in their mother’s pouch.

There are only 13 teats on a mother that can give birth to up to 20 babies. So only those that can latch on the teats can luckily grow into adults.

In two-month times, the joeys can go out from their mother’s pouch and return by themselves. They’re old enough to have a piggyback in the said period.

5. They Help Curb Diseases

Opossums as marsupials are mammals. But they don’t cause Lyme disease. Instead, they curb it as they can consume thousands of ticks that bring the disease. They eat almost 90% of ticks that stick to their bodies. According to the University of Florida, opossums can consume a total of 5,000 ticks in one season.

6. They Have Impressive Tails

They have an impressive, prehensile tail that works as an arm. This part of their bodies is used in different tasks. It comes in handy when they need to take some leaves and grass to their nests.

Their tails give stability when they grip on the tree. Even the babies know how to hang on the branches through their tails.

7. The Play Dead

They play dead when predators are around. Due to intense fear, opossums fall on the ground with the tongue out and blank eyes. It’s a very convincing defense mechanism, and some predators will leave and look for another target.

However, the downside is that they don’t have control over their bodies when they play dead. It’s an involuntary response when they’re triggered by stress. Therefore, they can’t go back to the normal state as they wish.

8. They Can Stink

This part is connected with their ability to play dead. While it appears to be dead to its predator, it discharges a smelly substance from its anus. It’s the reason why predators move away and look for different prey.

9. They’re Immune to Rabies and Venom

As a marsupial, an opossum has a lower-body temperature, which doesn’t give room for rabies or virus to survive. The reason why it eats snakes without any adverse effect is the peptide found in its body.
