The Australian Possum

Out of the 23 known possum species in Australia, there are two that you’ll most likely come across at night: the common brushtail possum (Trichosurus vulpecular), this latin name means “furry tailed little fox”, and the common ringtail possum (Pseudocheirus peregrinus), this latin name means “false hand pilgrim”. Possums are nocturnal and predominantly tree dwelling critters, making them arborial. They are also, like all possums, marsupials (the baby develops in an abdominal pouch outside of the womb).

First the Stats…

Scientific name: Trichosurus
Weight: Up to 7 lbs.
Length: Up to 20 inches (plus up to a 20 inch long tail)
Lifespan: Approximately 13 years

Now on to the Facts!

1.) A female possum is called a “Jill,” a male is called a “Jack”. Young possums are called “Joeys”. A group of possums is called a “passel”.

2.) These creatures are considered pests as they destroy crops and gardens as well as leave smelly feces and urine in their wake.

3.) Possums are primarily herbivores (eat plant matter), they favor eucalyptus and other leaves, buds, ferns, fruit, and flowers. Brushtail Possums are known to be tolerant of a variety of toxic plants and will eat plants that other critters find poisonous. Possums will also eat insects, grubs, moths, snails, bird eggs, and baby birds.

4.) These possums communicate through a series of clicks, hisses, coughs, grunts, chattering, and screeching.

5.) Australian possums are territorial animals and will typically urinate and rub oil from glands on their chest, chin, and anus to mark their territory.

But wait, there’s more on the Australian possum!

6.) Even though they are territorial, they are not usually aggressive. If confronted by another possum, they will stand still and make their ears stand up to signal that this is their territory. If trapped though possums can and will defend themselves by spraying urine, biting, scratching, and shrieking.

7.) Possums can sometimes carry a variety of ticks, mites, and other parasites; including bacterial infections (some of which are zoonotic [can be transmitted humans]). Possum feces may also carry the buruli bacteria, which can cause large skin ulcerations in humans.

Did you know…?
The Common Ringtail is the only species of possum known where the male assists in caring for the young.

8.) Australian possums have a prehensile tail which allows them to grasp branches, when navigating through trees, like having another hand. They also use their tails for carrying nesting materials too, such as bunches of grass and twigs by wrapping their tails around the item in question.

Critter Man

With over 40 years of critter experience to my credit and hundreds of zoology teaching hours to people around the world, I have amassed not only a continuing thirst for critter knowledge but a desire to teach others all I can about the majesty and wonder of our natural world. Critter Science is a culmination of such knowledge.I have hands on as well as book acquired intel on all kinds of critters. Whether they're on land, sea, or air.I will never say that I know everything about all animals. That's impossible, even for a savant. But, that being said, ask me any animal question and I'll answer it. If I don't know the answer, I'll get an answer for you!Let it be said that I have been oft times accused of loving animals more than I love people. I can neither confirm nor deny this.
