Male vs Female Koalas: 5 Key Differences

Amazing animals, koalas are generally associated with Australia, along with the well-known kangaroo! These are solitary animals that prefer to remain in their particular habitat. The size of their house varies based on factors like their age and sex.

Speaking of, koala bears are different in a few ways from male to female. Continue reading to learn about the similarities and differences between these animals.

The main distinctions between a koala’s male and female forms are as follows:

The male and female koalas differ greatly in terms of weight. When they reach adulthood, female koalas can only weigh up to about 27 pounds, while male koalas can reach their maximum weight of 40 pounds.

Male koalas therefore weigh between 60 and 70 percent more than female koalas. The two sexes don’t really differ that much in terms of height. At two to three feet tall, the average koala is the same height regardless of gender.

Male vs. Female Koala: Physical Traits Male

The middle of the abdomens of mature male koalas has a pouch with an opening closer to the bottom of the stomach. A male koala’s genitalia are also visible on the outside.

Sweat glands are one of the simplest places to have sex with a koala. The middle of a man’s chest will have a deep, black crease.


The majority of female koalas also have a noticeable sweat gland on their abdomen, however it’s considerably duller and less noticeable. It has been noted that female koalas, like wombats, have a pouch that opens downward.

When a female koala gives birth, the opening of her pouch faces downward rather than upward.

Male vs. Female Koala: Reproduction

When they are three or four years old, males begin mating. As early as age two, females can begin to reproduce; for the next ten to fifteen years, they usually give birth once a year.

A koala doe gives birth to one joey during her 35-day gestation period. Although it is uncommon, female koalas can potentially give birth to twins. New babies are usually born in November through February.

Before they appear outdoors for the first time, the young spend the next six months within the pouch. Following that, the joey will spend the first year of its life riding on its mother’s back.

Male vs. Female Koala: Health

Koalas’ lifespan can be shortened by a number of diseases. These animals are specifically susceptible to one disease. In South East Queensland, a bacterial disease known as chlamydia affects a significant proportion of koalas.

Stress-related illnesses weaken the immune system, can cause blindness, and can damage the reproductive system, rendering a doe sterile. Infertility brought on by Chlamydia infections is one factor contributing to the current decline in koala populations.

Male vs. Female Koala: Temperament

Koalas may look cute and cuddly, but they are dangerous animals that can bite or injure you. Approaching them should never be done. Get in touch with a nearby wildlife agency if you come across an injured koala that needs help.


Even while they are really adorable to look at, goals may be very erratic. They absolutely detest being touched and dislike being near people. One exception exists. Petting a koala can be rewarding for a wildlife caretaker who is rearing an orphaned animal.

All the evidence that is available, however, indicates that koalas don’t appreciate it when strangers pet them. A koala can run up to 20 miles per hour on land. When they are frightened or afraid, they can leap up a tree seven feet high.

The majority of a koala’s time is spent resting. They tend to rest a lot due to the low nutritional value of their diet, but when they do move, they can move fast, readily, and forcefully.

Final Reflections

The male and female koalas differ in a few morphological and reproductive aspects. From a personality standpoint, they may share similarities. It is more crucial than ever to take care of these creatures because they are in risk from things like wildfires in their surroundings.
