Kangaroo Description What Does A Kangaroo Look Like?

Kangaroos are large, herbivorous marsupials known for their unique mode of movement—hopping on powerful hind legs. They have a distinctive deer-like face with a long, narrow snout and large, swivelling ears. Their eyes, positioned high on their heads, provide an incredible 324° field of view, allowing them to detect potential threats with ease. With exceptional hearing, kangaroos can pick up sounds from up to 2 kilometres away.

Male kangaroos are larger than females, and female kangaroos have a pouch in which they carry their young. Kangaroos cannot hop at low speeds. So, they walk on five legs! Yes, that's right.

Kangaroo’s Powerful Hind Legs Incredible Hopping

The kangaroos' powerful hind legs and narrow feet are built for speed and endurance.
They can:
- Hop at high speeds and leap up to three times their height.
- Store and release energy with each bounce for efficient movement.
- Make sharp 180-degree turns in a single hop.
- Move both legs together when hopping but also use them independently when necessary.
- However, kangaroos can’t hop backward easily due to muscular structure of its tail.

The Kangaroo's Multi-Purpose Tail The Kangaroo's 3rd Leg

The kangaroo's large and thick tail counterbalances its body, providing stability while hopping and acting as a tripod when standing to prevent it from toppling over. It can bear the full weight of their body when fighting and stores excess fat, providing energy during times of scarcity.

Besides using their front limbs and rear legs, they also use their tails as a leg. This unique way of walking is called pentapedaling.

Contrary to popular belief, kangaroos do not use their tails as rudders while hopping!

Kangaroo's Remarkable Forelimbs Unique Cooling Method

Kangaroos have small but strong forelimbs with five clawed fingers, which they use for grasping branches, grooming, and even fighting. Interestingly, kangaroos are predominantly left-handed, favouring their left hand for feeding and grooming. (Fun fact: Elephants are also known to be left- or right-handed!)

To cool down in the harsh Australian heat, kangaroos lick their forearms, coating them in saliva. As the saliva evaporates, it helps lower their body temperature—a built-in air-conditioning system!

Kangaroos also use a unique crawl-walking technique called pentapedaling when moving at slow speeds. They lean on their front limbs, lift themselves with their powerful tail, and then bring their hind legs forward.

How Kangaroos Communicate Vocalisations, Gestures, Foot Thumping

Despite having tiny, almost non-existent vocal cords, kangaroos use a variety of sounds and physical gestures to communicate:
- Mothers click softly to bond with their babies.
- Alarmed kangaroos hiss and growl.
- Aggressive kangaroos emit a sharp "ha" sound.
- Males chuckle during courtship.
- All kangaroos thump their feet to warn others of danger.

Kangaroo's Pouch A Nursery on the Move

Female kangaroos have a built-in nursery—a pouch on the front of their bodies where they carry and nurture their young. Baby kangaroos, called joeys, are born extremely underdeveloped and must crawl into the pouch immediately after birth to survive. Inside, they attach to a milk nipple and continue developing for over four months before venturing outside. Male kangaroos do not have pouches.

Kangaroo Habitat Where Do Live?

Kangaroos inhabit the temperate to hot climates of Australia, such as open plains, grasslands, deserts, and scrublands. The red kangaroo resides mainly in Australia's arid and semi-arid interior. The eastern grey kangaroo typically inhabits the moist scrublands of the east, south, and south-west regions. The western grey kangaroo is found in grasslands and open woodlands in southern Australia. Conversely, the antilopine kangaroo prefers tropical forests with grassy ground cover in the northern regions.

Kangaroos are nocturnal animals and are most active around dawn and dusk. They move around in small social groups called 'mobs' or 'troops'.

Kangaroo Diet What Do Kangaroos Eat?

Kangaroos are herbivores and feed mainly on grasses, leaves, ferns, flowers, fruits, and occasionally moss. They obtain most of their required moisture from their diet, allowing them to survive for months without drinking water.

Kangaroos have a chambered stomach, similar to horses, that includes a U-shaped fore-stomach that helps them digest fibrous plant material that is too tough for other animals to digest. Kangaroos regurgitate their food, chew it again and swallow it—to further break down fibres and enhance digestion.

Kangaroos prefer feeding at night but also graze early in the morning and late evening when the temperature is cooler. During the hotter periods of the day, they usually rest in the shade. Kangaroos possess an exceptional ability to sense changes in weather and can detect rainfall from as far as 20 kilometres (12.5 miles) away  and instinctively move toward areas expecting new plant growth to emerge after the rain.

Kangaroos have four sets of front incisor teeth for shearing grass or leaves and four sets of large molars at the back of their mouths for grinding their food. Four sets of replacement teeth grow during the animal's lifetime, after which lost teeth are not replaced. If the animal hasn't died of old age by then, it will eventually die of starvation because it has no teeth left.

Kangaroo Reproduction Kangaroo Babies

Kangaroos, being marsupials, give to very undeveloped young. The newborn kangaroo baby is no larger than a jelly bean (2 cm or 0.79in) and weighs less than one gram. Despite its tiny size, after birth, the joey instinctively uses its underdeveloped arms to crawl up its mother’s fur and into her pouch.

Once inside its mother's pouch, the joey attaches itself to a nipple in its mother's pouch and remains hidden for about six months relying entirely on its mother for nourishment and protection. It will then start popping its head out of the pouch curiously observing the world around it. About two weeks later, it will venture out of the pouch and hop about staying close to its mother for reassurance. By eight months, the joey stops using the pouch altogether but continues to live with its mother for up to two years before becoming fully independent.

A kangaroo reaches sexual maturity at around 16 months for females and 24 months for males. They do not have a fixed breeding season, though they tend to reproduce more frequently when food is abundant. Kangaroos live for 22-25 years.

Do Kangaroos Throw Their Babies Away? Yes and No

No, kangaroos do not throw their babies. They cannot physically do so with their arms and hands. However, a female kangaroo may eject her baby from her pouch when attacked by a predator. This is to draw the approaching predator to her abandoned baby allowing the female to escape. From a biological perspective, this approach is sound. By sacrificing her baby, the mother saves herself, rather than both mother and baby falling prey to the predator. She can then go on to produce more babies.

Kangaroo Fighting Do Kangaroos Box?

Kangaroos are not aggressive animals and rarely fight. Instead, fights usually break out over mating rights and are more ritualistic than aggressive. Contrary to popular folklore, kangaroos do not punch or box the way humans do. Instead, male kangaroos fight by kicking their opponent with their powerful hind legs and hitting and clawing with their front paws, which have sharp claws. Very rarely do kangaroos hurt each other during these fights.

Kangaroo Swimming Can Kangaroos Swim?

Kangaroos are surprisingly adept swimmers! Despite the arid habitats they usually live in, kangaroos are often seen swimming in oceans or wading in rivers and watering holes. Their swimming skills are achieved by "dog-paddling" with all four limbs. Kangaroos often flee into watering holes and rivers when threatened.

Kangaroo Drowning Dog

Kangaroos are typically not aggressive, but pursued by especially by dogs or dingos they can defend themselves in unexpected ways. If near a body of water, a kangaroo may instinctively flee into the water, using it as a defensive advantage. If the dog follows, the kangaroo may turn and stand its ground, grabs its assailant with its powerful arms and hold it underwater in and attempt to drown it. his defensive behaviour is rare, but has been observed when kangaroos feel cornered and have no other means of escape. There have been no reports of kangaroos drowning people because a person would be pretty foolish to follow a kangaroo into water.

Kangaroo Predators and Threats What Kills Kangaroos?

Kangaroos are typically non-aggressive, but if pursued, especially by dogs, foxes or dingoes they can defend themselves in unexpected ways. If near a body of water, a kangaroo may instinctively flee into the water, using it as a defensive advantage. If the dog follows, the kangaroo may turn and stand its ground, grabs its assailant with its powerful arms and hold it underwater in and attempt to drown it. This defensive behaviour is very rare, but has been observed when kangaroos feel cornered and have no other means of escape. There have been no reports of kangaroos drowning people because a person would be pretty foolish to follow a kangaroo into water.

Kangaroos are generally safe from predators due to their size speed and powerful kicks. However, young kangaroos can be vulnerable to threats from eagles, dingoes, foxes and certain dog breeds. If pursued by a predator, kangaroos may attempt flight into waterways and may use their clawed forepaws to grab and drown the assailant. Kangaroos rarely succumb to illnesses in their natural habitats. Droughts, motor vehicle accidents, hunting and intentional culling by the government have caused the highest mortality rates for this species.

How Many Kangaroos in Australia? Are Kangaroos Endangered?

With an estimated population of 50-60 million, kangaroos are not considered endangered. The ICUN lists them as an animal of "least concern". However, because of their large numbers and the severe crop damage they cause, the government allows the culling and harvesting of 1-2 million animals each year.

Extinct Kangaroos

The procoptodon was a giant short-faced kangaroo that stood about 2m tall and weighed as much as 240kg. It was too heavy to hope and probably walked on its hind legs. It lived in semi-arid areas of South Australia and New South Wales and had a diet of leaves from trees and shrubs. The procoptodons became extinct between 45,000 and 18,000 years ago. They seem to have become extinct after the arrival of humans. Their extinction may have been caused by human hunting, or by human fire-based deforestation in Australia.
