2. Kangaroos can leap 25 feet in one jump

Red kangaroos (Macropus rufus) are the world’s largest marsupials. They also have powerful hind legs and large feet that help them leap an astounding 25 feet in a single bound4.

This incredible leaping ability they are famous for enables the red kangaroo to navigate their expansive environment easily while also evading their few natural predators, such as wild dogs called dingoes. Furthermore, these kangaroos hopping around can clear obstacles like fences or walkways.

While hopping, they can also reach speeds of up to 35-40 mph, which proves particularly useful when searching for food and water over long distances in the arid outback. 

Interestingly, red kangaroos expend less energy as they hop faster, making them exceptionally efficient travelers. This efficiency stems from their mighty leg muscles and spring-like tendons that store and release energy with each hop, propelling them forward and maintaining momentum.

The red kangaroo's hopping prowess also plays a vital role in regulating its body temperature. Bouncing around, they expel heat with each jump, allowing them to stay cool in the scorching Australian climate. They have a long tail, providing balance and stability, even when they hop backward.

1. Kangaroos live everywhere in Australia

The four species of kangaroo belong to the Macropodidae family and the order Diprotodontia and live in various habitats across the world’s smallest continent. Take the eastern grey kangaroo (Macropus giganteus), which thrives in the grasslands and forests of eastern Australia.

Contrast this with its western counterpart, the western grey kangaroo, which prefers the continent's southern regions. In the north, you'll find the antilopine kangaroos, known for their striking, antelope-like appearance.

Smaller relatives, such as wallabies, tree kangaroos, and pademelons, add to the richness of the kangaroo family. Wallabies, for instance, demonstrate their adaptability by inhabiting forests, grasslands, and swamps. On the other hand, tree kangaroos have evolved to live in rainforests, developing unique adaptations for climbing trees.

Colors and sizes among most kangaroos vary greatly. With its namesake reddish hue, the red kangaroo stands at an impressive 1.8 meters tall. Meanwhile, the parma wallaby, one of the smallest species, reaches a modest height of around 1 meter.

3. Female kangaroos have three sexual organs

Female kangaroos boast a great three-vagina arrangement, which includes two lateral vaginas for sperm transport and a central one for giving birth. This intricate design lets them mate with several partners and even carry embryos from different males.

Meanwhile, male kangaroos have bifurcated penises, splitting into two prongs. These prongs perfectly match the female's lateral vaginas, ensuring effective sperm transfer during mating.

Besides their unique anatomy, kangaroos display impressive reproductive flexibility. Female kangaroos can engage in embryonic diapause6, which allows them to pause their embryos' development during environmental stress or resource scarcity.

4. They have pouches for their offspring

Found in female kangaroos, the marsupial pouch serves as a nurturing sanctuary for baby kangaroos called joeys. Newborn joeys are remarkably underdeveloped, roughly the size of a lima bean, and must immediately crawl into the pouch to continue their growth5. The young kangaroo remains safely ensconced within this warm, comfortable environment for up to eight months.

Inside the mother’s pouch, specialized teats provide milk for the joey’s nourishment. As the joeys grow, the milk's composition adapts to meet their changing nutritional needs. The pouch consists of solid muscles that contract to secure the joeys during the mother's swift, high-speed movements.

In the face of danger, a mother kangaroo can expel her offspring from the pouch to reduce her weight and enhance her mobility, returning to retrieving the joey once safety is assured.

As baby kangaroos approach independence, they venture beyond the pouch, exploring their surroundings while still seeking comfort and nourishment from their mother. Despite outgrowing the pouch, the young kangaroo occasionally returns to nurse or find solace.

5. Kangaroos use their tails as a “fifth leg”

Unlike most animals, kangaroos cannot move their hind legs independently while walking. This physical trait compels them to rely on their solid and flexible tails to support their weight as they move both legs simultaneously. As they graze leisurely or travel slower, the tail is a vital anchor, providing stability and balance.

The kangaroo's tail serves multiple purposes. One of its most important roles is enabling the animal's distinctive gait, known as "crawl walking." During “crawl walking,” the tail touches the ground first, followed by its hind legs. As the kangaroo's pace increases, the tail shifts to a counterbalancing role, enabling the marsupial to execute swift, precise hops across the landscape. 

Beyond mobility, kangaroos' tails offer an array of versatile functions. For instance, these animals depend on their tails to maintain an upright posture, using them as stabilizers while standing. Furthermore, kangaroos employ their tails to generate momentum for forceful kicks, which can serve as self-defense or during confrontations with other kangaroos.

6. They are strict vegetarians

From the western grey kangaroo to the antilopine kangaroo, these marsupials are strict herbivores, thriving on a plant-based diet made up mostly of grass. In Australia's vast landscapes, these marsupials happily graze on native grass species such as Mitchell grass and kangaroo grass. 

Their specialized digestive system features four distinct chambers, enabling them to break down and extract nutrients from plants efficiently, even when food is scarce.

You might be surprised to learn that kangaroos share some similarities with cows regarding feeding habits. Both animals are grazers that rely on grass as their primary food source. 

However, kangaroos generate significantly less methane while breaking down cellulose found in plant cell walls. This is thanks to unique bacteria within their stomach chambers that assist in fermentation and reduce methane emissions as a byproduct2. As a result, kangaroos are seen as more environmentally friendly grazers than other herbivores like cows.

Kangaroos’ feeding habits also reveal their remarkable adaptation to Australia's harsh climate. They prefer grazing during cooler parts of the day, such as early mornings and late afternoons, which helps them conserve energy and stay hydrated. Moreover, kangaroos have developed strong, flexible jaws and continuously growing molars, allowing them to grind and consume various plant materials effectively. 

7. Kangaroos perform unique mating behaviors

In kangaroo courtship and mating rituals, male kangaroos, or boomers, employ various tactics to demonstrate their prowess and attract a potential mate.

One of the most compelling aspects of their courtship behavior is their demonstration of strength and agility, which indicates to the female kangaroo, a flyer, that the male possesses robust genes suitable for producing strong offspring.

During mating season, boomers engage in intense physical contests with each other, competing for the attention and favor of a nearby flyer3. These battles involve wrestling maneuvers, gripping each other with their forearms, and delivering powerful kicks using their hind legs. 

As the males vie for dominance, the flyers observe from a safe distance, carefully assessing which boomer appears to be the fittest and most capable. The winner of these contests secures the female's interest, thus increasing his chances of successfully passing on his genes.

In addition to these dramatic physical displays, the male kangaroo employs subtler courtship behaviors. For example, a boomer might sniff a flyer's urine to determine if she is in heat and ready to mate.

Additionally, the boomer may produce soft clucking sounds or gently paw the ground as part of his courtship display. Though less eye-catching than physical contests, these quieter behaviors play a crucial role in the intricate dance of kangaroo courtship and mating rituals1.

8. They know how to box

Running around in small groups called troops, male kangaroos pound each other to play, communicate with other kangaroos, and establish dominance in social groups. These physical interactions are vital to kangaroo society and contribute to community harmony.

While boxing, male kangaroos stand upright, striking opponents with their front limbs while relying on their sturdy tails for balance and support. These encounters can last from a brief few seconds to several intense minutes, depending on the intensity and purpose. Younger males often practice boxing to sharpen their skills for future dominance challenges. 

In contrast, more experienced kangaroos may use these matches to communicate their group position or compete for mating rights.

Interestingly, kangaroo boxing is not exclusive to males. Though less common, experts have observed female kangaroos sport their physical strength in a boxing match. However, they typically don't compete for mating rights or dominance like males.

9. They can survive droughts

Remarkably, they possess an innate ability to adapt to drought conditions. A striking adaptation is their minimal water requirements; they consume as little as one-fifth the amount needed by a similar-sized animal, like a sheep.

To conserve water, kangaroos develop specialized kidneys that help them produce concentrated urine, effectively reducing water loss. They can also reabsorb water from their feces in the colon, minimizing waste even further. Likewise, kangaroos can go without drinking water for several months during extreme scarcity, relying solely on the moisture from their food sources.

Besides their physiological adaptations, kangaroos exhibit drought-resilient behaviors and food consumption habits. They are more active during cooler parts of the day, such as dawn and dusk, minimizing heat stress and water loss.

They feed on drought-resistant plants with high water content, like succulents, which provide the necessary hydration. Their muscular structure allows them to travel long distances for water and food.

10. Kangaroos’ teeth grow forever

Kangaroos have a distinct dental structure designed for their herbivorous diet of fibrous plants like grasses and leaves. For instance, their teeth can grow continuously, which is vital for their survival and equips them to handle the relentless wear and tear from grinding down tough plant material.

Kangaroo teeth contain a dense substance called cementum, giving them the strength and durability needed to break down fibrous materials effectively.

The kangaroo's dental structure consists of six incisors in the upper jaw and two in the lower jaw. Their molars are specifically designed for grinding. As they chew, kangaroos move their teeth in a circular grinding motion, skillfully breaking down food before swallowing.

Over time, "molar progression" occurs, where the worn molars at the front of the jaw are pushed out and replaced by new molars emerging at the back.

11. They are left-handed

Did you know kangaroos, like humans, have a preferred hand? A 2015 study by Yegor Malashichev from Saint Petersburg State University in Russia discovered this unusual preference. By observing over 100 kangaroos and wallabies in their natural habitats across Australia and Tasmania, researchers found that 95% of the marsupials they observed consistently prefer using their left hand for tasks like grooming and eating. 

This finding is even more fascinating because left-handedness was more evident in bipedal species, such as the red kangaroo, eastern gray kangaroo, and red-necked wallaby. Researchers believe their upright posture might have allowed for the development of better motor skills and coordination. 

Moreover, this groundbreaking study challenges the long-held belief that handedness is a trait unique to primates.

12. They drown their enemies, sometimes

Over the centuries, kangaroos have developed their own unique self-defense method to help protect them from predators like dingoes, eagles, and foxes. These marsupials use their swimming skills to turn the tables on predators looking to feast on kangaroo meat.

When pursued by a threat, the kangaroo heads for the water and waits for its enemy to follow. The kangaroo springs into action once the attacker is submerged, using its powerful hind legs as a formidable weapon.

Holding the predator underwater, the kangaroo drowns its enemy, transforming an escape route into a lethal trap. Curiously, this drowning technique has been observed in both wild kangaroos and those in captivity.

13. They are threatened by habitat loss and climate change

Some kangaroos, like the eastern grey kangaroo, have become threatened species due to a vanishing habitat and climate change. Various conservation efforts have been implemented to address the challenges these kangaroos face.

For instance, the Australian government has implemented the National Recovery Plan for Eastern Grey Kangaroos, which focuses on supporting healthy populations by restoring and protecting essential habitats. 

Collaborative initiatives like the Land for Wildlife program encourage landowners to conserve and enhance native vegetation on their properties, creating crucial refuges and sanctuaries across Australia. Additionally, wildlife corridors connect fragmented habitats, promoting genetic diversity and allowing kangaroos to move freely between areas.

Monitoring and managing threats is another vital aspect of kangaroo conservation. Regulated culling programs help control overpopulation, reducing human-kangaroo conflicts and easing resource strain. 

Researchers continuously monitor kangaroo populations to inform adaptive management strategies and assess climate change impacts on habitats. Public education campaigns work to dispel misconceptions about kangaroos and raise awareness about their conservation needs. As do our collection of kangaroo quotes - feel free to give them a share!
