Kangaroos are known for their pouches, where their little ones develop. However, only female kangaroos have it, and males don't because they don't nurse their newborns.
Do Male Kangaroos Have Pouches
A male kangaroo is called a buck, boomer, or jack, while a female is called a doe, flyer, or jill. Baby kangaroos, on the other hand, are known as joeys.
Boomers don't have pouches because they do not do child-rearing. Additionally, they do not produce milk to nurse their little ones.
The pouches are designed to feed premature baby kangaroos. It expands in size as the joey develops inside, and the nutrients change to adapt to the growing resident's age. Aside from supplying the joey's nutritional needs for their nourishment, the pouch also releases antimicrobial substances to protect or minimize the risk of infection.
Kangaroos' genitalia are also unusual. Female kangaroos have three vaginas and two uteruses. Males have long penis behind their scrotum, which retracts when they hop or engage in coitus.
It means that while hopping or engaging in sexual activity, its balls are pulled against its body rather than dangling under it. The animal's testicles must be kept inside the dangling scrotum at 2-5 degrees below the animal's core body temperature. Another defense mechanism against Australia's severe environment is the boomers' body's ability to stop producing sperm during a severe drought to save energy.

Everything to Know About Boomers
Male kangaroos are popular for their muscular bodies. They have broad and firm chests and bulging biceps.
They are genetically predisposed to be muscular. Pure muscle accounts for 50% of their total weight. As a result, they are naturally buffed animals. These marsupials have various things working in their favor that make them highly muscular.
Male kangaroos fight for supremacy. Their fights are called "boxing matches," just like an actual boxing match; they make for the best workout.
Boomers engage in physical combat, pushing and punching one other like boxers. They also strike with their front claws, which are razor-sharp. Additionally, kangaroos have a special "kickbox" move in which they balance on their tail while kicking their opponent with their back legs.
These actions show that they are utilizing all their muscles and, in a sense, exercising while fighting. After all, they acquire more muscle mass the more enthusiastic they are. Furthermore, the victor of war is typically one of the most powerful men. Being the strongest and most toned therefore pays dividends!
Typically, they clash to establish dominance and mate with females. If the dominant male prevails in all battles, he will likely be the only kangaroo in the group to mate with the females. Research has also found that female kangaroos are drawn to the strongest males, which is why they are so attractive. In other words, all that exercise is paying off!
Also, their muscular build could be due to genetics. The red kangaroo is the largest species in the genus and the largest marsupial on the entire planet. These animals have two forelimbs, two hind legs, and a muscular tail and may move in several ways.
Half of the red kangaroo's body weight is made up of muscle. Additionally, they have more mitochondria. Animals that exercise more frequently have more muscular mass than species that do not.
