An adult female kangaroo is capable of pausing her pregnancy, stopping the newborn growth in a suspended animation. This generally happens when the female kangaroo is busy caring for another newborn baby.

The power involved within a single kick from a kangaroo is known to kill adult humans. The sharp claws on their hind feet can easily disembowel almost any animal.

Despite being a long-running joke, the kangaroo does have a fifth leg – kind of. They use this fifth appendage to balance their large bodies while hopping. This appendage is their muscular tail.

During a fight for dominance between two males, the sub-dominant male can be seen kicking. The dominant male tends to use their “fists.”

The birth of a kangaroo is considered one of the most bizarre in the entire animal kingdom. At the seven weeks, a pink worm enters the female birth canal of the kangaroo. This creature must grab onto the mother with barely there front legs and climb up into the thick fur of her front pouch.

Upon reaching the pouch, the kangaroo worm will permanently attach to a nipple for around 34 weeks. As it grows, the baby joey will detatch itself and attach to another nipple.

A lot of joeys won’t leave the mother’s pouch for eight months after first entering in. By this point, they are relatively mature, covered in fur, and can hop around.

The red kangaroo is capable of jumping 10 feet into the air and 25 feet forward. Add this to their impressive 40 mile per hour run speed and the kangaroo is a terrifying creature.

When a baby kangaroo falls from the mother’s fur, it is generally too small to survive. The mother will often abandon the baby. If she were to pick it up or move it, the baby would be crushed.

A kangaroo is known to defend themselves by leading their attacker into water and attempting to drown them, oddly enough.
