Did you know that kangaroos are the only large animals that use hopping as their primary form of movement? Their powerful hind legs allow them to travel long distances quickly, reaching speeds of up to 30 miles per hour. Interestingly, they can also maintain a steady pace without getting tired, thanks to their unique, energy-efficient hopping. Their large tails also help with balance while hopping. Kangaroos are herbivores, primarily eating grasses, and live in groups called mobs, which offer protection from predators. Each species has unique traits, but all are perfectly adapted to Australia's harsh environment.
