Kangaroos, iconic symbols of Australia, are unique marsupials known for their incredible hopping ability, reaching speeds up to 35 mph (56 km/h). They use their muscular tails for balance and can leap up to 25 feet in a single bound! Interestingly, kangaroos can't move backward due to their powerful legs and tail. They’re also social animals, often found in groups called mobs, and females have the amazing ability to pause their pregnancy until conditions are favorable, ensuring their joey's survival.
