Kangaroos possess powerful hind legs, a long, strong tail, and small front legs. Kangaroos belong to the animal family Macropus, literally "big foot." Thanks to their large feet, kangaroos can leap some 30 feet (9 meters) in a single bound, and travel more than 30 miles (48 kilometers) per hour.
2. Shark
These majestic top predators that are so essential to the natural order of marine ecosystems now face their most severe threat from overfishing. Many species are threatened with extinction, with some families of rays such as sawfishes in peril. While sharks and rays have been an irreplaceable resource for coastal communities in the developing world for centuries, this unique balance is in danger of being lost forever.
