Mother Nature’s Olympians crowned


ChhetahThe Olympics is a time to celebrate the world's fastest and strongest humans, but you can rely on the International Union for the Conservation of Nature to put the best of human performance in perspective. They've just come out with their list of Olympians for the natural world — champions that range from the fleet cheetah to the humble fungus. “While celebrating the achievements of talented athletes across the world this summer, we should also take the time to appreciate these incredible species,” the IUCN says in today's Olympian roundup. Here are some of the conservation group's medalists for 2012:

Sprint: Cheetahs (Acinonyx jubatus) can bolt at 70 mph or more for short bursts, making them the world's fastest land animals. In comparison, Jamaican sprinter Usain Bolt is credited as the fastest human, with a top running speed of 27.79 mph. Theoretically, humans could reach velocities of 40 mph — still short of the cheetah's personal best.

High jump: To even things out, cross-species-wise, the IUCN is measuring jumping ability in terms of body length. By that measure, a lowly insect known as the common froghopper (Philaenus spumarius) gets the high-jump crown. It can jump 115 times its body length, while the record for humans is just a little over 8 feet (2.45 meters). That's about 1.25 times the height of the record-holder, Cuba's Javier Sotomayor (6-foot-5 or 195 centimeters).
