First of all, the sprinter-cheetah
The speed of cheetah in sprint can reach 120 km/h(75 mph)! Cheetahs live a regular life, usually at sunrise and at sunset. They sneak up on their prey and then attack suddenly.
Second, the marathon runner-pronghorn
Pronghorn can maintain a speed of 60-70km/h (37-43mph) over a distance of 5km. Their body structure supports their long-term exercise, and their hearts are about twice that of domestic sheep. Pronghorn can usually catch up with their natural enemies easily. The speed is close to that of a cheetah, and its endurance is far better than that of a cheetah. The top speed is 80 kilometers per hour. One jump can reach 3.5-6 meters.
Third, super flying power-hummingbird
Hummingbirds fly fast and agile. Researchers at Stanford University once compared 12 hummingbirds with Black Hornet Nano, the world's smallest micro unmanned reconnaissance plane. Research shows that the wings of the red-throated hummingbird are 22% more efficient than the rotor of the reconnaissance plane.
Fourth, the diver-sperm whale
Sperm whales have strong diving ability, and they are the deepest and longest diving mammals. The giant sperm whale is the only mammal on the earth that can dive to a depth of 3000 meters and stay underwater for an hour, which is particularly surprising because whales have to reach the surface to breathe.
The significance of animal movement:
Can quickly find food, but also help to quickly avoid natural enemies; Increasing the scope of activities is conducive to finding a more suitable living space and occupying more abundant resources; Conducive to reproduction; Conducive to avoiding unfavorable environment; It can maximize the stress of organisms and make animals survive better.
