Animal Hall of Fame: Fastest
You won't want to challenge any of these animals to a race! Follow this slideshow to see how fast the cheetah, killer whale, peregrine falcon, and sailfish can travel.
The cheetah can run as fast as 70 m.p.h., and can go from 0 to 60 m.p.h. in just three seconds. These endangered animals only need to replenish themselves with water every three or four days.
Killer whales, or orcas, can reach speeds of 48 m.p.h. Killer whales travel in pods, and each pod has its own unique sound. They are members of the dolphin family.
The peregrine falcon dives at speeds of up to 200 m.p.h. and can fly at a rate of 90 m.p.h., making it not only the fastest bird, but also the fastest animal. Ostriches can run as fast as 43 m.p.h.
The Indo-Pacific sailfish can swim at speeds of up to 68 m.p.h. The top jaw of this fish extends well beyond the lower, forming a long spear.
