what is the fastest water
In the water, fish take the lead. Sailfish are the fastest in the water, at 70 miles per hour (113 km per hour) â the same speed in the water as cheetahs attain on land. Mako sharks can reach 60 miles per hour (97 km per hour), and marlins, 50 miles per hour (80 km per hour). The fastest mammal in the water is the killer whale, which can swim at up to 48 miles per hour (77 km per hour). Neither insects, reptiles, mammals, or terrestrial bird speeds come anywhere close to birds in flight. Birds are not only the fastest animals in the air: they are the fastest on Earth.
