Of the 400 or so shark species on the planet, the shortfin mako shark is thought to be the fastest, capable of swimming at speeds from 22 to 60 miles per hour. Makos are aggressive, however attacks on humans are rare because the species usually stays in the open ocean.

The theory that shortfin mako sharks can swim at high rates is based on the fact that makos may prey on swordfish and sailfish, which can swim at speeds over 60 miles per hour. However, researchers aren’t sure whether the makos could catch these fast fish while swimming at top speed, or whether they simply catch the fish off guard when swimming at a slower speed. In comparison, the fastest human can swim at a rate of 4.5 miles per hour.
