Blue Shark

The blue shark’s sleek, tapered body makes it a graceful swimmer. Its elongated tail provides swimming power as it moves side-to-side. This shark is among the fastest swimming of the sharks and probably among the fastest swimming of all fish. Estimates of its speed vary, but some say that it can swim at about 60 miles per hour (97 km/h).
