With their powerful, streamlined bodies, marlins are the fastest fish in the ocean, able to reach a speed equivalent to 80 miles per hour. This makesthem even quicker than the cheetah on land.
Marlins are not only able to accelerate quickly, in spite of water resistance, but they can also swim fast over long distances. This is thanks in part to the way in which blood flows around their body.Their circulation ensures that the body temperature remains several degrees above that of the surrounding water. When they are away from the shore, marlins swim in the upper part of the ocean where the sea is warmer, typically at a temperature of 68°F (20°C).
