Many regard the sailfish as the fastest fish in the sea. Built for speed, when swimming
at top speed it folds its fins close to its body so that it can slip smoothly through
the water. For short bursts, it is widely accepted a sailfish can reach 68 mph. However
recently some believe the powerful black marlin is a contender for the title. In
fact, in the above video clip, the presenter claims the black marlin he is trying
to catch and tag reached 80 mph.

Over long distances, tuna fish are the true speed champions of the ocean averaging
an impressive 45 mph. By comparison, the fastest speed a human swimmer can reach
is about 5 mph.
