Black Marlin – 82 mph

Though the black marlin may outrun the sailfish in terms of speed, one fish is said to have reached 82 miles per hour. The sailfish is regarded to be the fastest animal in the ocean. This fish, which is slightly larger than the sailfish at 15 feet long, is found in the warmer regions of the Pacific and Indian oceans. It weighs 1650 pounds, which makes it much heavier.

The black marlin's dorsal fin is lower and rounder than that of the sailfish, and its bill is considerably shorter. Its speed is even more astounding because its pectoral fins are so stiff that they cannot be flattened against the sides of the fish to reduce drag. The BBC released the 82 mph speed when a fisherman successfully hooked a black marlin on a line. They assert that the fish pulled the line off a reel at a rate of 120 feet per second, indicating a speed of 82 miles per hour. However, according to recent studies, the black marlin's current speed is a disappointing 22 miles per hour. If the black marlin's record speed was a hoax or not, only time will tell.
