The world’s fastest fish is the Indo-Pacific sailfish, Istiophorus platypterus. This sport fish can swim up to 68 miles per hour by standards (a cheetah can run up to 70 miles per hour). Check out this incredible video from PBS which aired in August of 2010. Marine biologist, Rick Rosenthal, witnesses a rare moment of a sailfish feeding at night. You’ll also see a baby sailfish drawn into the light by Rick’s flashlight. Enjoy!
