A dolphin can produce as much as 5,400 watts of power; that鈥檚 roughly ten times more than the most fit human athletes produce, .

Previously, dolphins were thought to power through the water using a trick of fluid mechanics that enabled them to outswim boats moving at high speed. This theory held for the past 60 years until a researcher named Frank Fish : “Let’s see how much power a dolphin can produce.”

Using hydrodynamics models to look at the way a dolphin鈥檚 fluke propels it through the water, Fish discovered the secret to their speed. Using little more than a SCUBA tank and a garden hose, Fish measured power output as the dolphins swam through the corresponding bubble vortex.

The dolphins鈥 cruising speed produced a surprising 549 watts. That鈥檚 1.4 times the power a cyclist can sustain for an hour. When the mammals accelerated, that output jumped to 5,400 watts.

When asked what鈥檚 next, Fish responds, 鈥淚f I can do it for a dolphin, can I do it for a whale? Can I do it for a manta ray?鈥
