A tiny crustacean outweighs all eight billion humans on Earth
Individual Antarctic krill measure only about six centimeters in length, yet their collective population forms one of the largest animal biomasses on the planet. Scientists estimate their total mass at roughly 400 to 500 million metric tons—substantially surpassing the combined weight of all humans alive today. In the Southern Ocean, their enormous swarms are so dense they can be tracked from orbit by satellites.
