Photos by bertiegregory | Meet one of the most important animals on Earth: Antarctic krill. These tiny shrimplike crustaceans swarm in the millions and form the basis of the Antarctic food chain. Pretty much every predator in Antarctica eats krill: penguins, whales, albatrosses, fish, even leopard seals. A 2009 study estimated that Antarctica krill weigh between 300 and 500 million metric tons, making their biomass the largest of any multicellular wild-animal species on the planet.
