If you’re anything like me, the first time you heard of krill was in Finding Nemo, right before Marlin and Dory get eaten by the whale, and since then you’ve heard about them here and there in nature documentaries, and they’re always getting eaten. Although it’s true that they’re basically always getting eaten, but don’t you go thinking that that means they’re not important. In fact, the reason they’re so important is the fact that they’re at pretty much the bottom of the food chain. Krill can be found in all the oceans of the world, and are a source of food for whales, fish, squid, penguins (and are in far higher numbers than a tow truck service could handle, let me tell you). In fact, if the krill in the Antarctic region were to disappear, most other species in the Antarctic would disappear. Krill make such good meals because they feed on plankton, the nutrients of which they convert into a form that can benefit their predators.
