The Secret Life of Plankton is a one-of-a-kind look at the oceans’ gorgeous and supremely complicated microscopic ecosystems. Put together for TED-Ed by Tierney Thys, Christian Sardet, Noé Sardet and Sharif Mirshak, the footage does a fantastic job of showing how small, beautiful and terrifying the food chain can really get.
