World’s largest creatures eat the worlds’ smallest creatures – it all happens in the ocean!

The world’s largest animals rely on the world’s smallest creatures for food, and they are all in the ocean. The blue whale is the largest animal ever to live on this planet (yes, bigger than any dinosaur). Phytoplankton (plant plankton) is the smallest creature, you can’t see individual phytoplankton without a microscope. Whales eat plankton, LOTS of plankton.
