The watery world of phytoplankton and zooplankton is a daily drama—an ocean teeming with plants and animals. It’s the ocean like you’ve never seen it before. Shrink down as we enter the ocean microworld and discover the strange, the beautiful, the indispensable—plankton.

Hey, teachers! Here’s a cheat sheet of what’s included in this episode of Microworlds:
