Zooplankton are a large, diverse group of organisms that live in the water column. Unlike most phytoplankton, they live at all depths, from the surface to the bottom. They come in many different shapes and sizes, and as the primary herbivores in the marine food web, they provide an important link between the primary producers and the carnivores.
