Zooplankton Biodiversity

Holozooplankton are animals that live adrift in the ocean waves for their entire lives. The researchers who took part in the Census of Marine Zooplankton, a project of the Census of Marine Life, spent a decade surveying and photographing holozooplankton biodiversity around the world. Here is a sampling of what they found.
