Like phytoplankton, zooplankton are usually weak swimmers and usually just drift along with the currents. Unlike phytoplankton, they do not perform photosynthesis and rely on other organisms for nutrition. Zooplankton include microscopic animals (krill, sea snails, pelagic worms, etc.), the young of larger invertebrates and fish, and weak swimmers like jellyfish

Most zooplankton eat phytoplankton, and most are, in turn, eaten by larger animals (or by each other).
Zooplankton are a type of heterotrophic plankton that range from microscopic organisms to large species, such as jellyfish
Zooplankton are found within large bodies of water, including oceans and freshwater systems. Zooplankton, a subset of the broader planktonic community, are heterotrophic organisms that inhabit both freshwater and marine environments The term “plankton” encompasses a diverse array of organisms that float or drift within aquatic realms. Explore zooplankton's role in aquatic ecosystems, behavior, diet, reproduction, and conservation status
Learn why they're vital for marine health! Zooplankton are small, often microscopic, heterotrophic organisms that float or drift in freshwater and marine ecosystems
