Zooplankton are tiny, drifting animals found in freshwater and marine environments,

forming a vital link in aquatic food webs. They consume phytoplankton and, in turn, feed

larger predators such as fish and whales. Accurate identification of zooplankton species

helps scientists monitor ecosystem health, track environmental changes, and understand

biodiversity patterns.

The diversity of zooplankton is staggering — from copepods and cladocerans to larval

stages of various marine animals. Each group has unique morphological features that

require careful examination. This is where the University of Georgia’s guide shines by

breaking down these complexities into manageable sections.
