Zooplankton

Overview

Zooplankton are the microscopic animals that are adapted to life in the open water. Most zooplankton are about 0.5 to 1 mm in length--just a dot to the human eye, but under a microscope they resemble tiny shrimp, a relative to zooplankton. Some are herbivorous, eating algae, or predaceous, eating other zooplankton.
