Rotifers are found in still waters, and there are over 2,000 species. They all have two crowns of cilia that work in sync to help them move and gather food. One of nine segments in a series, with all nine available on a DVD.

The diversity of rotifers is stunning, and many different species are overviewed. Planktonic rotifers have special adaptations for open water life. Nematodes (roundworms) include a number of important human parasites, seldom seen but easily found. Tree moss, leaf litter, and compost piles swarm with nematodes.
Part of the "Life in Aquatic Environments" series. Places many of the organisms into an ecological perspective of hydras, planarians, annelids, aquatic insects, rotifers, protists, and all other organisms that provide food for fish and other vertebrates. Observes adaptations for planktonic life in daphnia and other cladocerans, copepods, rotifers, and planktonic algae. Explores bacterial decomposition, recycling of materials, adaptations for bottom life, and ecological relationships in the bottom community. Takes an underwater look at the highly specialized organisms that live in rapids, under rock communities, and in slower waters. Investigates adaptations for life in temporary wetland environments.
