Nematodes (round worms) include a number of important human parasites. Thirteen common rotifer species illustrate this diverse group of microscopic animals. Bryozoans have evolved remarkable filter-feeding strategies that are observed in freshwater and marine species. Gastrotrichs, tardigrades (water bears), nemerteans, and a recently discovered phylum, the gnathostomulida, acquaint students with many of the lesser-known branches of animal life.
