Nematoda Animalia Flora and Fauna

Nematoda Animalia Flora and Fauna

Nematodes are the second most diverse animal phylum (after the arthropods), with about 20,000 species. Free-living nematodes are abundant in soils and sediments, where they feed on bacteria and detritus. Some nematodes are plant parasites, including organisms that cause disease in economically important crops. Others parasitize animals (including humans). Well-known parasitic nematodes include hookworms, pinworms, Guinea worm (genus Dracunculus), and intestinal roundworms (genus Ascaris).Most nematodes are long, slender, almost featureless externally, tapered at both ends, and round in cross section.
