nematodes
Unsegmented parasitic worms
Nematodes are microscopic worms, also called roundworms, that live in soil, water, and as parasites in plants and animals.
They are among the most abundant multicellular organisms on Earth.
Some species damage crops by feeding on roots; others cause diseases in humans and livestock, including hookworm and heartworm.
Beneficial nematodes help control garden pests.
