(nm´´td´), phylum consisting of about 12,000 known species, and many more predicted species of worms (commonly known as roundworms or threadworms).
Phylum: Nematoda
Members of this Phylum
Roundworms (nematodes) are bilaterally symmetrical, worm-like organisms that are surrounded by a strong, flexible noncellular layer called a cuticle. Their body plan is simple.
Phylum Nematoda, the round worms, contains parasites common to humans and domestic animals, including the species that causes heartworm in dogs. The vast majority of species is free-living (not parasitic) and harmless to humans.

Length Up to in (5 mm)
Depth Intertidal
Habitat Among algae in rock pools

nematodes (Phylum Nematoda from Gr. nema, nematos "thread" + ode "like") are one of the most common phyla of animals, with over 20,000 different described species (over 15,000 are parasitic).
The ecdysozoans also include the Nematoda or roundworms, perhaps the second largest animal phylum. Roundworms are typically microscopic, and occur in nearly every environment where there is water. A number are important parasites.

Parasites include species of intestinal protozoa (Ciliata), spore-producing parasitic protozoa (Apicomplexa), parasitic worms or flukes (Trematoda), tapeworms (Cestoda), roundworms (Nematoda), insects and fungi.
