Interesting Facts

Unsegmented worms are generally parasitic rather than the free-living members of their phylum. Parasitic round worms include hookworms, trichinosis-causing worms, filarial worms, and eye worms.

-Hookworms are serious human intestinal parasites that are found in southern United States and cause weakness and poor growth to its host.

-Trichinosis is a disease caused by the roundworm Trichinella. These roundworms damage muscle cells and other organs that cause terrible pain for the host.
