Since they are in the phylum Nematoda, hookworms have a psuedocoelom that they use for digesting food. -Hookworm eggs gain nutrients via the feces of the host that it has inhabited. -In the larval stage, hookworms are free-living in the soil.
Hookworm is most common in developing nations in Asia, sub-Saharan Africa, and Latin America. Areas with poor sanitation, water treatment, and plumbing/sewage infrastructure are especially at risk. The hookworm larvae live in the soil and migrate toward the surface in search of oxygen and sunlight.
