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.
People or animals infected by hookworms pass hookworm eggs in their feces. Larvae hatch from the eggs and are then accidentally swallowed by humans or animals by drinking infested water, for example, or enter the body through direct contact with the skin. Adult hookworms range in size from Â¼ to Â½ inch long.
