Iron nematodes mate and lay eggs in the water, and the larvae in the eggs hatch into grasshoppers, crickets, cockroaches, beetles and other insects to develop into larvae. The insects enter the water, and the larvae leave the host and develop into adults in the water. Adults live freely in seawater or fresh water, and larvae are parasitic in arthropods.

The method of eliminating iron nematodes is generally to take anthelmintics and expel worms. Occasionally, it will be drilled into the internal organs and then surgically removed.

The best way to stay away from iron ascariasis is not to eat raw food, fish and snails, which is not very hygienic.

Iron nematodes are capillary nematodes or Auricularia aurea, and there are 250 ~ 300 species of linear classes or animals in marsupials. The body is slender, similar to horse hair, and the length can reach 1 m (about 39 inches). Adults live freely in seawater or fresh water, and larvae are parasitic in arthropods.
