Mermithida is an order of nematode worms. The order includes two families, and most members are endoparasites on arthropods. One of the morphological characteristic of the order is the presence of a stichosome. [1] [2]
Mermithidae is a family of nematode worms that are endoparasites in arthropods. As early as 1877, Mermithidae was listed as one of nine subdivisions of the Nematoidea.

A venomous spider bite (like this brown recluse bite) can cause a red or purplish rash radiating from the site of the bite. There are only a few species of spiders in the U.S. that can bite humans.
Nematodes are very small, slender worms. Most are free-living, often less than 2.5 mm long and some only about 1 mm. Many nematodes are microscopic. Some soil nematodes can reach up to 7 mm in length, and some marine species can reach up to 5 cm. Some are parasitic and can reach lengths of 50 cm or more. [42]
