 =Basic Physical Description: = This species is known commonly as the pinworm, threadworm, and seatworm. It is small and white. The female worm has pointed posterior and is 8 to 13mm long, while; the male worm has rounded posterior and is 2 to 5 mm long.

=Habitat: = The pinworm is shown to infect humans all over the globe. Once the eggs are ingested they mature and move to the small intestine. The worm then moves farther down the digestive tract to colon and it mates. The females develop eggs and moves to the anus. The female then deposits the eggs and dies.

=Niche: = The pinworm is the most common parasitic worm infection in the Unites States and Western Europe. The infection is most widespread in small children. Usually if one person has the infection all the members of the household have it. It is spread by touching pinworm eggs and ingesting them, person to person, and sharing household items with an infected person.

=**Oddity:** = The female has to come out from the anus in order to receive oxygen so the eggs can mature.
