Nematoida is a large group of worms including the Roundworms and Horsehair worms [1]. Some species are parasitic while other species are free living. Most species in the group are microscopic though most horshair worms and some nematodes are alot larger. All of the worms in nematoida have a cuticle made of collagen and a simmilar body shape. The groups placement is an argument as some scientists believe its closely related to panarthropoda while some scientists place it in a clade called Cycloneuralia which places them with Priapulid worms, Loricifera, and the Mud dragons.
