Spirurida

Spirurida is an order of spirurian nematodes. Like all their relatives, they have neither a circulatory a or respiratory system.

The Camallanida are sometimes included herein as a suborder, and the Drilonematida are sometimes placed here as a superfamily.

Some Spirurida, like the genus Gongylonema, can cause disease in humans.
