Overview
Subclass Spiruria comprises mostly parasitic secernentean nematodes. In an alternate classification, they are treated as suborder Spirurina, with the orders listed here being ranked as infraorders.
The Ascaridida and the Oxyurida, which include worms that infect many mammals (including marine mammals), are sometimes placed in subclass Rhabditia. But that seems as spurious as the erstwhile placement of the in subclass Tylenchia. The Camallanida and Drilonematida are sometimes included in the Spirurida as suborder and superfamily, respectively.1]
Some important species
- Giant roundworm (Ascaris lumbricoides), causes ascariasis in humans
- Toxocara canis, parasite of dogs
- Anisakis, responsible for the human disease Anisakiasis

The Suborder Spirurina is further organized into finer groupings including:
- Family (16): Acuariidae · Aproctidae · Creagrocercidae · Drilonematidae · Filariidae · Gnathostomatidae · Hedruridae · Homungellidae · Mesidionematidae · Physalopteridae · Scolecophilidae · Setariidae · Spiruridae · Tetrameridae · Thelaziidae · Ungellidae
Families
Acuariidae
Acuariidae is a family of spirurian nematodes. Like all nematodes, they have neither a circulatory nor a respiratory system. They are the only family in superfamily Acuarioidea, and number about 40 genera and 300 species, most of which are parasites of birds.. [more]
Aproctidae
Creagrocercidae
Drilonematidae
Filariidae
Gnathostomatidae
Hedruridae
Homungellidae
Mesidionematidae
Physalopteridae
Scolecophilidae
Setariidae
Spiruridae
Spiruridae is family of nematodes in the order Spirurida. An unidentified parasitic larval member of this family has been recorded in the marsh rice rat (Oryzomys palustris) in a salt marsh at Cedar Key, Florida, and also in fiddler crabs (Uca) there; it is perhaps a bird parasite that does not reach maturity in the rice rat. [more]
Tetrameridae
Thelaziidae
Thelaziidae is a family of spirurian nematodes, which form the mid-sized lineage of the superfamily Thelazioidea. Like all nematodes, they have neither a circulatory nor a respiratory system. [more]
Ungellidae
More info about the Family Ungellidae may be found here.
