This suborder includes (superfamily - included families):

Major families[edit]

Diaphanocepaloidea[edit]

These are parasites of lizards and snakes. They have a direct life cycle in soil.

Ancylostomatoidea[edit]

These have very large buccal cavities. They infect the small intestine of mammal carnivores by skin penetration.

Strongyloidea[edit]

These have large buccal capsules with corona radiata. Most of them infect the large intestine by oral ingestion of the larva.

Trichostrongyloidea[edit]

These worms have very small mouths and are found in a large number of hosts

Metastrongyloidea[edit]
