*Non-bursate
*Big fleshy worms; typically 5-40cm long (depending on age, sex and species)
*Three lips around the mouth
*A single-bulbed pharynx

== General Life-Cycle ==
*Adult females in small intestine lay eggs
*Eggs have a thick protective shell
*Some also have a sticky outer albuminoid coat
*Eggs passed in faeces
*L1 → infective L2 inside the egg
*Infection is by ingestion of the embryonated egg (egg in which a larva has formed)
*Eggs can remain viable in humid environment for up to 5 years
*After hatching in the intestine, the larvae of most species (but not all) undergo hepato-tracheal migration:
**egg hatches in intestine → larva penetrates intestinal mucosa → hepatic portal blood → liver → venous blood → heart → lung capillaries → alveoli → ascends trachea → swallowed → small intestine (where the adults develop)

NOTE: there are important variations on this theme; for example, the migratory larvae of some species can cross
the placenta or enter the mammary glands (examples of vertical transmission); while some species will utilise
paratenic or intermediate hosts.
