| − | *Bursate

| − | *Most members of this superfamily look like short lengths of cotton (typically 0.5-2cm)
| |
| − | *The spicules of each species have a characteristic shape
| |
| − | *The heads have no distinct features

| − | == General Life-Cycle ==
| |
| − | *The egg is approximately 80µm long, oval, thin-shelled, contains 4-16cells (i.e. it is a typical strongyle egg)
| |
| − | *Egg → L1 → L2 → L3 (this occurs on the ground)
| |
| − | *L1 and L2 feed on bacteria
| |
| − | *L3 is the infective stage
| |
| − | *L3 is ensheathed (i.e. the L2 cuticle is retained after moulting as an "outer skin")
| |
| − | *L3 cannot feed, but contains a finite amount of stored food to provide energy for movement
| |
| − | *Infection is by ingestion of the L3
| |
| − | *L3 → L4 → adult (this occurs in the stomach or small intestine)
| |
| − | *Parasitic development initially occurs in gastric glands or intestinal crypts (depending on species)
| |
| − | *Adults are situated on the mucosal surface
| |
| − | *The prepatent period is typically about 3 weeks
