General Appearance
- Bursate
- Large buccal capsule
- Relatively short (typically 1-5cm) but stout
- Heads often have characteristic features - teeth or cutting plates
General Life-Cycle
- Like that of the trichostrongyloids (eggs are also 'typical strongyle eggs'), but:
- L3 → L4 → adult (typically occurs in the large intestine)
- Larvae penetrate the mucosal wall and elicit nodule formation
- Larvae of some species migrate around the body
- Prepatent period varies between species from 3 weeks to over 6 months
