General Appearance
- Bursate.
- Relatively short (typically 1-5cm) but stout.
- Heads often have characteristic features.
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 into mucosal wall and elicit nodule formation.
- Larvae of some species migrate around the body.
- Prepatent period varies between species from 3weeks to 6+ months.
