Many parasitic nematodes possess free-living stages in their life cycles which feed and grow in an open environment in the same way as free-living organisms. The parasitic stage of the cycle is spent within the host. In Bunostomum trigonocephalum, which is a hookworm of sheep and goats, the parasitic stage inhabits the small intestine of the host, while Graphidium strigosum parasitises the inner wall of the stomach of the rabbit and hare. Both of these parasites are blood-suckers and reasons for their discrimination with regards to their foci are not fully established.
