- Coloured scanning electron micrograph (SEM) of the head of the parasitic nematode worm Ancylostoma ceylanicum (Hook Worm) .
- Hookworms live in the intestines of their host. The head contains several tooth-like structures which it uses to cling to the intestinal wall. They are responsible for widespread morbidity and mortality in animals primarily due to their blood-sucking activities in the intestine. Larvae enter the bloodstream by ingestion or by skin penetration.
