Hookworm head. Coloured Scanning Electron Micrograph of the head of the parasitic worm Ancylostoma ceylanicum, also known as a hookworm. This is an animal parasite that does not infect humans. The head of this worm contains several tooth-like structures with which the worm clings to the bowel of it's host. Hookworms 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. Magnification: x222 at 6x7cm size. Magnification:x350 at 4x5 inch size.
