Which is the typical feature of the hookworms related to the way they obtain food and explore the host?

Both Ancylostoma duodenale and Necator americanus have mouthparts with hooks or "teeth" that help the fixation of the parasite in the human intestine wall and facilitate the tissue injury essential to drain blood from the host. The structures are evolutionary adaptations for the parasitic way of life of these animals.
