Ticks

Ticks are the small wingless external parasites, living by hematophagy on the blood of mammals, birds, and occasionally reptiles and amphibians. Ticks are blood-sucking parasites that are often found in freshly mown grass, where they will rest themselves at the tip of a blade so as to attach themselves to a passing animal. It is a common misconception that the tick can jump from the plant onto the host. Physical contact is the only method of transportation for ticks. They will generally drop off the animal when full, but this may take several days. Ticks have a harpoon-like structure in their mouth area, known as a hypostome, that allows them to anchor themselves firmly in place while sucking blood.
Ticks are important vectors of a number of diseases. Among the most imortant are babesiosis and anaplasmosis.
