tick

A group of arthropods belonging (with the mites) in the class Arachnida (the spiders). Ticks rest on tall leafy or grassy vegetation, generally in woodland or heath (but also in parks and gardens where other wildlife is present), and attaches itself to an animal, including a human, that brushes past. The tick punctures the skin and feeds on the blood. Ticks can transmit disease, the best known of which in Britain is Lyme disease.
