Ticks are parasitic arachnids that wait in vegetation or on rocks or logs for an animal or human to brush up against them. Once contact is made the tick will attach to its host by anchoring into the skin using hook-like mouthparts. Ticks may carry diseases transmittable to humans such as Lyme Disease and should be avoided.
