Rocky Mountain Wood tick head. Coloured scanning electron micrograph (SEM) of the head of a Rocky Mountain Wood tick, Dermacentor andersoni. This tick is a carrier of the Colorado tick fever virus. The tick's specialised mouthparts (upper centre) are adapted to pierce the skin of its host. The tick is normally about 0.2 centimetres (cm) long, but grows to about 1.27 cm after a meal. Ticks are relatives of spiders, and have eight legs. Colorado tick fever is characterised by headaches, fever and body aches; it is rarely life-threatening. Magnification: x75 at 6x6cm size. | |
