Tick

Ticks are small arachnids in the order Parasitiformes. Along with mites, they constitute the subclass Acarina. Ticks are ectoparasites (external parasites), living by hematophagy on the blood of mammals, birds, and sometimes reptiles and amphibians. Ticks are vectors of a number of diseases that affect both humans and other animals.

Despite their poor reputation among human communities, ticks may play an ecological role by ailing infirm animals and preventing overgrazing of plant resources.

Taxonomy

Of the three families of ticks, one – Nuttalliellidae – comprises a single species, Nuttalliella namaqua. The remaining two families contain the hard ticks (Ixodidae) and the soft ticks (Argasidae). Ticks are closely related to the numerous families of mites, within the subclass Acarina (see article: Mites of livestock).

The Ixodidae include over 700 species. They are known as 'hard ticks' because they differ from the Argasidae in having a scutum or hard shield. This shield generally can resist the force of a human's soft-soled footwear, especially on soft ground; it requires a hard sole on a hard surface to crush the tick. However, stepping on an engorged tick, filled with blood, kills it easily, though messily. In nymphs and adults of the Ixodidae, a prominent capitulum (head) projects forwards from the body; in this they differ from the Argasidae. They differ too, in their life cycle; Ixodidae that attach to a host will bite painlessly and generally unnoticed, and they remain in place until they engorge and are ready to change their skin; this process may take days or weeks. Some species drop off the host to moult in a safe place, whereas others remain on the same host and only drop off once they are ready to lay their eggs.
