ticks are invertebrate animals in the phylum arthropoda, and are related to spiders. ticks are in the subclass acari, which consists of many orders of mites and one tick order, the ixodida. some mites are parasitic, but all ticks are parasitic feeders. ticks pierce the skin of their hosts with specialized mouthparts to suck blood, and they survive exclusively by this obligate method of feeding. some species of mites may be mistaken for larval ticks at infestations on animal hosts, but their feeding mechanisms are distinctive. all ticks have an incomplete metamorphosis: after hatching from the egg, a series of similar stages (= instars) develops from a six-legged larva, to eight-legged nymph, and then a sexually developed, eight-legged adult. between each stage is a molt (ecdysis), which enables the developing tick to expand within a new external skeleton. ticks are grouped in three families, of which two have genera of importance to domestic animals, as follows. the family argasidae contains the important genera "argas", "ornithodoros", and "otobius". these genera are known as soft ticks because their outer body surfaces lack hard plates. the family ixodidae contains 14 genera, including "amblyomma", "dermacentor", "haemaphysalis", "hyalomma", "ixodes", "margaropus", and "rhipicephalus". also, the important boophilid ticks, formerly of the genus "boophilus", are now classified as a subgenus within the genus "rhipicephalus". these genera are known as hard ticks because their outer surfaces have hard plates. within these genera are, very roughly, 100 species of importance to domestic animals. some of these species are also important to humans. the only countries that do not have some kind of problem with ticks on domestic animals are those that are permanently cold. an outline classification of the acari, including the two families of ticks of importance to domestic animals is in the article mites of livestock.
