The australian paralysis tick (Ixodes holocyclus) produces neurotoxins that, as the name suggests, paralyze the host. Females are the most active, as they can feed on 6 to 30 days until they are engorged enough to support their young. Males usually use a host to find a female australian paralysis tick. After impregnating the female, the male generally dies. The female can lay up to 3000 eggs.

The eastern black-legged tick got its common name from its tendency to attach itself as a parasite to white-tailed deer. It is a vector for several animal and human diseases, including Lyme disease and Powassan virus. Humans are most likely to get bitten by ticks in the nymph stage, when they are smaller and hard to see. Humans also get bitten most often during the summer.

The castor bean tick (Ixodes ricinus) is known for carrying viral pathogens that cause Encephalitis and Lyme Disease. Much like other Ixodes, it has no eyes. Instead, they have sensory structures on their front legs and can smell a good host. They have a three-host lifecycle that lasts 2 to 3 years. Their hosts include horses, dogs, sheep, and humans.

The mature taiga tick favors the cold, temperate regions of its range, engaging in a parasitic lifestyle. Its complex lifecycle involves multiple stages, each seeking mammalian hosts, varying from small rodents to larger ungulates, and even humans, through which it can potentially transmit pathogens such as tick-borne encephalitis virus. Youthful stages frequently utilize smaller hosts, while adults may ambitiously target larger fauna to facilitate their reproductive cycle.

Ticks are temporary ectoparasites on the surfaces of the bodies of vertebrates and are also mediums for zoonoses. When they bite animals, they would also inject saliva with anesthetic effects, misleading the host to dismiss the harm they are creating. As the time span of the bite increases, the probability of contracting diseases increases as well.

The skin of cayenne tick is a unique natural marvel, capable of expanding several times its initial size to accommodate a blood meal from its host. As both nimble nymphs and diligent adults, they depend on a variety of mammals for sustenance, but display a marked preference for horses during their adult phase. This dietary specificity is essential for completing their complex life cycle.

The lone star tick (Amblyomma americanum) has a white dot on its abdomen. This bloodsucker has a taste for turkeys, giving it the nickname "turkey tick." They do not tend to be picky eaters, as they do latch onto humans as well. Humans that have been bitten by this often have Southern Tick Associated Rash Illness (STARI). Symptoms such as fever, headache, and joint pain are resolved quickly using antibiotics. 

Haemaphysalis longicornis, the Asian longhorned tick, longhorned tick, bush tick, Asian tick, or cattle tick, is a parasitic arachnid belonging to the tick family Ixodidae. The Asian longhorned tick is a known livestock pest, especially in New Zealand, and can transmit a disease called theileriosis to cattle but not to humans. However, the tick has been associated with several other tickborne diseases in humans. An unfed female is typically 2.0–2.6 mm long and 1.5–1.8 mm wide, and grows to 9.8 mm long and 8.2 mm wide with engorgement. Distinguishing a specimen from other members of the genus Haemaphysalis requires microscopic examination of minor physical characteristics.
