However, the tick has been associated with several other tickborne diseases in humans. Unfed female Haemaphysalis longicornis, ventral (underside) view, about 2.3 mm long. [4] 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. [5]
Tick paralysis is a type of paralysis caused by specific types of attached ticks. Unlike tick-borne diseases caused by infectious organisms, the illness is caused by a neurotoxin produced in the tick's salivary gland. After prolonged attachment, the engorged tick transmits the toxin to its host. The incidence of tick paralysis is unknown.
Ixodes uriae, also known as the seabird tick, is a species of parasitic tick known to infest marine birds. [1] [2] It is native to many high latitude areas in the northern and southern hemispheres including Alaska, Canada, Faroe Islands, Iceland, Greenland, England, Scotland, Norway, Finland, the Kola Peninsula, Russia, Patagonia, South Africa and Australia.
Colour and markings change markedly as engorgement progresses. It is the third tick, the moderately engorged adult female (width, at level of the spiracles, more than 4 mm) which is most commonly removed from dogs with tick envenomation. If a fully engorged tick is found on a dog, it suggests that the dog has a certain degree of immunity.
A third tick family, Nuttalliellidae, is less commonly discussed. [3] The primary distinction between soft and hard ticks is the amount of time they stay attached to their host. Soft ticks remain attached on the order of a couple hours and may take multiple blood meals from the same host.

Finding a site to feed typically takes a little as 10 minutes but can last as long as 2 hours. When the tick finds a sufficient feeding location it punctures the skin of its host and inserts a feeding tube that secretes a cement like substance and has barbs to help the tick to stay attached to the host.
Amblyomma americanum, also known as the lone star tick, the northeastern water tick, or the turkey tick, is a type of tick indigenous to much of the eastern United States and Mexico, that bites painlessly and commonly goes unnoticed, remaining attached to its host for as long as seven days until it is fully engorged with blood.
