The soft-shelled ticks or Argasids are fewer in number. The one most known is Otobius megnini also known as the spinose ear tick. It is most common in the southwest and as one might guess, loves to attach itself and feed on ears. All ticks have three pairs of legs during the immature stage and four pairs as an adult. They crawl but cannot fly.
Wings are absent.
In addition, ticks possess a sensory apparatus called Haller s organ. This structure senses odor, heat, humidity, and you. This is how the ticks locate their food source. They climb upon tall grass and when they sense an animal is close by, they crawl on. A tick's diet consists of blood and only blood.
