this large insect, about the size of a human fist, was native to a number of planets. These creatures lacked true eyes and ears, and relied on their ability to sense vibrations in order to interpret their environment. These insects fed on the blood of mammalian species, burrowing into the thick fur of beasts such as the bantha and feeding for several months before killing the host. An individual tick can survive without blood for up to a year, curling into a ball to await the presence of a new host. Despite their hunger for blood, the most dangerous aspect of a sand tick is its ability to carry and transmit diseases. When the sand tick bites, it injects a small amount of numbing saliva, which can also carry viral and bacterial infections.
