The Australian paralysis
tick (Ixodes holocyus) is roughly
confined to a 20-kilometre band that follows the eastern coastline of Australia. As this is where much of the human
population resides, encounters with these parasites are relatively common.
Although most cases of tick bite are uneventful, some can result in muscle
weakness, blurred vision, drowsiness, paralysis and even death by burying itself
in a person's skin and injecting a neurotoxin.
