Mites and Ticks are Acari found across the polar regions to sulphur springs; from deep mines to fresh water and even in seawater. Practically, no biome is Acari-free. After bacteria, they are the most successful organisms on the planet. They have adapted for both free-living as well as parasitic lives. Mites have given up their predatorial quest and tend to be plant-feeders or scavengers while Ticks are predators and bloodsuckers.
