Lithops are a type of succulent plant, they are part of the ice plant family. Lithops are also referred to as living stones because of their resemblance to small stones. This resemblance to stones is a clever camouflage technique to prevent them being eaten in their native southern African dry, gravelly, rocky plains. Because of their native habitat they need very different care to most succulents. Lithops make delightful little houseplants though and once their watering is taken care of they are a very easy care plant.
