The plants blend in among the stones as a means of protection. Grazing animals which would otherwise eat them during periods of drought to obtain moisture usually overlook them. Even experts in the field sometimes have difficulty locating plants for study because of this unusual deceptive camouflage. In the wild, Lithops inhabit vast dry regions of southern Africa. Several areas in which these plants grow receive less than 2 inches of rainfall per month throughout the entire year. In an extreme situation of low rainfall, at least one species of Lithops depends on mist or fog to provide its main source of moisture . Lithops could not survive in many areas that they are found were it not for their capacity to store water. In fact, almost the entire plant is devoted to this function. The "body" of the plant is divided into two succulent leaves fused together in the shape of an inverted cone. The fissure or slit at the top of the plant is the division of the two leaves.
