A mushroom rock, also called rock pedestal or a pedestal rock, is a naturally occurring rock whose shape, as its name implies, strikingly resembles a mushroom. Usually found in desert areas, these rocks are formed over thousands of years when wind erosion of an isolated rocky outcrop progresses at a different rate at its bottom to that at its top. Such rocks are found in Thar Desert of India.

Andhra Pradesh has the second-longest coastline of 972 km among the states of India, the longest coastline being that of Gujarat (1600 km). This long coastline provides a nesting ground for sea turtles, the backwaters, such as those of Pulicat, are feeding grounds for flamingos and Grey Pelicans among several hundred other species of birds, and the estuaries of the Godavari and Krishna rivers support mangrove vegetation and habitats for several faunal species.
