Paracas National Park, a sparsely inhabited section of the South Peruvian Coast, is almost totally lifeless above ground and one of the world’s richest fisheries off shore. Barchan dunes start their march into the desert as the coast bends away from the direction of the Humboldt Current. Barchan Dunes can be construed as the largest life form of the desert, as they fulfill the technical definitions of a life form: by moving, growing, responding to stimulation and propagating.
