1Lençóis Maranhenses
Lençóis Maranhenses in northeastern Brazil is covered in rolling white sand dunes. During the rainy season, rainwater collects in the valleys between them, creating thousands of clear blue and green freshwater lagoons. Fish and other aquatic life thrive in these temporary pools. During the dry season, the water rapidly evaporates, but some fish burrow into wet mud beneath the sand and remain dormant there until the rains return.
