A humpback whale and her newborn calf swim near Roca Partida, the smallest island of the Revillagigedo archipelago, off the Pacific coast of Mexico. During the mating season, the island waters are home to a large population of humpback whales, and are a popular diving destination.

The islands are volcanic and are themselves uninhabited, apart from a small naval presence. They were declared a biosphere reserve in 1994, and are currently under consideration as a UNESCO natural heritage site.
