The Revillagigedo Archipelago, a chain of four volcanic islands in the Pacific Ocean near Mexico, is home to a spectacularly diverse community of sea life, including dozens of fish species found nowhere else on Earth. Mexico's President Enrique Peña Nieto recently designated these islands and the surrounding waters as a marine reserve and national park,prohibiting natural resource extraction, commercial fishing and development, to preserve the island ecosystems and marine life.

At Roca Partida, one of the four volcanic islands in the newly-protected Revillagigedo Archipelago near Mexico, several silky sharks (Carcharhinus falciformis) gather for mating rituals. At least 37 species of sharks and rays are found in waters around these islands.
Beauty in the depths
Off the coast of Mexico near the Revillagigedo Islands, carion angelfish (Holacanthus clarionensis) swim en masse.
A group of dolphins are seen swimming near the Revillagigedo Islands. These islands are volcanic peaks of a seamount — an underwater mountain range — which is home to diverse communities of fish, sea turtles, dolphins and whales.
A protected area
The newly-established Revillagigedo Marine Reserve lies about 240 miles (390 km) to the southwest of Cabo San Lucas, on the Baja California Peninsula's southern tip, and is made up of 57,177 square miles (148,087 square kilometers) of land and water.
A plethora of species
An estimated 366 species of fish and over 37 species of sharks and rays inhabit the waters around the Revillagigedo Islands in Mexico.
Beneath the waves
A group of divers explore the waters around Rosa Partida, one of the volcanic islands in the Revillagigedo Archipelago.
Off the coast of Mexico, coral reefs are home to many marine species in the waters around the Revillagigedo Islands. Reefs in protected areas have proven to be more resilient to climate change, and can even help repopulate ocean regions where corals are depleted.
A mature female and young male Humpback whale (Megaptera novaeangliae) swim in the waters off Roca Partida, one of the islands in the Revillagigedo Archipelago. Humpbacks migrate through these waters seasonally, lingering through the winter months.
The islands in the Revillagigedo Archipelago — Claríon, Roca Partida, Socorro and San Benedicto — are located in the Pacific Ocean near Mexico, and are uninhabited by humans except for two small naval bases.
