The Sea of Cortez is located in Mexico (also known as the Gulf of California) is a sea of striking beauty placed between the Baja California Peninsula and Mexico’s mainland.
The states of Baja California Norte, Baja California Sur, Sonora and Sinaloa all have coasts within this sea. Both Cabo San Lucas, The Corridor and San Jose del Cabo are cities with beaches located in this sea.
The name is in honor of Hernán Cortés, the conqueror of the Aztec Empire, who sent Francisco de Ulloa to map the area and sailed its perimeter between 1539 and 1540.
It was renamed the Gulf of California by the Mexican government.
The Sea of Cortez (Gulf of California) includes 244 islands and oceanic marine zones inscribed as World Heritage sites, it is also home to 891 fish species, 90 of them endemic (ie. only found in the Gulf).
These areas are also home to 39% of all the marine mammal species and 1/3 of the marine cetacean species (Thomson et al. 2000; Brusca 2002 PDF).

The Sea of Cortez has over 300 estuaries and wetlands that are home to a rich community of animal and plant species. They also are very important for the whole marine ecosystem in the Gulf generating a large number of nutrients and providing breeding and growth areas for innumerable living organisms.
It is also considered one of the seas with the highest biodiversity on the planet, and is, for example, home to more than 5,000 species of macro-invertebrates, it is also a bird watcher’s paradise and an important area for both bird migration, breeding and refuge.
The Sea of Cortez has been described as “ferocious with life” by John Steinbeck and as “the aquarium of the world” by Jacques-Yves Cousteau. They both make it crystal clear just how diverse life is in the area. Emphasizing this importance, UNESCO declared it a World Heritage Site and Biosphere Reserve. It is one of the most biologically diverse marine environments in the World, and they state: “The Sea of Cortez and its islands have been called a natural laboratory for the investigation of speciation”.
