The Whale Sanctuary of El Vizcaino site in Mexico was inscribed on the World Heritage List in 1993. The sanctuary contains important breeding and wintering sites for the grey whale (Eschrichtius robustus - pictured here), harbor seal (Phoca vitulina), California sea lion (Zalophus californianus), northern elephant seal (Mirounga angustirostris), and blue whale (Balaenoptera musculus). The lagoons are also home to four species of endangered marine turtles: leatherback (Dermochelys coriacea), green (Chelonia mydas), hawksbill (Eretmochelys imbricata), and olive ridley (Lepidochelys olivacea).
Today, over 40 World Heritage sites are listed for their marine values. Together, they can be considered the "Crown Jewels of our Ocean" and are recognized for their outstanding beauty, exceptional biodiversity, or unique ecological, biological, or geological processes.
