The Islands of the Gulf of California, also known as the Sea of Cortez, are a group of over 900 islands located between the Baja California Peninsula and mainland Mexico. These islands vary in size and habitat, ranging from rocky cliffs to sandy beaches, and are home to diverse wildlife, including sea lions, birds, and various marine species. Many of these islands are part of protected areas, such as the Islands and Protected Areas of the Gulf of California, a UNESCO World Heritage site. This designation helps preserve their unique ecosystems and promotes conservation efforts, making them important for both biodiversity and scientific research.
