The Gulf of California, also known as the Sea of Cortez, is a narrow body of water located between the Baja California Peninsula and mainland Mexico. It stretches approximately 700 miles and is known for its rich marine biodiversity, including various species of fish, sea turtles, and marine mammals. The gulf is an important area for fishing and tourism. The gulf was formed about 5 million years ago due to tectonic activity, which created the rift between the Baja California Peninsula and the mainland. It is home to several protected areas, such as the Islands and Protected Areas of the Gulf of California, which aim to conserve its unique ecosystems and wildlife.
