Arrecifes de Cozumel National Park is a protected area located on the island of Cozumel, off the coast of the Yucatán Peninsula in Mexico. The park is home to a diverse array of marine life, including over 500 species of fish and dozens of species of coral. It is also an important nesting site for sea turtles. The park was established in 1996 with the aim of protecting and conserving the coral reefs and other marine ecosystems in the region.
The reefs in the park are part of the Mesoamerican Barrier Reef System, the second-largest coral reef system in the world, after the Great Barrier Reef in Australia. The park is a popular destination for diving and snorkeling, and it is an important economic resource for Cozumel and the surrounding region, providing income from tourism and fishing. Arrecifes de Cozumel National Park is under threat from a variety of environmental stressors, including pollution, overfishing, and climate change, which can lead to coral bleaching and the spread of diseases such as white band disease and white pox disease.
