Mesoamerican Barrier Reef System

Mesoamerican Barrier Reef System, Quintana Roo, Mexico

The Mesoamerican Barrier Reef System (MBRS), also popularly known as the Great Mayan Reef or Great Maya Reef, is a marine region that stretches over 1000 km from Isla Contoy at the tip of the Yucatán Peninsula down to Belize, Guatemala and the Bay Islands of Honduras. The reef system includes various protected areas and parks including the Belize Barrier Reef, Arrecifes de Cozumel National Park, Hol Chan Marine Reserve (Belize), Sian Ka'an biosphere reserve, and the Cayos Cochinos Marine Park. Belize's coastline, comprising the Belize Barrier Reef, is home to approximately 80% of MBRS. The Belize Barrier Reef is the largest barrier reef in the northern hemisphere and the second largest barrier reef in the world. The Belize Barrier Reef and Belize's 3 offshore atolls, several hundred sand cays, mangrove forests, coastal lagoons and estuaries - collectively termed, the Belize Barrier Reef Reserve System has been designated a World Heritage Site by UNESCO (1996).

Location

The reef system extends along the coast of four countries: Mexico, Belize, Guatemala, and Honduras. It begins near Isla Contoy on the northern tip of the Yucatán Peninsula and continues south alongside the Riviera Maya including areas like Cozumel and Banco Chinchorro. It then continues south down the eastern coast of Belize including many cayes and atolls. It extends past the north-east corner of Guatemala and ends near the Bay Islands of Honduras.

Biodiversity

The reef system is home to more than 65 species of stony coral, 350 species of mollusk and more than 500 species of fish.^[1][2] There are numerous species that live in or around the reef system that are endangered or under some degree of protection, including the following: sea turtles (Green turtle, Loggerhead Sea Turtle, Leatherback turtle, and the Hawksbill turtle), the Queen Conch, the West Indian Manatee, the Splendid toadfish, the American crocodile, the Morelet's Crocodile, the Nassau grouper, Elkhorn coral, and black coral.

The reef system is home to one of the world's largest populations of manatees, with an estimated 1,000 to 1,500 of them.^[2]

Some northern areas of the reef system near Isla Contoy are home to the largest fish on the planet, the Whale shark.^[2] The normally solitary Whale sharks congregate there in social groups to eat and to mate.
