It covers stretching over six municipalities in the Costa de Chiapas. It is composed of two large coastal lagoon systems that correspond to two core areas, and a wide variety of natural ecosystems including mangroves, zapotonales, tule swamps and marshes, as well as patches of tropical seasonal forest, coastal dunes and palm trees.
Eleven major rivers and their tributaries enter this ecosystem forming coastal lagoons where freshwater is mixed with sea water and the main activity is shrimp fishing. Biological diversity and richness of the site is extraordinary and includes a number of wildlife species such as jaguars, river crocodiles and alligators, spider monkeys, and more than three hundred species of birds, one hundred of which are migratory.
