Over 400 species have been identified in the area, along with crocodiles, iguanas, and snakes, many of which are endemic to the region.

Another natural peculiarity of this corner of the Yucatán Peninsula is that the sea deposits millions of seashells on the coast, giving it a white appearance. In some places, limestone shell dunes are formed, contrasting with the characteristic low jungle greenery of the area.
