Santiaguillo is one of the 12 emergent platform type reefs that form the Southern Veracruz Reef System, located off the fishing village of Anton Lizardo in the western Gulf of Mexico. In 1992, the Mexican government declared the system a Natural Protected Area with a National Marine Park status. It is positioned approximately 20 km from the mainland and it is composed almost totally of coral rubble (no sand). It has an island associated with it that bears the same name, Isla Santiaguillo, which does not have vegetation except for Sesuvium.
