200 Pesos San Benedicto island

San Benedicto is one of the four Revillagigedo Islands, a Mexican archipelago roughly 700 km off the Pacific coast of Colima. The island was volcanically dormant until 1952, when an eruption destroyed the entire colony of Townsend's shearwaters nesting there — one of the few documented cases of a volcanic event driving a seabird population off an island entirely. The archipelago was designated a UNESCO World Heritage Site in 2016, largely on the strength of its marine biodiversity, including the resident oceanic manta rays that have made San Benedicto a fixture on technical diving itineraries.
