Arrecife de Alacranes
Arrecife de Alacranes (Scorpion Reef) is a reef located 125 km north of the Yucatan Peninsula of Mexico. The reef is a designated national park that, because of its remote location, is visited only by serious scuba divers and very enthusiastic birdwatchers. The reef has five main islands, but only one is inhabited (Isla Perez). The park is recognized as an "Important Bird Area" because of its large nesting population of frigatebirds.

Understand[edit]
The reef system is 17 miles long by 13 miles wide. It sits in an area of open ocean in all directions which accounts for its reputation as a treacherous area for seagoing vessels. Many ships met their demise on the reefs, leading Lloyds of London to construct the lighthouse on Isla Perez in the mid 19th century. The light has subsequently been rebuilt and upgraded, though the lightkeepers house is the original structure built by Lloyds. The Mexican navy maintains a permanent garrison on the island.
Arrecifes de Alacranes National Park has been designated as a UNESCO Biosphere Reserve and as a Ramsar wetland.
Landscape[edit]
The islands are white coral sand and subject to changing geography due to seasonal storms and tidal variation. Many small islands are unvegetated sandy strips. There are five primary islands that do have vegetation, the largest of which is Isla Perez. The other four vegetated islands are Isla Desertora, Isla Pajaros, Isla Chica, and Isla Exterrado. The islands are primarily sand dunes and mangrove wetlands.
Flora and fauna[edit]
These landscapes are important nesting places for various bird species, including the endangered sharo-shinned hawk (Accipiter striatus), the peregrine falcon (Falco peregrinus) and the piping plover (Charadrius melodus).
Thirty-four coral species make up the reefs. Four species of sea turtle nest on the beaches.
Climate[edit]
The climate is hot and dry.
