Banco Chinchorro is anatollreef lying off the southeast coast of theMunicipality ofOthón P. Blanco inQuintana Roo,Mexico, nearBelize. It was featured throughout the 2009 semi-documentary filmAlamar by Pedro González-Rubio.[citation needed]
The reef lies in Mexican waters 35 kilometres (22 mi) offshore in theCaribbean Sea, or about 80 kilometres (50 mi) east of the city ofChetumal. It is approximately 40.2 kilometres (25.0 mi) long from north to south, and approximately 16 kilometres (9.9 mi) wide at its widest point. It covers an area of 800 square kilometres (310 sq mi). The atoll has three islands, with an aggregate land area of 6.7 square kilometres (2.6 sq mi):
The natural vegetation of the islands is largelymangrove near the shore shading into open woodland more than 20 to 30 metres (66 to 98 ft) from the shore. There is anAmerican crocodile reserve on the southernmost (and biggest) island. The islands (in common with many isolated tropical islands) are thickly populated with small crabs, which are tame and can be trodden on inadvertently by visitors.
Some of the islands are inhabited by fishermen, who live instilt houses about 60 to 100 metres (200 to 330 ft) offshore to circumvent local regulations forbidding private construction.[2]
The reef is home to at least nine shipwrecks, including two Spanish Galleons. The names of the known wrecked ships are: SSCaldera, SSEscasell, SSFar Star, SSGinger Screw, SSGlen View, SS Penelopez, SSSan Andreas, and SSTropic.[citation needed] There is also a large ferry fromCozumel that washed up on Chinchorro duringHurricane Wilma.[citation needed]
