Chagos Archipelago Gallery
Chagos is situated in the British Indian Ocean Territory (BIOT), about 500km south of the Maldives.
It is home to some of the most pristine coral reefs in the world, though a mass bleaching event in 1998 wiped out almost 90% of the coral population.
Today, Chagos is the largest Marine Protected Area in the world, and a benchmark for global marine conservation.
Take a look at some of the fantastic creatures the reserve is home to.
