If marine biodiversity is what you are after, then look no further than the Coral Triangle. This remarkable patch of water spans the seas between the six Indo-Pacific nations of Indonesia, the Philippines, Malaysia, Timor-Leste, Papua New Guinea, and the Solomon Islands. The tropical waters of the Coral Triangle are among the most biologically diverse – and environmentally vulnerable – regions of the world. The Coral Triangle’s coral reefs, mangrove forests, and seagrass beds are home to vast numbers of fish, sharks and rays, as well as sea turtles and marine mammals.
