Deep beneath the waves of Southeast Asia lies an extraordinary region of unparalleled biodiversity known as the Coral Triangle. Dubbed the “Amazon of the Sea,” this underwater marvel spans over 5.7 million square kilometers and touches the shores of six nations: the Philippines, Indonesia, Malaysia, Papua New Guinea, the Solomon Islands, and East Timor. With its vast marine biodiversity, breathtaking coral reefs, and critical importance to millions of people, the Coral Triangle is a treasure unlike any other.

But like the Amazon rainforest, this underwater haven faces growing threats that jeopardize its survival.

The Coral Triangle: A Marine Biodiversity Hotspot

The Coral Triangle is home to an astonishing 764 species of coral, making it the richest marine biodiversity hotspot in the world. It harbors over 3,000 species of fish, more than double the diversity found in any other marine environment. This immense variety is supported by nutrient-rich waters that create a haven for life, including endangered species like sea turtles and manta rays.

The region’s coral reefs are also a major draw for marine tourism. Pristine underwater ecosystems offer some of the world’s most stunning diving and snorkeling experiences, attracting visitors from around the globe. This vibrant underwater world not only supports tourism but also provides vital resources for an estimated 120 million people who rely on the Coral Triangle for food, income, and cultural heritage.



The Coral Triangle is a marine area located in the western Pacific Ocean. It spans six countries: Indonesia, Malaysia, Papua New Guinea, the Philippines, Solomon Islands, and Timor-Leste.
