Within this nursery of the seas live 76% of the world’s coral species, 6 of the world’s 7 marine turtle species, and at least 2,228 reef fish species.

What is the Coral Triangle?

The Coral Triangle is the planet’s richest centre of marine life and coral diversity, with over 6,000 species of fish, 76% of the world’s coral species, and an awe-inspiring array of wildlife.

Resources from the area directly sustain more than 120 million people living here. But overfishing, destructive fishing, unsustainable tourism, impacts of urbanization, and climate change are fast eroding this resource base.

WWF is investing in the conservation of the Coral Triangle because of its outstanding biodiversity and because it is the source of food, livelihoods, and income for millions of coastal communities — but also a provider of ecosystems goods and services to a global population.
