description The Coral Triangle Overview

Reefs across parts of Indonesia, Malaysia, Papua New Guinea, the Philippines, Solomon Islands and Timor-Leste form the Coral Triangle. Often called the Amazon of the Seas, this region is recognized for exceptionally high diversity of reef-building corals and reef fish. Its habitats support interconnected marine ecosystems and provide nursery areas for fish that matter to coastal livelihoods and commercial fisheries. The region is especially relevant to marine researchers and conservation groups studying how species-rich tropical seas function.

Its distinction is the concentration of marine diversity across a broad area, rather than one protected reef or a single destination. Coral bleaching and overfishing threaten that ecological richness. Protecting reefs therefore involves both the condition of the habitat and the way people use its resources, with local food supplies closely connected to the health of the sea.

help The Coral Triangle FAQ

Which countries are inside the Coral Triangle?

The Coral Triangle spans waters around Indonesia, Malaysia, Papua New Guinea, the Philippines, Solomon Islands, and Timor-Leste. That six-country region is known for exceptionally high coral and reef-fish diversity.

Why is the Coral Triangle called the Amazon of the Seas?

The nickname refers to its extraordinary marine biodiversity, especially coral reefs, reef fish, mollusks, and other tropical species. Like the Amazon rainforest, it is treated as a global biodiversity hotspot rather than just a regional habitat.

What animals are people most likely to associate with the Coral Triangle?

The region is associated with reef fish, sea turtles, sharks, manta rays, and some of the world's richest coral reef systems. Famous diving areas such as Raja Ampat in Indonesia are often used as examples of that biodiversity.

What are the biggest threats to the Coral Triangle?

Major threats include coral bleaching linked to warming seas, destructive fishing, coastal development, and pollution. Because millions of people in the region depend on reefs for food and income, conservation has both ecological and economic stakes.
