    The Live Seafood Trade: A View from the Bottom

What is the Coral Triangle?

Born out of the collision of tropical light, warm sea temperatures and oceanic currents, this vast area of the Indo-Pacific region harbours 75% of all known coral species.

Nowhere else on Earth will you find 6 of the 7 marine turtle species, more than 3,000 species of fish, the heaviest bony fish of the deep (meet the 1,000kg mola) and the coelacanth: a species thought until recently to have gone extinct with the dinosaurs some 65 million years ago.

Much more remains to be discovered in the Coral Triangle.

For the people living in the Coral Triangle, the sea is more than just a source of food - it’s a way of life fostered across generations by a close dependence on the marine environment.

If the Coral Triangle fails as a large ecosystem, this dependence will unravel fast and both people and species will suffer.
