The Coral Triangle reef is part of the so-called Ring of Fire, a 40,000 km volcanic belt that surrounds the land perimeter of the Pacific Ocean.
The Coral Triangle is home to the largest number of coral species on the planet.
Pelagic beings live in the so-called reef water column, the zone between the seabed and the surface. They are species that travel the sea placidly, feeding when they are hungry and swimming slowly throughout their lives.
