Map & Background

Papua New Guinea (PNG) contains some of the world’s richest marine biodiversity. Not only does this island nation have more species of fish, invertebrates, and corals than any other marine region in the world, but it also supports a large population of threatened species, many of which can be found nowhere else. CORAL's main field site in PNG is located in Madang Province, east of Port Moresby on the northeast side of the island. PNG is one of the world’s major coral reef destinations, possessing an estimated 40,000 square kilometers of coral reefs, sea grass beds, and mangrove forests (jump to map).

Local PNG residents include: Sea Turtles, Manta Rays, White Bonnet Anemone Fish, Purple Eye Hovering Gobies, Hairy Ghost Pipefish, Fusiliers, Barracuda, Marlin, and Tuna. Due to its extraordinary diversity, PNG has become a growing attraction to divers from around the world.
