About This Dataset

Countries by Coral Reef Area

Countries ranked by the total area of coral reef ecosystems within their territorial waters, measured in square kilometres according to the World Resources Institute Reefs at Risk data. Australia has the largest coral reef system in the world — the Great Barrier Reef alone spans 344,400 square kilometres, making it the largest living structure on Earth and the only biological organism visible from space, though it has suffered significant bleaching events driven by rising ocean temperatures.

Analysis

Australia (344), Indonesia (51) and Philippines (26) take the top three in Coral Reef Area (Thousand km2). Values run from 344 at the top to 7 at the bottom, a spread of 337. Most of that gap is between first and second alone (293 of 337); the other 7 are separated by just 44. Only 1 of the 8 reaches even half the leader's figure (172 or more).
