Kingman’s Reef, Line Islands

This photo of Kingman’s Reef in the Line Islands shows what a healthy coral reef should look like. The water is crystal clear. A variety of richly colored corals carpet the seabed. And a native predator, a red snapper, prowls for prey. The reason why this reef is so healthy is that it remains isolated from human impacts such as overfishing and pollution.
