A noted marine explorer named Jacques-Yves Cousteau wrote: “It is all strange, unearthly, and yet familiar. Strange because the sea, once it casts its spell, holds one in its net of wonders forever.
Palau
The warm waters of Palau, a small archipelago in the Pacific Ocean, hold perhaps the richest and most biologically diverse coral reefs on the planet. In this “cradle of diversity,” marine biologists have recorded 700 species of corals and 1,500 species of fish.
Palau’s coral reefs began to grow millions of years ago when coral polyps colonized submerged volcanic mountains. The tiny polyps produced a material that cemented them in place. Side by side, they built hard, external skeletons around their soft bodies, and when they died, other corals built skeletons on top of them. Geologic forces eventually raised the coral topped mountains above the sea, and all the exposed corals died. In time, new colonies built more reefs on the islands undersea slopes.

The Galapagos Islands
Northern Red Sea
Surrounded by one of the world’s largest expanses of sand, the Red Sea laps the shores of an ecosystem seemingly devoid of life. For that reason, many people find it difficult to imagine that some of the earth’s richest coral reefs rise from the floor of the sea’s northern reaches..
Lake Baikal
Lake Baikal is known as the Galapagos of Russia as both share a history of spending many years in isolation from external world for very long period; if it was ocean that isolated Galapagos, it was the hostile permafrost of Siberia that cut Baikal from outside world. The flora and fauna of both lands had to evolve independently being cut off from mainstream animals and plants.
