Warm water of Palaos, a small archipelago in l' perhaps Pacific Ocean, hold the richest biological diversity and the majority of the coral reefs of planet. In this “cradle of diversity”, the marine biologists recorded 700 coral species and 1500 fish species. The coral reefs of Palaos started to develop d' million; years, when colonized coral polyps submerged of volcanic mountains. The tiny polyps produces a material which cemented them in place. Side by side, they built skeletons, hard external around their soft body, and when they died, the corals d' other skeletons built above d' them. Geologic forces finally raised the mountains of coral surmounted above by the sea, and all the talks the corals died. With time, new colonies built on slopes plus underwater reefs islands...

The second larger reef of barrier in the world s' raise sea-bed off the coasts of the Belize. A paradise for plunger, it is known for attractive formations of coral, fish myriad and d' invertebrates, and clearness d' exceptional water. On the side ocean this 160-mile-length reef is a popular tourist designation known under the name Lighthouse Reef. Here, crystalline water to fill famous Blue Hole, a crater of more than 1000 feet broad and a little more than 400 feet of depth. On the surface, healthy coral formations of the rim of this wonder in an amazement, but to a depth of 125 feet, neither corals, nor fish can be found. Instead of that, a plunger finds stalactites formed during l' glacial era, when the sea level world was much lower and Blue Hole was an underground cave. The hole is formed when the roof of the cave crumbled...

Surrounded by l' one of vastest extended from the sand world, Red Sea turns the banks d' an ecosystem which seems deprived of life. For this reason, much of people find qu' it is difficult d' to imagine that some of the ground richest coral reefs place starting from the floor of the sections of the North Sea. Marine Scientist Eugenie Clark n' does not have such difficulties: " So only I could plunge in a place in the world, I would choose Short-nap cloth Mohammed." Having studied the life in the Red Sea for more than four decades, it has estimated that this field represents best Red Sea many beauties marine. In 1980, Dr. Clark encouraged the Egyptian government to return the site a national park, an idea which became a reality in 1983...

At the beginning of Mars, still covers of snow of the lake Baïkal, its deep water under seals of three feet of thick ice. During two next months, under the sun of luminous spring, the ice to defrost itself slowly in a punctuated process of crackings n' is not without pointing out the noise d' weapons. As long as the ice remains in place, however, the scientists can set up right camp in medium this 400-mile-length, deep 5,000-foot-lake. Russia known as " lake sacré" is of 25 d' million; years, the oldest lake on planet. It is also the deepest lake, which holds more d' water that l' together Big lakes d' North America joined together. C' is the aquatic life includes/understands more than 1.500 animal species and 1.000 plant species, of which two thirds are endemic. According to scientific navy Andy Rechnitzer, Baïkal is diversified biologically than the other lakes, because l' water rich in oxygen circulates of its surface for its deep depths, a process related to geothermic chimneys probable...

The blackness of the night, on a moved back part of planet, a volcano enters in eruption. Thick plumes of what resembles Bulow black smoke from there. To escape covers magma the ground; mercury climbs with more 600o deep cracks F. formed around the volcano, and the seepages d' overheated water of their share. Local residents not evacuated the zone. Whereas the magma is mortal for them, l' warm water l' is not, and thousands are able to thrive in an apparently infernal habitat. L' eruption of violence, which lasts since weeks, n' is not typical of l' volcanic activity. It occurs to a sea deep-wind more than 8000 meters under surface of l' ocean...

The rise of the 600 miles of the Pacific with west of Ecuador are arid islands whose name, for obvious reasons, is a Spanish word for the tortoises. Indeed, the Galapagos Islands are famous for the tortoises weighing of the hundreds of books. Many people do not know, however, is that the attractive creatures also live in an underwater kingdom with the broad one. Describing contrast between the islands and their spoils in a submarine of the book 1924, Galapagos: World' S End, William Beebe wrote: " l' host of sally-lightfoots [crabs of tide] were the most brilliant points of color above of l' water in the islands, putting to make shame with the dull colours dull of the terrestrial organizations and referring to the glory of the animal life coloured under sea surface”...
