The central part of the atoll Aldabra is a huge lagoon area of ​​about 272 square kilometers, which would easily fit the entire island of Mahe. Two times per day during low tide the water goes away from the lagoon. At high tide on four main channel wall of water rushes into the lagoon at a rate of almost 6 meters per second. Inbound water brings a variety of aquatic animals in the lagoon can be drawn even large manta rays and tiger sharks.
Tidal channels are divided into four coral atoll islands. Two large terraces rise above the sea level one to four, the other by eight feet. They represent two different phases of growth of corals and the subsequent stages of erosion, where the rocks can be sharp as a blade. Here and there protrude "mushroom" rock formations, the sea which gave form of the fungus. Here there are mangroves, live birds and other small animals.

The fauna of Aldabra is unique. The focus, of course, a giant tortoise. Here they were more than 20,000, five times more than the Galapagos Islands. They are concentrated in the southern part of the atoll - in Grande-Terre: the density of turtles - more than 650 individuals per square kilometer. Next to the turtle endemic bird aldabrsky shepherd, which on Aldabra has 5000 individuals.
Aldabrsky drongo (1500 individuals), are also endemic. These birds are found in the bushes and mangroves, feeding on insects, lizards and small birds. Another well-known bird - Coast Heron, whose feathers with age from white become black. On Aldabra lives and sacred ibis and great frigate, white-tailed Phaeton. So many different kinds of birds on the atoll attracts abundance and diversity of plants (198 species, of which 19 are endemic). The underwater world is no less diverse: corals, colorful algae, clams, mussels largest clams that can weigh over 200 kg. Fish predstavdena more than 190 species.

This group of islands - World Heritage Site since 1976, secured area with extreme Barrier Reef stretches for 500 meters. To save Aldabra struggle was long and hard. In 1954, the famous oceanographer Jacques Cousteau's ship "Calypso" sailed to the Aldabra observe nature, but this did not prevent the British government, which at that time belonged to prepare a draft of the atoll Aldabra turning into a military base to the port, airport, embankments, roads and buildings. Royal Society biologists have begun to explore the flora and fauna of Aldabra, began to protest, but they did not work. Aldabra was saved by a sudden: the British pound sterling was devalued, reduced military spending and funding for the project was abandoned.
On an island inhabited by a unique population (more than 152 thousand) of giant tortoises. Aldabra Atoll is completely surrounded by coral reef, cut by three passes, two more than the deep divide on the atoll of four large islands surrounding a large shallow, overgrown with mangroves along the edges of the lagoon area of ​​150 square kilometers, which, in turn, contains several islands. The largest of the islands - South, along with the West Island, Middle Island and Ile Polimnik they make up about 186 square kilometers land.

Most of the tropical islands for centuries been used intensively by man, but the Aldabra atoll was considered inhospitable and sailors in olden times it bypassed, so he managed to avoid wanton destruction, which have undergone. Many other secluded island group. He was not touched on the traditional collection of guano, coconut cultivation and the destruction of the environment associated with modern tourism. But to completely avoid the attention of human Aldabra atoll was not possible, and within the last 100 years it was the base of mangrove timber loggers, fishermen and hunters of turtles. As always, a man came to pets, but this invasion was limited to southern and western islands. The Government of Seychelles has declared the whole area of ​​strict reserve, in addition, it is the international security area.
As for all isolated oceanic island groups to Aldabra typical high percentage of endemic species. But more importantly, perhaps, that in a world where so little is left is really natural, Aldabra atoll is very close to this state.
Is dominated by two main types of terrain. One is found exclusively in the eastern part of the South Island: a rare shrubs, trees with sparse vegetation beneath them, and clumps of trees around a large freshwater Ozerets. The remaining space is occupied almost impenetrable thickets of thorns and the high dry grass.
Relative proximity of Aldabra as the African continent and Madagascar pozvodila to move on these oceanic islands larger number of species than might be expected. Aldabra has a surprisingly rich flora, with 273 species of flowering plants and ferns, of which 19 are endemic. Surprisingly rich in insects are represented here: registered more than 1,000 species, including 127 species of butterflies and moths, 36 of which live only here. Expand the list of endemic species of land snails and crustaceans, as well as the Seychelles flying dog aldabrskaya giant tortoise and freshwater fish that lives only in the rainwater.
Due to its isolation, the atoll was chosen for the nesting of many sea birds.
This is the main nesting grounds in the western Indian Ocean for small and large frigates, also is home to red-tailed and white-tailed carriages, red-footed boobies, white terns.
The most remarkable bird species al-Debre included, inter alia, aldabrskaya belozoby Warbler and the shepherd.
Aldabrskaya Warbler was discovered in 1968, and it is believed that the area of ​​its habitat is limited to a tiny portion of the coastal skreba. Able to watch it a few times, and it is certainly one of the rarest birds in the world. Belozoby shepherd, too, is endemic to Aldabra, is the only extant representative of a group of flightless birds, which included the extinct dodo.
Pulau yang sangat cantik. Tapi risau gak ada jerung. Siap boleh bagi makan kat black tip sharks lagi. Kalau ada yang kecil mesti ada yang besarkan tapi mungkin tak menyerang sebab ada sumber makanan yang banyak.
