Tuvalu is island group consisting of nine coral atolls in the South Pacific Ocean, about one-half of the way from Hawaii to Australia. See the link below for more information.
One and the moon is the largest
Generally, no. i suppose there are one or two .
I know of one. The Great Barrier Reef, located off the shore of Australia. It is supposedly the largest coral reef in the world.
Marine ecosystems are among the largest of Earth's aquatic ecosystems. They include oceans, salt marsh and intertidal ecology, estuaries and lagoons, mangroves and coral reefs, the deep sea and the sea floor. They can be contrasted withfreshwater ecosystems, which have a lower salt content.
The U.S. used the pacific atolls because they were isolated from large population centers and because the Marshal Islands (where many of these atolls were) were entirely under U.S. control after WW2, so could freely involuntarily evacuate indigenous populations of the atolls that testing was planned on. The USSR did all of their testing inland for security reasons (they also did not have control over any atolls). The British did much of their testing inland on Australia and some in the pacific on Christmas island. The French did their testing in the Sahara desert. The Chinese did all of their testing inland for security reasons. etc.

Limestone.
Just the one island.
The ostrich is the largest bird on Earth, and it is also a flightless one.
Coral reefs are one of the most diverse habitats on planet earth. They cover only about 1% of the ocean floor but are home to close to 25% of all marine life. They offer natural protection to Coastlines by creating breakwaters against storms. They provide a large revenue base for tourism. The largest benefit has yet to be realized. Coral reefs produce innumerable compounds, many of which have medicinal benefits. We are just beginning to understand the potential of these compounds.
