I fail to see the necessity of (and, accordingly, I resent bitterly) all these coral-reef methods.
Our souls are islands, with a coral-reef of reserve built up about them.
But you said that the coal was made from plants and trees, and did plants and trees grow on this coral-reef?
Yet this glorious young hero was drowned—wrecked off a coral-reef, and flung like a weed on the waters.
No coral-reef breaks its ceaselessly-thundering rollers into surf, no palms wave their dark fronds in the blue.
It is not unfrequent that fossil remains of human bones and of animals are found embedded in the coral-reef limestone of Florida.
So I determined, if I could get a chance, to go down after some of those things on the coral-reef.
They remained apart from other species and appeared to prefer rocky beaches and coral-reef rocks to the sandy beaches.
You have a beautiful madrepore or brain-stone on your mantel-piece, brought home from some Pacific coral-reef.
Now, what I wanted to do, was to go to the coral-reef and dive down and get something for myself.
|coral reef |
A mound or ridge of living coral, coral skeletons, and calcium carbonate deposits from other organisms such as calcareous algae, mollusks, and protozoans. Most coral reefs form in warm, shallow sea waters and rise to or near the surface, generally in the form of a barrier reef, fringing reef, or atoll. Coral reefs grow upward from the sea floor as the polyps of new corals cement themselves to the skeletons of those below and in turn provide support for algae and other organisms whose secretions serve to bind the skeletons together. The resulting structure provides a critical habitat for a wide variety of fish and marine invertebrates. Coral reefs also protect shores against erosion by causing large waves to break and lose some of their force before reaching land. The Great Barrier Reef off the northeastern coast of Australia extends for some 2,000 km (1,240 mi), making it the world's largest coral reef.
A formation, at or near the surface of tropical waters, formed by skeletal deposits of corals, a form of sea life.
Note: Coral reefs form a protective environment for a wide variety of marine animals.
Note: Atolls — ring-shaped islands that nearly or entirely enclose a lagoon — are coral reefs.
Note: The largest coral reef is the Great Barrier Reef of Australia.
Note: Coral reefs are very sensitive to chemical pollution and changes in temperature and are considered to be in danger from environmental stress.
