Shelves of coral surround the Pacific island of Palau.
Corals, small organisms related to anemones, secrete calcium carbonate, which hardens into an exoskeleton and over time forms reefs.

Appearing as flowers of the sea, the tentacles of an orange cup coral reach out in the waters of the Caroline Islands in Micronesia.
Known for their brilliant colors, these corals inhabit the shallow areas of coral reefs.

A Fijian reef explodes in color as a school of anthias swims past. If a soft coral hosts zooxanthellae (the algae that give coral the nutrients it needs to grow) and the water becomes too warm, the algae leave and the soft coral die.
Unlike hard corals, soft corals don't leave a limestone skeleton behind and cannot regenerate.

With alphabetic intent, this branching coral near the Turks and Caicos Islands in the Caribbean Sea seems to be spelling out a message.
The coral's hard calcium-carbonate skeleton provides the form, and the symbiotic algae they host create the color.

Glowing green fluorescent coral in Palau absorbs light at one wavelength and emits it at another. Scientists have found that corals with fluorescent properties can handle the effects of coral bleaching caused by warmer waters better than other corals.
This gives fluorescent corals an edge in protecting the symbiotic algae they host.

Shining bright, a juvenile wrasse takes shelter in anchor coral off Flores Island, Indonesia. While not all of the more than 300 species of wrasses are vibrantly colored, many exhibit striking coloration and patterns.
Some species even change their sex along with their color.

A coral reef near the Cayman Islands in the Caribbean showcases some of the enormous diversity found in the coral realm.
Sponges, finger coral, sea fans, and brain coral give shape and color to this reef. One coral wall can hold more phyla than an entire continent.

The temperate waters of the Great Barrier Reef off Australia's eastern coast support this coral found near Heron Island.
Actually a reef complex, the Great Barrier Reef consists of at least 2,800 reefs and stretches more than 1,250 miles (2,000 kilometers) from its northern to its southern end.

Vivid orange, pink, and white soft corals branch out from a reef in Papua New Guinea. Soft corals open up to the current to feed on plankton and give the reef some of its most colorful scenes.
Indo-Pacific coral reefs contain some 90 genera of soft corals.

Like dancers in formation, this group of soft coral shines green in the western Pacific. Soft coral polyps differ from hard coral polyps in that they have eight tentacles while hard corals have multiples of six.
Soft corals don't leave behind a hard skeleton when they die, as reefmaking hard corals do.

Black coral creates an undersea forest for colorful reef fish and can live for 300 years. Aiding its marine ecosystems by creating reserves, New Zealand hopes to protect 10 percent of its waters by 2010.

Flower coral in the Philippines demonstrate the derivation of their common name.
This close-up view shows off the coral's polyps. Brain, branching, mound, and plate corals describe other coral shapes and structures.
