More Corals

A marine scientist performs a genetic analysis on a sample of deep-sea coral to find out if it is a known species or one new to science. Find out how ocean scientists study deep-sea corals in our...
Thousands of seamounts—most of them undersea volcanoes—tower above the muddy seafloor. They provide something hard to come by in the deep ocean : a solid surface to cling to. This photo gallery shows...
Black corals, like this one growing on the Manning Seamount off the New England coast, often resemble bushes or trees. Contrary to its name, the living tissue of black coral can be one of several...
In this close-up photo, you can actually see the photosynthetic algae, or zooxanthellae, living inside a tiny coral polyp. Look for the brownish-green specks in the colorless polyp. Corals depend on...
We have arrived as the advanced scouting party to the scene of this year's field work location: Pemuteran, a small fishing village in northwest Bali. More importantly, we are sitting squarely at the...
Much of the carbon dioxide we emit into the atmosphere ends up in the ocean. As CO 2 levels rise, seawater becomes more acidic. This change in chemistry poses a serious threat to marine organisms...
Scientists at the Smithsonian and partnering organizations have discovered a remarkably primitive eel in a fringing reef off the coast of the Republic of Palau . This fish exhibits many primitive...
Corals, sponges, and algae are the major components of most coral reef communities. To the untrained eye, they are sometimes difficult to tell apart. More about coral reef ecosystems can be found in...
This bubblegum coral ( Paragorgia arborea ) has a fanlike shape. It is growing 1,310 m (4,298 ft) deep on the Davidson Seamount southwest of Monterey, California. Learn more about deep-sea corals in...
Views of each sonar beam appear on the left side of this computer screen image while the path being mapped by the ship appears on the right. These 3-D color images enable ocean scientists to locate...
American Samoa National Marine Sanctuary comprises a fringing coral reef ecosystem nestled within an eroded volcanic crater on the island of Tutuila, American Samoa. The 163-acre sanctuary—the...
See a few of the many species of deep-sea corals that have been discovered by scientists just since 2004. Learn about more deep-sea discoveries in our Deep-sea Corals article.
