A piece of the Institute For Figuring’s Hyperbolic Crochet Coral Reef known as the Ladies Silurian Atoll. The HCCR exhibit was on display in the Sant Ocean Hall at the Smithsonian's National Museum...
Lights attached to this modern deep-sea camera system enable scientists to capture detailed images of deep-sea coral reefs and their inhabitants in otherwise dark water. Learn more about how ocean...
A crown-of-thorns starfish ( Acanthaster planci ) on a reef in the Marianas Islands. An “outbreak” of these coral-eating starfish can decimate a reef, and they have done great damage on Australia's...
It is easy to feel hopeless when reading the news coverage of ocean conservation. Between climate change , acidification , pollution and overfishing, it often feels like the ocean and its...
I still haven’t gotten beyond the ‘gee whiz’ factor of studying communities of animals in deep-sea coral habitats. Climbing over undersea mountains and along the steep cliffs of submarine canyons...
In this photo of a shallow coral reef in the Pacific there are three species of forams . On the left, Peneroplis planatus . In the center, Amphistegina lessonii . And on the right, Laevipeneroplis sp...
Ocean scientists recently discovered this new species of black coral off the coast of southern California. It was named the “Christmas tree” coral, Antipathes dendrochristos , in 2005 because of its...
A squat lobster and blackbelly rosefish find shelter on a Lophelia pertusa coral reef off the southeastern United States. The Johnson-Sea-Link submersible captured this image in 2009. Explore more in...
Large numbers of grey reef sharks ( Carcharhinus amblyrhynchos ) were observed at Jarvis Island, an uninhabited Pacific island, during the 2010 Pacific RAMP expedition of the NOAA Ship Hi'ialakai ...
An orange brisingid starfish sits on a large reef of Lophelia pertusa, cold-water corals in the Gulf of Mexico, at 450 m depth as a school of fish swims above. They have many arms—up to 20!—covered...
You may not think of the ocean as a pharmacy but scientists are developing exciting new medicines from the sponges, corals, and other marine organisms found in the sea. Explore other videos that...
In the past 30 years, the Great Barrier Reef -- Australia's iconic natural wonder -- has lost half of its coral to a combination of forces. Dr. Nancy Knowlton, Sant Chair of Marine Science at the...
While bottom trawling—a fishing method that drags a large net with heavy weights across the seafloor—fishermen often catch more than their target fish. Here, they've scooped up a large deep-sea coral...
Researchers can study ocean acidification in the lab by rearing organisms in seawater with variable pH and measuring if they grow, eat, breathe, reproduce, or develop differently. It's common, for...
A coral ( Montastraea faveolata ) has just spawned. Each of the hundreds of polyps living in the colony releases a small pink bundle of sperm and eggs. Read more about coral spawing and watch a...
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...
A thicket of white stony coral ( Lophelia pertusa ) shelters a squat lobster (Eumunida picta). This is the typical shape of this widespread species of deep-sea coral. See more pictures of coral 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...
