Ultraviolet light illuminates the growth rings in a cross-section of a 44-year-old deep-sea coral ( Primnoa resedaeformis ) collected off the coast of Newfoundland at about 1,300 feet (400 meters)...
A fan-shaped colony of red coral ( Corallium sp.) on the Davidson Seamount provides a perch for three basket stars as they feed. See more pictures of coral in our Deep-sea Corals article.
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...
Dr. Stephen Cairns is a research zoologist and chair of the Department of Invertebrate Zoology at the Smithsonian’s National Museum of Natural History. His research focuses on the diversity,...
The People's Reef, a part of the Hyperbolic Crochet Coral Reef , from above. The HCCR was created by Margaret and Christine Wertheim of the Institute For Figuring and is on exhibit at Smithsonian's...
New, white growth emerges from a living deep-sea coral sample that was stained pink, enabling ocean scientists to measure its coral growth rate. Find out more about how ocean scientists study deep-...
Deep-sea coral beds are true biodiversity hotspots. It’s urgent that we study these extreme environments because we know so little about them, because they are important communities for so many deep-...
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...
Flower-like zoanthids, relatives of coral, carpet a hydrothermal vent. This species of zoanthid is the first ever discovered at a hydrothermal vent. See more pictures of incredible deep sea diversity...
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...
Visitors to the Hyperbolic Crochet Coral Reef temporary exhibit at Smithsonian’s National Museum of Natural History saw both the main installation created by to the Institute For Figuring and the...
GEOMAR scientist Armin Form works at his lab during a long-term experiment on the effects of lower pH, higher temperatures and "food stress" on the cold-water coral Lophelia pertusa . In a previous...
A large white coral (Corallium sp.) grows on the Balanus Seamount, part of the New England Seamount chain. Hanging on to the coral are stalkless crinoids and orange brittlestars (Opiacantha sp.) To...
Close to the volcanic CO 2 seeps, the vast diversity of corals that exists in less-acidic waters is replaced by a "monoculture" of boulder corals. These are less fragile and better suited to life 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 ...
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...
How does a coral spend its day? Most of us would say: not doing much. To the human eye, a coral looks relatively still, waiting in the current and hoping some food will run into its tentacles. But...
Sometimes called the rainforests of the sea, coral reefs are incredibly diverse and complicated systems. Because of this complexity, it can be a challenge to manage and protect reefs—and sometimes...
