Ocean scientists discovered this 1.5-m (5-ft) tall yellow bamboo coral in 2007 off the coast of Hawaii in 1,459 m (4,787 ft) of water. It is thought to represent a new genus. Learn about more deep-...
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...
Peter Auster and colleagues direct a Remotely Operated Vehicle (ROV) dive on the New England Seamounts. Three teams composed of three scientists and four ROV engineers take two 4-hour watches every...
Rockfish, anemones, and other invertebrates inhabit this deep-sea coral reef in Cordell Bank National Marine Sanctuary off the coast of California. Deep-sea corals provide habitat and benefits to a...
Found 1,751 m (5,745 ft) below the surface of Hawaii’s waters in 2007, this orange bamboo coral is 1.2–1.5 m (4–5 ft) tall. It is thought to represent a new genus. Learn about more deep-sea...
Tiny plant-like organisms called zooxanthellae live in the tissues of many animals, including some corals , anemones, and jellyfish , sponges, flatworms, mollusks and foraminifera . These microscopic...
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...
Reef sharks rarely get any love. These sharks, comprising several species, loiter around coral reefs, snacking on small fish, squids and crustaceans. And while their size is nothing to smirk at—5-10...

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...
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...
A coral hermit crab, Paguritta harmsi , about the size of two grains of rice, living in coral in the waters of Japan's Ogasawara Islands.
Searching for useful chemicals, marine scientists grow bacteria associated with deep-sea coral on nutrient agar to identify the bacteria and test their metabolic and biochemical capabilities. Some...
These corals are dead—smothered in sediments and overgrown with algae. The reef is near Komodo Island in Indonesia. More about coral reef ecosystems can be found in our Coral Reefs featured story .
Coral reefs are the most diverse of all marine ecosystems. They teem with life, with perhaps one quarter of all ocean species depending on reefs for food and shelter. This is a remarkable statistic...
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...
Nine years ago I was invited by a colleague to join a research team investigating deep-sea coral habitats . I was asked to examine the invertebrates associated with these ecosystems. After my first...
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-...
