More Corals

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...
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...
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...
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...
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...
Discovered in 2004 and named in 2009, this Gersemia juliepackardae coral has been spotted and collected at several seamounts in the northeast Pacific Ocean at depths of 500-2,000 m (1,640-6,562 ft)...
J. Murray Roberts is a scientist who studies and maps an area of the cold-water coral called Lophelia in the North Atlantic, where the bases of some coral mounds are 2.6 million years old. Explore...
In this brief video clip from NOAA, catch a glimpse of the startling beauty and diversity of life found among deep-sea corals near the Aleutian Islands in Alaska. Explore more in the multimedia...
The toothy goby or common ghost goby ( Pleurosicya mossambica ) lives among soft corals and sponges in the Indo-Pacific ocean. The relationship it has with its host is commensal , which means the...
This specimen of the deep-sea coral Desmophyllum dianthus shows the visible bands that help marine scientists learn how ocean conditions changed over time. By looking at the thickness of each band,...
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...
Bikini Atoll, formed over millions of years around an island in the Pacific Ocean about halfway between Papua New Guinea and Hawaii, has been subjected to horrific human-caused disturbances. Between...
