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...
The pearly razorfish’s name may be slightly misleading since it is neither as rare as a pearl nor as dangerous as a razor. It is a common fish that tends to live in clear shallow areas near seagrass...
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-...
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...
On March 1, 1954, the United States military tested nuclear bombs in the ocean around Bikini Atoll in the Pacific Ocean to see what kind of damage they would do to ships. The largest explosion was...

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...
Ocean acidification is sometimes called “climate change’s equally evil twin,” and for good reason: it's a significant and harmful consequence of excess carbon dioxide in the atmosphere that we don't...
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...
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.
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...
This colony of Lophelia pertusa was photographed from the Mingulay Reef Complex off Scotland in 2005. Learn more about the deep-sea coral reefs in our Deep-sea Corals article.
Come along as scientist Dr. Brendan Roark narrates a submersible dive to collect and study deep-sea corals. Roark studies deep-sea corals to understand the history of the ocean and past ocean...
Branching corals, because of their more fragile structure, struggle to survive in acidified waters that surround the volcanic CO 2 seeps of Papua New Guinea. Read more about how reef scientist...
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...
The New England Seamount Chain is the longest in the North Atlantic Ocean. It includes more than 30 major volcanic peaks. Seamounts provide a solid surface for corals and other marine animals to...
These deep-sea corals at the Madison-Swanson Marine Reserve in the Gulf of Mexico are protected, along with the marine life they harbor. Learn more about deep-sea corals and marine protected areas in...
Corals are sedentery animals, so how do they reproduce? One way is sexually through spawning , when the corals release eggs and sperm into the water (often at the same time due to some sort of...
