Coral

Many people think of coral as hard, rock-like formations that attract abundant, diverse marine life. In fact, corals are themselves tiny marine animals called polyps that live together in large colonies.

Coral polyps are relatives of jellyfish and anemones. Some live in shallow water, some in deep; some form hard outer skeletons made of calcium carbonate, others have a soft body encasing hard internal structures known as sclerites. Hundreds of thousands of hard corals with their skeletons glued together form the iconic reef structures that do, indeed, serve as the foundation for important marine ecosystems around the world.

The Power of Super Reefs

For the First Annual World Reef Day, dive into this video about Super Reefs—coral reefs across the tropics that are able to withstand the stress of ocean warming, and can breed resilient larvae that can be used to reseed other reefs.

Virgin Island Corals in Crisis

A coral disease outbreak that wiped out nearly 80% of stony corals between Florida’s Key Biscayne and Key West during the past two years appears to have spread to the U.S. Virgin Islands (U.S.V.I.), where reefs that were once vibrant and teeming with life are now left skeleton white in the disease’s wake.

A DISCO in the Ocean

To investigate coral bleaching, WHOI scientists figure out a novel way to take direct measurements in the ocean of superoxide, a key molecule that vanishes almost as soon as it is made.

How Do Corals Build Their Skeletons?

WHOI scientists discovered precisely how ocean acidification affects coral skeletons’ a factor that will help scientists predict how corals throughout the world will fare as the oceans become more acidic.

Searching for ‘Super Reefs’

Some corals are less vulnerable to ocean acidification. Can the offspring from these more resilient corals travel to other reefs to help sustain more vulnerable coral populations there?

The Unseen World on Coral Reefs

We have learned that microbial communities on and within us—a microbiome—keep people healthy. Corals reefs also have their own microbiomes that they couldn’t function without.

A Double Whammy for Corals

Scientists know that gradually rising ocean temperatures can push corals past a threshold and cause them to bleach. But combine…
