Last September, the Citizens of the Sea blog series brought you a story of doom and gloom from the reefs of Bocas del Toro, Panama. That is the time of year we typically study -- and celebrate -- the annual birth of baby corals in the area. We arrived to find very hot water (2010 turned out to...

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.
But most reefs don't have so many sharks. Read about it in the blog post "Reef Sharks Repelled by People...

A net used to trawl the ocean floor scooped up this large specimen of deep-sea coral. Because the ship was trawling for other species, the coral was discarded as bycatch. Fishing in deep-water habitats poses a major threat to deep-sea corals. Read more about vulnerable coral habitats in our Deep-...

What is coral bleaching? These white corals in the Gulf of Mexico’s Flower Garden Bank National Marine Sanctuary are bleached due to an increase in water temperatures, which causes corals to lose the microscopic algae that provide them with food. Bleaching spells trouble for coral reefs. Learn more...

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 cling to.

This colorful coral lives in Australia's Great Barrier Reef. On the whole, this coral reef is the largest single structure built by living organisms and can be seen from space! Although more than one-third of the reef is protected from fishing and other human impacts, it is still 50% smaller than...

Far away from the volcanic CO2 seeps, the water is unaffected and a healthy coral reef flourishes with a diversity of coral species. Closer to the seeps where the water is acidic, the corals barely even grow.
Read more about how reef scientist Laetitia Plaisance uses carbon dioxide seeps to study...

Compare the healthy coral on the left with the bleached coral on the right. Increased water temperatures caused the bleached coral to lose the microscopic algae that give the coral color and provide it with food. More about coral reef ecosystems can be found in the Coral Reefs section.

Scientists at the Smithsonian and partnering organizations have discovered a remarkably primitive eel in a fringing reef off the coast of the Republic of Palau. This fish exhibits many primitive anatomical features unknown in the other 19 families and more than 800 species of living eels, resulting...

Red coral necklaces fill a store display window. The United States annually imports around one million live coral animals from tropical reefs for use in aquariums, and is the largest documented consumer of precious red coral, commonly used in jewelry, according to a 2008 SeaWeb report (PDF).

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 trigger). External sexual reproduction occurs when colonies of coral release huge numbers of eggs and sperm...
