Most reef-building corals contain photosynthetic cells called zooxanthellae that live in their tissues. The corals and zooxanthellae have a mutualistic relationship. This means there is a positive ...

Coral isn’t really a plant, an animal or a mineral. Instead, it’s more of a complex relationship between all three. Researchers believed that the colorful mash-up first took place about 60 million ...

For the first time scientists have shown that corals hosting a single type of zooxanthellae can have different levels of thermal tolerance -– a feature that was only known previously for corals with a ...

Coral bleaching, which often results in the mass mortality of corals and in the collapse of coral reef ecosystems, has become an important issue around the world, with the number of coral reefs ...

A team of researchers from the Hawai'i Institute of Marine Biology (HIMB) have developed an interactive global map of corals and zooxanthellae as part of a hybrid web application titled GeoSymbio.

Forbes contributors publish independent expert analyses and insights. GrrlScientist writes about evolution, ecology, behavior and health. This article is more than 10 years old. Coral bleaching ...

While corals create habitats used by a diversity of marine life, coral bleaching can put that marine life at risk. Coral reefs cover less than 1% of the planet, yet over 1 billion people are estimated ...

O. arbuscula with a full complement of zooxanthellae had an assimilation efficiency of nearly 100%, compared to only 46% for corals containing few zooxanthellae. In A. pallida, symbiont density had no ...

ZOOXANTHELLÆ have been recorded from the visceral mass of Tridacna by Yonge 1, who assigned to them together with those of the mantle edge a very significant role in nutrition. According to this ...

When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white. Warmer water ...
