Researchers have discovered that algae called dinoflagellates can reproduce through sex. The finding could help protect corals from climate change.

Fish have pooped on reefs forever. But as climate change warms the seas, it's become a problem for coral, researchers say.

Healthy corals and mangroves break waves and dissipate their energy. Paired with unobtrusive hardened structures, they can provide powerful storm solutions.

During a 2015 heat wave, scientists watched as a coral reef died before their eyes. By the end of the century, almost all the world's corals will be gone if climate change continues at this pace.

A comparison of shark scales from a Panamanian coral reef 7,000 years ago to those today show shark populations have declined roughly three-fold.

Microscopic algae may evolve in tandem with the corals they inhabit, so each partner is fine-tuned to meet one another's needs, according to a new study.

New research suggests some corals have mangroves to thank for their ability to thrive.
