Scientists watched in real time as rising ocean heat transformed the sprawling reef. It was a harbinger for ecosystems everywhere as the planet warms.

Predators like parrotfish and pufferfish pose much more of a threat to young coral than previously believed.

Runoff from two Houston floods carried human waste onto coral reefs more than 100 miles offshore, research finds.

Human activity doesn't affect all species the same, according to a new global assessment that finds corals are the most affected marine organism on Earth.

Fish that dine on corals may pay it forward with their poop, which is jam-packed with all kinds of algae coral reefs depend on for survival.

Soundscapes of coral reef ecosystems can recover quickly from severe weather events such as Hurricane Irma in 2017, according to a new study.

Human-created noise can disrupt the behavior, physiology, reproduction, and ecosystems of whales and other ocean life. It can even lead to death.

But these 'cold-water coral' are threatened by accelerating sea currents.

A new method works like a blood test to identify heat-stressed corals that need protection from warming ocean waters linked to climate change.
