A survey showed that 91 percent of the reef experienced bleaching despite this year’s cooler, wetter conditions associated with the La Niña weather pattern.

The size and complexity of cephalopod brain structures differ depending on the habitats the creatures occupy, a study finds.

Both deep and shallow reefs are prone to bleaching, concludes a new study.

The reef has bounced back from “death events” in the past, but that doesn’t mean it will be resilient over the next few decades.

Not only did many corals die in recent years, but some were actually killed by the hotter temperatures themselves, rather than bleaching.

The near-complete feminization of northern Great Barrier Reef sea turtles has been blamed on climate change.

The decision to leave the United Nations’ educational, scientific, and cultural agency was spurred by what American officials say is the organization’s anti-Israel bias and lack of commitment to reform.

Aerial survey results reveal severe coral bleaching across much of the massive reef system.

High-resolution seafloor imaging revealed a much larger network of reef-like structures off the Australian coast than previously thought.

Researchers assess which parts of the Great Barrier Reef that have lost their vivid color are likely to die and which parts may pull through.

Researchers identify areas where marine ecosystems are faring better or worse than predicted in hopes of saving the world’s corals.

Scientists discover coral reef off the coast of Australia thriving at a record 125 meters (410 feet) below the surface.

Google Maps is adding panoramic images of coral reefs to its Street View option, allowing web surfers to better navigate the oceans.

Australian trout are susceptible to skin cancer, according to a new study—the first evidence that wild fish can be afflicted by the disease.

Scientists study a variety of large-scale biological phenomena from the vantage point of space.

Coral reefs are fraught with danger for herbivores such as damselfish and tangs. Venturing out from the safety of the reef’s colorful cracks and crevices to feed means risking being devoured by predators that patrol the warm waters. 

Scientists use Google Earth to observe the effects of predators on the feeding patterns of coral reef herbivores.
