In a world where bad news about the environment routinely outweighs good news, scientists have discovered an incredible exception: the world’s largest coral. Nestled in the pristine seas of the Solomon Islands, this huge marine monster is 34 meters broad and stands over five meters tall, dwarfing even the giant blue whale. It’s even visible from space.

“Just when we think there is nothing left to discover on planet Earth, we find a massive coral made of nearly one billion little polyps, pulsing with life and color,” said Enric Sala, National Geographic Explorer in Residence and founder of the Pristine Seas team that discovered the surprising find.

The mega coral, a species called Pavona clavus, is considered to be around 300 years old—a living time capsule that provides invaluable insights into past ocean conditions. Despite its majesty, scientists warn that it is not indestructible, with global warming and human activity posing immediate risks.

A discovery like no other

The coral was discovered during an expedition by the National Geographic Pristine Seas team, which works to advance ocean conservation. While exploring the southwest Pacific Ocean, they came across what looked to be a giant rock beneath the water. A closer look revealed that it was far more astonishing.

Even the local community was ignorant of its existence, which surprised the research team given its proximity to the ocean’s surface. This oversight demonstrates how much remains unexplored and unknown in the great blue depths of the ocean.

“This is a significant scientific discovery, like finding the world’s tallest tree,” Sala remarked. “But there is cause for alarm. Despite its remote location, this coral is not safe from global warming and other human threats.”

Solomon Islands: a coral wonderland

The Solomon Islands are renowned for their biodiversity, with the world’s second-largest number of coral species. The region’s seas are teeming with marine life, which includes over 490 different types of hard and soft coral.

This particular coral is not an exception. Its dome-like shape provides a safe haven for reef fish, crabs, and shrimp, helping to preserve the marine ecosystem.

“Large adult coral colonies like this contribute significantly to the recovery of coral reef ecosystems due to their high reproductive potential,” noted Eric Brown, coral scientist for the Pristine Seas expedition.

Despite warmer seas damaging surrounding shallow reefs, this coral has survived as a “beacon of hope,” growing in somewhat deeper waters with more stable circumstances.

What makes this coral so special?

The coral’s age and size are impressive, but its true worth is in the knowledge it contains. “It now stores information on how to survive throughout the centuries,” said Manu San Félix, an underwater cinematographer and expedition member who discovered the coral.

“The genetic code of these simple polyps is an enormous encyclopedia that has written how to survive multiple climatic conditions, and until now, it does so in the face of ocean warming.”

This coral has endured centuries of change, from the entrance of European explorers to today’s environmental difficulties. Its resiliency teaches important lessons about conserving marine ecosystems in a warming world.

Protecting the giants of the ocean

Currently, just 8.4 percent of the world’s oceans are protected in any way. Scientists say that findings like this highlight the importance of increasing marine conservation efforts.

The Pristine Seas team hopes that by studying this coral and others like it, they can uncover secrets that will help reefs around the world adapt to changing climates. Their research, which uses cutting-edge technology, has the potential to inform worldwide initiatives for protecting marine biodiversity.

Conservation, however, involves more than just science. It necessitates international collaboration, local participation, and public awareness. Discoveries like the giant coral highlight the ocean’s beauty, resilience, and vulnerability.

As the climate crisis worsens, this coral serves as both a beacon of hope and a sobering reminder of what is at stake. “It is a natural monument that has seen the arrival of the first Europeans to these waters,” San Félix said with pride.

If we can protect these ancient giants, we will preserve not only marine biodiversity but also a piece of our shared legacy. With the right action, this coral—and many others—can live for generations to come.
