World’s largest coral discovered in the Solomon Islands
The largest coral in the world has been found in the Solomon Islands, and has been described by scientists as a "beacon of hope".
Measuring 32 metres long, the coral is visible from space and is three times larger than the previous record-breaker.
The 300-year-old coral is mostly brown but features splashes of bright yellows, blues and reds, and is covered with ripples of waves, mirroring the ocean’s surface.
At 34 metres wide, the organism is made up of a network of coral polyps, tiny individual creatures.
Eric Brown, coral scientist for the Pristine Seas expedition to the Solomon Islands, said: “Large adult coral colonies like this contribute significantly to the recovery of coral reef ecosystems due to their high reproductive potential.
“While the nearby shallow reefs were degraded due to warmer seas, witnessing this large healthy coral oasis in slightly deeper waters is a beacon of hope.”
It was discovered by scientists working aboard a research vessel in the southwest Pacific Ocean in October.
Unlike a reef which is a network of many coral colonies, the newly discovered structure is a standalone coral that has grown uninterrupted for hundreds of years.
The coral species, Pavona clavus, provides habitat, shelter and breeding grounds for an array of different animals from shrimp and crabs to fish.
Enric Sala, National Geographic explorer in residence and founder of Pristine Seas, said: “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 colour.
“This is a significant scientific discovery, like finding the world’s tallest tree.
“But there is cause for alarm. Despite its remote location, this coral is not safe from global warming and other human threats.”

Manu San Felix, Pristine Seas’ underwater cinematographer, was the first to spot the coral.
He said: “It is a natural monument that has seen the arrival of the first Europeans to these waters.
“Illustrious figures of humanity have coexisted with this colony: Newton, Darwin, Curie, Gandhi, Einstein, and it has survived them.
“It now stores information on how to survive throughout the centuries."
Despite its colours and size, to the naked eye the coral looks just like a giant rock beneath the ocean surface.
When the researchers initially spotted the coral they thought it might be remnants of a shipwreck due to its size, until one of the team dove down for a closer look and discovered it was an exceptionally big Pavona clavus.
