It’s more than 100 feet long, around 300 years old, made of nearly 1 billion little polyps and visible from space

The mega-coral measures 34 metres by 32 metres – making it larger than a blue whale – and it is thought to be three centuries old

The world's largest coral has been found in the Solomon Islands, a remote nation made up of hundreds of small islands in the South Pacific. It is enormous.

On Thursday, as a National Geographic expedition was exploring the waters around the Solomon Islands, its members spotted something that looked like a shipwreck underwater. Intrigued, they sent a diver down to investigate.

The largest coral in the world has been found in the Solomon Islands. The coral, which is visible from space, is three times larger than the previous record-breaker, and is believed to be about 300 years old.

The world's largest coral has been found in the southwest Pacific Ocean, and scientists say the massive organism is visible from space. The big picture: The "mega coral" near the Solomon Islands that's believed to be about 300 years old and measures 105 feet long by 111 feet wide was discovered by the National Geographic Pristine Seas team,

A group of scientists working aboard a research vessel in the southwest Pacific Ocean has discovered the world’s largest coral. Thirty-four meters wide and thirty-two meters long, the gigantic organism is a complex network of coral polyps—tiny individual creatures—that have grown over a span of three centuries.

Researchers have made a gargantuan discovery that’s as large as two basketball courts, visible from space, at least 300 years old and brimming with marine life: It’s the world’s largest coral, found in the southwest Pacific Ocean.
