At 111 feet wide, 104 feet long, 18 feet high, and 600 feet around this stunning organism in the southwest Pacific Ocean is the world’s largest known coral that was discovered by accident. It is a conglomerate of individual creatures called coral polyps that have grown over 300 years. Instead of a coral reef like the Great Barrier Reef in Australia that is a network of several colonies, this is a standalone coral that has grown uninterrupted for hundreds of years.

It is a Pavona clavus and provides crustaceans and fish with shelter and a place to breed and live Divers from National Geographic Pristine Seas measure the world’s largest coral colony in the Solomon Islands.

Solomon Islands hosts the second highest coral diversity on Earth, with over 490 known hard and soft coral species.  A group of scientists working aboard a research vessel in the southwest Pacific Ocean has discovered the world’s largest coral in the Solomon Islands, 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.

But there is cause for alarm. Despite its remote location, this coral is not safe from global warming and other human threats.”   Corals provide reefs with a shelter, habitats, and place to breed.

However, team members initially thought that it might be a shipwreck due to its large size. When underwater cinematographer Manu San Félix dove down for a closer look, he realized it was a particularly big Pavona clavus. Despite the gargantuan size, the coral has never been documented.
