Exclusive photos reveal a sprawling, 300-year-old coral near Solomon Islands, recently discovered by the National Geographic Society’s Pristine Seas expedition team.

Scientists said on Thursday they found what is believed to be the world's largest coral, which has been growing undisturbed in the Solomon Islands for possibly 300 years.

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.
