The largest coral ever recorded has been found by scientists in the southwest Pacific Ocean. The mega coral - which is a collection of many connected, tiny creatures that together form one organism rather than a reef - could be more than 300 years old. It is bigger than a blue whale, the team say.

National Geographic scientists say they’ve discovered the world’s largest coral near the remote Solomon Islands in the Pacific Ocean — an undersea mass that is so big, it can be seen from space.
