This giant measures about 32 metres in length and 34 metres in width; its age is estimated at around 300 years. The coral is three times larger than the previous record-holder (known as Big Momma) and is the size of five tennis courts.

On an expedition to the Solomon Islands, divers affiliated with National Geographic have found the world’s largest single coral colony ever recorded. It’s longer than the largest blue whale. At 34 meters (111 feet) in length, and with a width of 32 (105) meters, it could sit corner to corner across 5 tennis courts.
