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

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.

Now, the largest coral ever recorded has been discovered, scientists said Thursday, and it’s so big it can be seen from space. It was found by a National Geographic team conducting an expedition in the Solomon Islands in October to study ocean health.
