Scientists say they have discovered the world's largest coral — measuring longer than a blue whale — on an expedition in Solomon Islands.

The "mega" coral is 112-feet wide, 105-feet long and 18-feet high, making it larger than a blue whale, the world's largest animal.

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.

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

The National Geographic Society’s Pristine Seas expedition has discovered the largest known coral in the world, spanning a circumference of 600 feet, larger than five tennis courts.

The mega-coral measures 34 metres by 32 metres – making it larger than a blue whale – and it is thought to be three centuries old
