Corals are beautiful when seen through your own eyes in sunlight, but for scientists at the University of Hawaii, seeing corals in this manner is not enough.
They are using a revolutionary new tool called a laser scanning confocal microscope to take photographs of corals that are one part art and one part science.
In this episode, they take us along for a ride with this amazing new technology and show us corals in a way we have never seen them before.
The microscope these scientists are using allows them to create stunning images of corals going about their business alive and unharmed.
No danger of decompression sickness on this one… the depths where these images were taken is measured in millimetres!
