One of the night dives was done with different torches that output blue/UV light. This caused the corals and other organisms to fluoresce.
This is used to check the health of the reef as living coral fluoresces.
A shark kept following us around and getting in the way, which was annoying because he did not fluoresce.
The reef took on a completely different look.
Most of the corals fluoresce green.
There were some reds but it was harder for the camera to pick it up.
The greens were very bright.
It was a bit tricky to light.
The sea squirts didn’t fluoresce but the other corals do.
It looked really cool seeing the reef in a completely different light.
We didn’t move around much and just found a spot and got as close as we could to really check out the reef.
This let us see some really cool things.
Like these tiny organisms that were called coral fleas.
They looked really neat walking all over the coral. Never would have noticed them without the different lights which lit them right up.
