My favorite dive so far this year was a night dive with glow worms in Providenciales Turks & Caicos. A few days after each full moon (and about 50 minutes after sunset) glow worms rise up from the sand to mate. I was at the back of our group and taking pictures. After taking some pics of a huge crab, I looked up towards the group, before I grabbed my dive light, and the darkness had turned into a universe of stars. I have seen the “sparks” from bioluminescence on night dives before, but with the glow worms the ocean was full of tiny yellow/green lights - absolutely beautiful!
