As it got dark the sharks started circling the boat. They were attracted by the fish, which were attracted by the plankton, which were attracted by the lights from the back of the boat.
So we decided to jump in the water for a dive.
The ocean was black except for our flashlights and the light from the boat.
The polyps all open up at night so the corals look bigger sometimes.
The eels are also out and about at night hunting. We tried looking hard for a octopus or cuttlefish but no luck.
