During the manta ray night dive the mantas come very close to divers because they are feeding on plankton attracted by lights. Divers hold flashlights and buckets of lights are placed in the center of the circle. Although the mantas might bump a diver, divers are asked not to touch mantas because they are coated in a thin mucous layer that protects them from parasites and bacteria that can be rubbed off.
