At night the Cargo wreck glows. What looks like slightly boring, if colourful, stubs of coral during the daytime come alive at night. Known as Tubastrea coral, these are non-reef building coral which do not host photosynthetic algae within them like the coral we are most familiar with.
These are usually found in deeper waters and in areas where they are exposed to currents. The polyps extend tentacles into the water during the night and feed. The effect is quite startling with entire sections of the wreck appearing to wave to and fro, shimmering in the torchlight as the corals feed. It is an unforgettable experience night diving with these corals.
