Not all reefs begin naturally. For example, an ocean current may encounter a man-made
object, like a sunken ship. As a result, the water around the ship may become rich with
tiny animals called plankton. A lot of small fish gather there to feed on the plankton.
Consequently, larger animals are attracted to the ship. Because the ship has many little
openings, many creatures also have a place to hide. In time, the ship becomes covered
in polyps. As a result, it no longer looks like a ship at all.
