This still image of a small coral reef in the Bahamas containing a Brain coral and Great Star coral is one of 170 images taken over a period of one hour during twilight hours. It is during this time that many of the stony corals extend their coral polyps in order to begin feeding. Combining these 170 images into a time lapse video you can see for yourself as the Great Star coral feeds, constantly opening and closing its coral polyps, as well as watching the Brain coral’s polyps beginning to extend. Also note the number of hermit crabs moving throughout the video frame.
