This awesome time lapse video of coral is mind boggling.  Even though we see these behaviors in our tanks every day, we rarely get to see it in such detail and with the addition of the higher speed you can really start to understand what all of these bizarre physical forms and morphs are for.  The sponge movement is especially cool as the changes are very hard to perceive with the naked eye.  Enjoy the weekend eye candy.  Thanks for the tip, Laura and Caitlin!  More details on the movie HERE.
