Two Christmas Tree Worms (Spirobranchus giganteus) are attached to an underwater coral reef.  Also known as Spiral Gilled Tube worm.  These are living organisms that filter plankton from the water to feed on, as seen here.  They are highly sensitive to water movement and recoil entirely if the pressure changes around them.  Their resemblance to the festive trees give them their name.  Here we see two worms emerging to feed.  Image taken whilst scuba diving at Ko Haa, Krabi Province, Thailand.  Sony mirrorless camera, with underwater housing used.
