Coral needs sunlight and warm, clean water to grow. Octocoral live in colonies. Different species of coral fight one another for space on a reef. There are lots of other animals that take shelter in coral reefs. Below is an octocoral crab. He uses coloration to camouflage (hide) amongst the octocoral colony.

 

Although many coral species look like plants, they are animals, opening and closing their polyps to catch plankton floating by in the ocean current. They are voracious predators that stun their prey with poisons. animals, opening and closing their polyps to catch plankton floating by in the ocean current.
