floor.• They are the builders of the reef!• A single coral animal is called a
coral polyp. • The coral polyps live together in
colonies.

What do they eat?
• To get energy to build the coral reef the corals need to eat.
• The polyps use their tentacles to catch tiny animals that float in the water called zooplankton.
• But corals get MOST of their food from marine plants that actually live inside the coral!

What do they eat?
• A microscopic type of algae called zooxanthellae actually live inside corals, just under their skin.
• Corals are solar-powered just like trees on land. The algae that live inside the coral soak up the sun all day - just like sunbathers on the beach.
