Most stony corals feed at night, extending their polyps and using their nematocysts to sting passing plankton or small fish, which they pass to their mouth. They have associated algae which gives them color and nutrients while removing waste products that could damage the coral. Because of their size, zooplankton make up the larger portion of coral polyps’ organic diet. The group includes a variety of small protozoan life forms, as well as small copepods, amphipods and ciliates, ensuring quite a diverse diet. Different Ways to Approach Sun Coral Feeding The main reason why hobbyists are reluctant to get them is the fact they need to feed them every day. Coral polyps, the animals primarily responsible for building reefs, can take many forms: large reef building colonies, graceful flowing fans, and even small, solitary organisms.Thousands of species of corals have been discovered; some live in warm, shallow, tropical seas and others in the cold, dark depths of the ocean. The zooxanthellae receive nutrients and protection from the coral polyp and in return share the sugars it creates through photosynthesis. This is an example of a symbiotic relationship. How Do Corals Eat The Food? So, what do corals eat and how do they eat it? In addition to photosynthesis, most coral need to eat additional food directly from their environment. As we discussed above, one of the primary methods for feeding is to use their tentacles to immobilize and grab passing zooplankton and microscopic sea creatures. Do coral polyps eat the zooxanthellae? What do Sun Corals eat? Coral are living animals and they need to eat. Stony Coral Reproduction . This energy is transferred to the polyp, providing much needed nourishment. In the meantime the coral protects the algae from being eaten and gives it a fixed place to live. Most reef-building corals have a unique partnership with tiny algae called zooxanthellae. Types of Plankton Corals Eat. Coral reefs also have a special relationship with a living type of algae called zooxanthellae. Considering how important coral reefs are for the earth, mankind, and just about every living organism that resides on the earth, especially the 25% found inside the coral reefs, we’d say whatever it is they eat, is very important. No, the coral polyps do not eat the zooxanthellae. Zooplankton are the main types of plankton that coral polyps ingest. […] When a reef is distressed, this normal feeding activity, which involves biting off the polyp heads and crushing them for the algae within, becomes a detriment to the overall health of the reef. What Stony Corals Eat . Win the zooplankton touches the tentacle the coral transports it into the little hole that is the mouth. When the Carl has eaten all it needs from the zooplankton it will spit out the waste through the same hole. The prey is ingested, and any waste is expelled out the mouth. The corals use their tentacle-like arms to catch the zooplankton floating around in the ocean. The algae live within the coral polyps, using sunlight to make sugar for energy. Sun Corals will eat different types of foods such as brine shrimp, Mysis, including a small fish, as well. Coral is a marine organism that consists of numerous polyps. They are found in tropical oceans but can also be kept in saltwater aquariums. You said that the corals eat their bacteria do they really eat the bacteria or do they absorb what the bacteria excretes. While these colorful fish technically eat algae that would otherwise suffocate coral populations, they also eat coral polyps. Coral reefs are some of the most diverse ecosystems in the world.
