This is a tricky question and the topic also puzzled Charles Darwin when he visited the coral reef. The tropical waters where coral reefs are found are nutrient-poor. This is one of the reasons they are so clear. Darwin wondered how there was such an abundance of life with so few nutrients in the water.
The answer is the relationship between coral polyps and zooxanthellae. We will leave this one up to the imagination of your students, but it is just another example of the amazing diversity of life on this planet. These resources for ages are based on the journeys undertaken by science teams taking part in the XL Catlin Seaview Survey expeditions.
These resources present a complete scheme of work for the science classroom, covering core science and sustainability curriculum areas as well as enhancing students' creative and communications skills. Starting with the Great Barrier Reef in , these expeditions seek to create a baseline survey of the world's reefs as well as more in-depth research on the deep reef lying between 30m and m.

View all activities Coral feeding game. Activity steps Put on a glove. Mark the gloved back of the hand with green dots using stickers or a green marker pen. These dots represent the algae zooxanthellae within the coral polyp. Stick squares of double-sided sticky tape around each gloved finger.
Create a sleeve out of the paper bag or paper that fits your hand. Many corals will benefit from the food that you feed the fish and invertebrates in your tank. When meaty foods float by or land on corals, they will be consumed if the food is desired by the coral.
Copepods and Amphipods are quite easy to cultivate in refugiums. It is difficult to generalize the food requirements for groups LPS, SPS or soft of corals as there are always a few renegades in each group which have a more selective diet. We highly recommend obtaining a good book reference source on corals to determine what your specific corals feed on.
The sections devoted to each coral provide detailed information on what the corals feed on in the wild. There is also an excellent chapter devoted to feeding corals in your aquarium. Actively scan device characteristics for identification. Use precise geolocation data.

The coral polyp has these long and skinny tentacles armed with venom, which it uses to catch prey. Coral polyps usually only feed at night, and they so by extending their tentacles, stinging them, immobilizing them, and then they pull them into their mouths.
That being said, some really large coral polyps can eat small fish, but this is not often seen. This is usually considered to be their main source of food, but not the only one. Ok, so we already talked about how coral polyps actively hunt for passing zooplankton and other living microscopic sea creatures, but that is not the only way they feed or the only thing they eat.
Corals have a much more varied diet than you might think. So, what do corals eat and how do they eat it? It may seem like a challenge, but feeding coral is not very hard. If you have corals in your home aquarium, follow these tips to feed them properly. If they are really large corals with big polyps, you can try feeding them really small fish, chopped up fish parts, little chunks of shrimp, and other such things.
As long as corals eat it in the wild, you can feed it to them in your home aquarium. The smaller the corals are, the smaller the food needs to be. That way the corals can eat the small chunks and absorb the rest of their skin. Make sure to provide your coral reef with a lot of sunlight. Like we said before, algae that lives in coral needs to have a lot of sunlight, which in turn produces food for the coral.
So, having a lot of light will ensure the maximum production of food by the algae for the coral to eat. There are special coral nutrients and liquid coral foods that you can buy from specialty fish and pet stores. The high-quality ones come with all of the nutrients necessary to support the healthy growth of any coral reef.
Make sure that there is a medium current, decent waves and water movement, and water undulation in the tank.
