found in warm and shallow waters and have high biodiversity despite being surrounded by relatively nutrient-poor oceanic water.<\/p> <p>The nutrients are located in the bodies of the organisms, living and dead.<\/p>\n<img src=\"http:\/\/naturejournals.org\/wp-content\/uploads\/2019\/07\/coral-animals-1-1024x609.jpg\" width=\"1024\" height=\"609\" title=\"6a3 Coral Reefs\" alt=\"6a3 Coral Reefs\">\n<p>Coral reefs are built upon the dead mineralized remains of coral remains.\u00a0 Live coral animals live on the surface, supporting a wide range of organisms.\u00a0 In a sense, coral animals are analogous to grasses in a grassland or trees in a forest.<\/p>\n[embed]https:\/\/vimeo.com\/472065837[\/embed]\n<p>This video shows the structures left behind when coral animals die.<\/p>\n<p>Coral reefs are often covered with colonies of different species of live coral animals.\u00a0 They catch plankton out of their water with tentacles.\u00a0 Corals are cnidarians and have stinging nematocysts on their tentacles that help them immobilize their prey.<\/p>\n<img src=\"http:\/\/naturejournals.org\/wp-content\/uploads\/2019\/11\/coral-anatomy-1024x782.jpg\" width=\"1024\" height=\"782\" title=\"6a3 Coral Reefs\" alt=\"6a3 Coral Reefs\">\n<p style=\"text-align: center;\">All of these videos show different types of coral animals.\u00a0 Each species has tentacles to grab prey and a mouth for feeding and eliminating waste.\u00a0 Some of the corals look a lot like anemone species.\u00a0 Some clown fish host either.<\/p>\n[embed]https:\/\/vimeo.com\/311595028[\/embed]\n[embed]https:\/\/vimeo.com\/314336018[\/embed]\n[embed]https:\/\/vimeo.com\/307156216[\/embed]\n[embed]https:\/\/vimeo.com\/307155037[\/embed]\n<p>Coral animals have microscopic protists called zooxanthellae living inside of them.<\/p> <p><strong>Zooxanthellae<\/strong> are dinoflagellates, a group of protists that are photosynthetic and can move through water with two whip-like structures called flagella.<\/p>\n<img src=\"http:\/\/naturejournals.org\/wp-content\/uploads\/2019\/07\/coral-zoo-1024x614.jpg\" width=\"1024\" height=\"614\"

Coral Reefs\" alt=\"6a3 Coral Reefs\">\n<p>The coral animal gets sugars from the zooxanthellae, and the smaller protists get nutrients from the coral and a place to live.\u00a0 What is the name for this win-win relationship?<\/p> <p>\u00a0<\/p> <pre>Answer: mutualism, or <br \/>mutualistic endosymbiosis<\/pre>\n<p>Changes in environmental conditions can reduce zooxanthellae in corals, leaving the coral animals pale and unhealthy.<\/p>\n<img src=\"http:\/\/naturejournals.org\/wp-content\/uploads\/2019\/07\/coral-bleach-1024x348.jpg\" width=\"1024\" height=\"348\" title=\"6a3 Coral Reefs\"

Reefs\">\n<p style=\"text-align: left;\">Dead or dying coral can become covered in algae, leaving it unlikely the colonies of coral animals will recover.<\/p> <p>\u00a0<\/p> <p style=\"text-align: left;\">Many factors impact the mutualistic coral-zooxanthellae relationship, including water temperature, pH, nutrients, and fishing practices (explosives, nets).<\/p>\n<p style=\"text-align:
