Corals are made up of groups of tiny animals called polyps (PAH-lips). Most polyps are smaller than a pea. Thousands of polyps can live on a piece of coral. Where Do Corals Live? Coral reefs need certain living conditions to stay healthy. 1 They need healthy algae(藻类)for food. ...
1.Any of numerous small, sedentary animals that often form massive colonies in shallow sea water. They secrete a cup-shaped skeleton of calcium carbonate, which they can retreat into when in danger. Corals are cnidarians and have stinging tentacles radiating around their mouth opening. The tentacl...

Many people think rock-life forms in the sea filled with colourful fish when corals(珊瑚)are mentioned.But corals are made up of thousands of small organisms (1) which/thatlive and feed like any other sea life. Researchers in Hawaii and Australia have been engineering corals inside a lab ...
Coral reefs are like underwater cities made up of tiny animals called corals. They are in symbiosis with tiny plants called algae (海藻). The algae make food for the corals using sunlight. This is called photosynthesis (光合作用). In return, corals produce carbon dioxide and waste, which ca...
However, the results are dependent on the exposure scenarios and experimental conditions used, and it is noticeable that although a great deal of data have been collected (see, Falkenberg and Styan, 2014), there is little information in the public literature about the conditions that can occur ...
