Corals are animals, what we know as a coral, is in fact a group of small animals called polyps that need food to survive. Corals are benthic organisms because they live at the bottom of the sea. The subclass of benthic organisms that corals belong is called Macrobenthos, for being large enough to be seen at the naked eye. Corals live mostly in tropical waters, because they do not tolerate waters with a temperature below 18 Celsius.
