An invertebrate called a coral polyp can range in size from the size of a pinhead to as much as one foot in diameter. Corals prefer the warmer waters of the tropics since they cannot survive in water that is below 18 degrees Celsius.
Nonetheless, since they do not produce their own food like plants do, corals are considered to be animals.
