Soft corals are found in oceans from the equator to the north and south poles, generally in caves or ledges. The more acidic seawater makes it more difficult for corals to build their calcium carbonate skeletons. This energy is transferred to the polyp, providing much needed nourishment. Some species, however, such as the Christmas tree worms, actually bore into the skeleton of the coral, damaging it in search of food and protection.

What do rainforests and coral reefs have in common? Hard corals that form reefs are called hermatypic corals. If a portion of a larger colony is broken off from the main colony during a storm or boat grounding, the separated individuals can start new coral colonies that are genetically identical to the parent colony. Soft corals also live in colonies, that often resemble brightly coloured plants or trees, and are easy to tell apart from hard corals as their polyps have tentacles that occur in numerals of 8, and have a distinctive feathery appearance.
