Small marine animals called polyps create coral reefs. Related to anemones and jellyfish. These can live individually (like many mushroom corals do) or in large colonies that comprise an entire reef structure. The polyp uses calcium and carbonate ions from seawater to build itself a hard, cup-shaped skeleton made of calcium carbonate (limestone). This limestone skeleton protects the soft, delicate body of the polyp. Coral polyps are usually nocturnal, meaning that they stay inside their skeletons.

Their skeletons are white, like human bones. Generally, their brilliant colour comes from the zooxanthellae (tiny algae) living inside their tissues. Humans have skeletons within while polyps like beetles chose to reverse the order.

A polyp has a sac-like body and an opening, or mouth, encircled by stinging tentacles called nematocysts. At night, polyps extend their tentacles to feed.

Most coral polyps have clear bodies. Several million zooxanthellae live and produce pigments in just one square inch of coral. These pigments are visible through the clear body of the polyp and are what gives coral its beautiful color.   Drawing calcium from the sea the polyps produce reef even as our architecture would indicate: there is nothing that we have brought special which isn’t part of nature.
What makes us then differentiate one another? (Ack:coral.org)
