Have you ever wondered what exactly are these coral reefs made up of? The coral reefs are made up of as many as thousands of corals, and when this coral dies, it leaves behind the calcium carbonate skeleton. Further, the cycle starts again when the young ones attach themselves to the old skeleton. And so on, every generation builds up themselves on the prior generation. But what are corals? The coral reefs are made up of the actual animals called polyp (the physical part of the animal). This polyp is column shaped, and it attaches itself to the reef floor. Its top end extends into the water, being able to move freely. And like this, when thousands of polyp entwine, they form a colony, that is which forms a reef.
