Colorectal cancer. Although most will never develop into cancer, they do have the potential to become colon cancer. This cutaway diagram of a coral polyp shows where the photosynthetic algae, or zooxanthellae, liveinside the polyp's tissue. The temperature in the Indian Ocean was recorded 2C higher than the normal temperature in 1998. Changes in certain genes can cause cells to continue dividing even when new cells aren't needed. Coral species number in the thousands, and stony corals take on several characteristic forms. The polyps start their colonies from a firm base of hard rocks and grow upward until they reach the sea-level. Its often diagnosed with a colonoscopy, and stage depends on how far the cancer has.
