Brett Favre has only won Super Bowl XXXI (31) despite appearing in Super Bowl XXXII (32) as well. He was not the MVP of the game. Since Farve has only won one Super Bowl, he only has one Super Bowl Ring, the same number as his successor, Aaron Rodgers.
A coral reef is made of thin layers of calcium carbonate. Coral polyps form a living mat over a calcium carbonate skeleton. Stony corals (or scleractinians) are the corals primarily responsible for laying the foundations of, and building up, reef structures.Massive reef structures are formed when each individual stony coral organismâor polypâsecretes a skeleton of calcium carbonate.Most stony corals have very small polyps, averaging one to three millimeters (0.04 to 0.12 inches) in diameter, but entire colonies can grow very large and weigh several tons.assive reef structures are formed when each individual stony coral organismâor polypâsecretes a skeleton of calcium carbonate.

Corals extract calcium and carbonate from seawater to build an inner skeleton that is external to the coral. This external skeleton lies underneath a thin layer of tissue. Over the years millions of coral polyps in colonies create the framework of the coral reef. Coral reefs grow very slowly.
