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.

Coral reefs are diverse underwater ecosystems held together by calcium carbonate structures secreted by corals. Coral reefs are built by colonies of tiny animals found in marine waters that contain few nutrients. Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups. The polyps belong to a group of animals known as Cnidaria, which also includes sea anemones and jellyfish.
