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 solid, long-lasting structures. Their solidity is due to the fact that they are formed by the hard parts of the animal skeletons. Their longevity is due to their ability to resist shocks even after the death of organisms (cf. the high-rising primaeval reefs). The interstices are sealed and soldered by sediments and coral secretions.
