Within the Great Barrier Reef there are several habitats. Consistent throughout the entire 1,616 mile formation are coral reefs. What we consider a piece of coral is actually a collection of a several individual coral polyps. Each coral is actually a number of polyps. Coral polyps are living creatures that encase themselves in hard, protective shells made of calcium carbonate. These shells band together forming colonies. The colonies together are known as reefs. Within the Great Barrier Reef there are millions of coral featuring a multitude of colors and textures. There are more than 400 species of hard and soft corals living in the Reef.

Housed within the reefs is a vastly diverse collection of animal life, many of which are endangered. Within its waters, the Great Barrier Reef provides homes to 5,000 species of mollusks and 125 species of sharks, stingrays and skates. In addition, there are more than 1,500 species of fish including the colorful clown fish. Thirty species of whales, dolphins and porpoises live in the Great Barrier Reef including humpback whales which use its warm, shallow waters as breeding grounds before journeying to Hawaii to give birth. Six endangered species of marine turtles also use the area to reproduce. The loggerhead turtle, one of the most highly protected endangered species, lives and breeds in the Great Barrier Reef. Over the last 40 years, the number of these turtles has decreased so rapidly that there are only 3% the number of creatures alive today. Housed around this extremely diverse collection of animal life are 2,195 species of plants. Above water 215 species of birds live on the Great Barrier Reef.

History of Lawn Bowling

The sport known today as lawn bowling began in England in the 13^th century. While lawn bowling has become very popular in England, it was not always so. In the 1200s people in England began playing a game based on the Italian sport “Bocce” which had been brought to the country by Julius Ceasar’s followers. They used stones or iron balls to play this game and called it “lawn bowling”. Lawn bowling immediately caught on in England, and by the 14^th century, it was extremely popular. In the 1300s the King of England, Edward III, banned lawn bowling. Because it was so popular, men stopped practicing archery (shooting a bow and arrow) and started playing lawn bowling. The king was worried that men would not be able to shoot a bow and arrow anymore because they were spending their free time lawn bowling. While this may not seem like a big deal to us today, archery was extremely important back then because it was an important skill for a man to have in war. After Edward III, Richard II, the new King of England continued the ban on lawn bowling. Players in Scotland, although technically under the rule of the King of England, ignored the ban and continued to practice lawn bowling. In order to encourage English citizens to stop lawn bowling, the government fined people sums of money if they were found playing the sport in public. The sport eventually came across the Atlantic Ocean to North America. Though some Americans took up the sport, it became more popular in Canada than the United States.
