|Great Barrier Reef - Did You Know|
DID YOU KNOW?
600 continental islands and 350 coral
cays are spread throughout the reef.
There are approximately 3400 individual
reefs that make up the Barrier Reef.
That the Great Barrier Reef was declared
World Heritage on 26th October 1981.
The reef stretches for more than 2300
kilometres. From near Fraser Island off
the coast of Queensland Australia to the
Papua New Guinean coastline.
Not all coral is hard. In fact some are
soft and spongy.
The main industry on the reef is
tourism. Reported to generate more the 1
billion Australian dollars annually.
Sea Turtles do not have a sex when they
are laid; the heat of the sand that they
are laid in determines their sex. Sand
with a temperature of more than 27ºC
(80º F) produces more females. Cooler
sand produces more males!
The diversity of life in the reef is
immense with approx:
Majestic creatures, such as the giant humpback whales spend their winters in the tropics and may grow to more than 15 metres [45 feet] in length. Tourists revel in the dances that the whales perform right along side their boats. With huge tail flukes they make an impressive display. Another friendly marine mammal is the bottlenose dolphin who enjoy playing in schools. They often ride the bow waves of boats. Both the whales and dolphins are now a protected species.
