Section 1, Geography and Make up of
Great Barrier Reef
 You will learn about what
the Great Barrier Reef is
made from and the different
types of coral that create
the reef.
 You will also learn about the
geography of the reef, such
as where it is located and
where certain types of coral
are located within the reef.

Geography and Make up of Great Barrier
Reef
 The Great Barrier Reef is off the coast of Australia,
near Queensland
 The Great Barrier Reef is made of:
 2,900 individual coral reefs
 900 islands
 All living organisms
 And it stretches over 1,600 miles

Geography and Make up of Great Barrier
Reef
 World’s largest single structure made by living
organisms.
 Composed of billions of tiny organisms called coral
polyps.
 Creates a habitat for many animal species.

Geography and Make up of Great Barrier
Reef
 Ribbon and deltaic corals form in the north part of the
reef, but are not found in any other part of the reef.
 Fringing Corals distributed widely but most common
towards the southern part.
 Crescentic Corals are most common shape of reef in the
middle of the Great Barrier Reef.
Back
Next
Geography and Make up of Great Barrier
Reef
 Planar corals found in
northern and southern
parts of the reef.
 Most islands on Great
Barrier Reef are found
on planar corals.
 Reefs attached to
mainland are rare.

Application
 Think about how the Great Barrier Reef provides more
for the environment than habitats for animals. What
are some other things the Great Barrier Reef does for
the environment?
 Once you have done this, you can move on to the next
section.

Section 2, Life In and Around the Great
Barrier Reef
 The Great Barrier Reef supports a diversity of life,
including many endangered species.
 It provides habitats for:
 Ocean Animals
 Coral Species
 Land Animals
Section 1
Next
Ocean Animals
 Six different species of sea turtles
 Thirty species of whales
 Great Barrier Reef is the mating
ground for Humpback whales
 Dolphins, Porpoises
 125 species of sharks and stingrays
 5000 species of mollusks
 Nine species of seahorses
 1500 different species of fish
Back
Next
Coral Species
 400 different species of
coral, such as:
 Brain Coral
 Fire Coral
 Staghorn Coral
 Both hard and soft forms
of coral
 The individual coral reefs
make up the entire Great
Barrier Reef.
Back

Land Animals
 Some of the coral is above water and has created islands for land animals to
live.
 Some of the species are:




Seven different species of frogs
215 species of birds
17 species of snakes
Over 2195 plant species
Back

Application
 Think about how the Great Barrier Reef creates
habitats for land animals as well as ocean animals. Do
you think it would be difficult for these species of
animals to find new places to live if the Great Barrier
Reef did not exist?
 Once you have done this, you can move to the next
section.

Section 3, The Environment and the
Great Barrier Reef
 The Great Barrier Reef was used by
the Aboriginal people and it was
important to their culture.
 Besides the Aboriginal people, the
Great Barrier Reef was not studied
until the 19th century
 After studying and exploring the
reef, they found:
 Places with guano deposits
 Convenient locations to construct
lighthouses
Section 2

Climate Change
 Ocean warming causes
coral bleaching
 Expected to become
annual occurrence
 When temperatures rise,
some fish species seek new
habitats
 Effects sea turtle
population around the reef
Back
Next
Pollution
 Declining water quality
 Poor water quality due to increased light and oxygen
competition from algae
 Northeast Australian rivers pollute reef during
tropical flood events
 90% of pollution comes from farm runoffs
Back

Crown of Thorns Starfish
 Prey on coral polyps (which
makes up the Great Barrier Reef)
 Large outbreaks of these starfish
can devastate the reef, such as in
2000 when an outbreak of crown
of thorn starfish caused a loss of
66% of live coral
 Causes of outbreaks of these
starfish are:
 they occur in a natural cycle
 Poor water quality increases the
risk of outbreaks
 Overfishing of starfish’s
predators
Back
Next
Fishing
 Overfishing of keystone species, such as Giant Triton,
can disrupt food chains vital to reef life
 Fishing causes increased water pollution from boats and
catching unwanted species
 Fishing causes habitat destruction from anchors and
nets
Back
Next
Application
 Think about what
other types of effects
pollution has on the
Great Barrier Reef and
the world in general.
 Once you have done
this, you can move on
to the practice before
the quiz.
