Transcript of Animal Adaptations
The size of the Great Victoria Desert is 424 400 square kilometers.
It is the 3rd largest desert in the world after The Sahara and Arabian desert.
The Great Victoria Desert was the first desert in Australia crossed by a European explorer named Ernest Giles in 1875 and it was named after Queen Victoria.
The Great Barrier Reef is the largest reef system in the world.
It composes to over 2900 individual reefs.
The Great Barrier Reef
The clownfish are the size of a regular teacup.
The average life span is 6-10 years.
The clownfish has a bright orange colour with white stripes.
The clownfish lives in an anemone barrier surrounding them safley.
The common clownfish has normally got 3 white stripes on its body while other varieties can have more or less stripes for camouflage. Their stripes are coloured so they can warn predators to stay away.
A lifesaving adaptation that the clownfish has is that it is able to live amongst the predatory, stinging tentacles of the sea anenome. The oily skin of the clownfish gives it the advantage of hiding amongst the anemone which is poisonous to all other marine life.
Spikes on their back protect them from predators. It also help's them get a lot of water when it is drought.
Thorny devils can change colour when distresed to fit into its surroundings.
It was named by some pioneers who thought it reminded them of Joshua from the old testament bible, who was waving them onto a promised land.
The Joshua Tree has a lifespan of 200 years and is a member of the lily family.
The Joshua Tree grows 3.048cm flowers and when their fruit falls it drops many little flat seeds.
The fruit of Joshua Tree are 5.08cm to 6.35cm wide and is a browny green colour and matures in late spring.
Thank you for listening and watching our presentation and I hope you have learnt something about the Great Barrier Reef, the clownfish, the anemone, the Great Victoria Desert, thorny devil and the Joshua tree.

Anemone diagram/ adaptation
The poisonous, stingy tentacles of the sea anemone spend most of there time attached to rocks and waiting for fish to pass and get ensnared
in their venom-filled tentacles.
The tentacles are triggered by the slightest touch shooting a venomous filament into the victim while sending paralyzing neurotoxin into the helpless prey.
There are more than a thousand
different species of anemone
spread across the worlds ocean
at varies depths.
This is a fake head, so when the thorny devil feels threatened it hides its real head and fools other animals thinking the fake head is real.
The thorny devil has channels in its body which lead to the mouth of the animal, this allows water to travel through these channels while the thorny devil repeatedly opens and closes its mouth and water drips in.
The Joshua tree has a very thick trunk to keep water in, which in the dessert is very crucial.
They have roots near to the surface and spread out far to make good use of any rainfall, but this leaves the trees prone to strong winds
The plant has thick fleshy leaves which help them to store water.
