Summative assessment for the unte-Making contact" and "Animal world
Task 1. Listening
Recently, someone asked me: 'Why are there so few blue animals?' I gave a few examples of blue
animals, but the truth is I was curious myself about the fuct that blue is quite rare in the animal
kingdom. So, today I'm going to talk to you about the colour blue in wildlife. A good place to start is
under the sea. To a scuba diver, most fish seem to be blue, swimming around in a blue world. That is
until they shine a dive light on them, and see the multitude of colours they have
For some animals, blue is used to warn off predators. Deep in the Amazon Jungle lives a small frog
which is a brilliant blue colour. It is called the blue position dart frog, and it is one of the most
poisonous frogs in the world. One look at the blue poison dart frog's colour, and any predator knows
that this little fellow is not to be messed with Some blue poison dart frogs produce enough poison to
kill twenty humans. An interesting fact is that they aren't born poisonous, but they become toxic from
their diet of particular insects. There is a reptile in Australia that uses blue in a similar way. When it is
threatened, it opens its mouth to reveal a bright blue tongue. When it comes to mammals, there are
very few examples. Perhaps the most famous is the blue whale. Now, the blue whale is the largest
animal that has ever existed on the planet but, although its name suggests otherwise, it is actually
greyish in colour rather than blue. Some breeds of cats are claimed to be blue but in actual fact they
are grey too. The reason why there are no blue land mammals is because land mammals are hairy
Land mammals have black, brown, yellow or reddish hair. Lastly, let's move on to insects and to one
of my favourite blue creatures. There is a butterfly which lives in Central and South America called
Menelaus Blue Morpho. It is a large butterfly with a wingspan of 15 cm, and although the female is
brown in colour, the male is an unforgettable shade of blue. Then, of course, there's the common blue
damselfly, which you've probably all seen near rivers and lakes all across the UK. There are 2.600
damselfly species and although they are frequently confused with dragonflies, there are many
differences between them.
