Hi guys, today we are going to see the chapter The
Blue Whale In this chapter, we are given details of blue whale. Its
weight is over 1,30,000 kg. It can be 33 meters long. Its tongue is
three meters thick. Some of its arteries are so big that children can
swim in it. Though it has a huge body, it can swim at a great speed of
30 kms per hour. It can eat upto 4000 kilos of food in a day. A baby
blue whale is about 8 meters long and its weight is around 10000 kg.

A whale can eat upto 4100
kilos of food a day. But it has no teeth. It
swallows a huge quantity of water. Then it
throws it out through a sieve of bones in the
upper jaw. The sieve is called a “baleen”.
Some whales have teeth, too. They eat fish
and other sea creatures. They even eat
small whales.

A blue whale has a tail like a
fish, therefore some people think that it is a
fish. But it is not. The blue whale breathes
air. It can stay under water for an hour. Then
it comes to the surface to breathe. When it
breathes out, it blows out water. From
distance, this looks like a fountain. Secondly,
the whale is a warm-blooded creature but
the fish has cold blood. The blue whale has
a thick layer of fat under its skin. Therefore,
even in ice-cold water it can live. Thirdly the
fish lays eggs, but the whale gives birth to
young ones. Therefore, we call it a mammal.
At the time of birth, the young one is about
8 metres long and it weighs around 10000
kg.

The whale is an interesting
creature. We do not know many things
about it. Yes, we know one thing very well.
Their number is decreasing very fast. Soon
there may be no whales. Men hunt and kill
them because all the parts of a whale are
useful. All the nations should come together
to protect such a wonderful sea creature.

Read this poem aloud
I wonder why the grass is green,
And why the wind is never seen.
Who taught the birds to build a nest,
And told the trees to take a rest?
And , when the moon is not quite round,
Where can the missing bit be found?
Who lights the stars, when they blow out,
And makes the lightning flash about?
Who paints the rainbow in the sky,
And hangs the fluffy clouds so high?
Why is it now, do you suppose,
That Dad won’t tell me, if he knows?
