Whale :-environment's friend

Whales are the largest animals in the sea. We know that the largest animals on land are elephants . But compare to a whale,an elephant is a tiny creature. Whales are huge and heavy giants. The largest whale, the blue whale, grows about a hundred feet long, some of them weigh more than a hundred and twenty tones, while the normal weight of an elephant is not than seven tons. A whale eats two or three tones of food at a single meal.

  If whale eat so many tones of food at each meal. The blue whales live wholly on plankton. Plankton is spread over miles and miles of sea water.

  Smaller that the blue whale in size is the sperm whale. It grows to a length of about sixty feet. Inside the huge skull there are large space filled with a clear oil called " SPERMACETI", which is used in candles and cosmetics. It is from this 'SPERMACETI' that "sperm" whales get their name.

These giants of the sea eat not tiny plankton, but gigantic squids, which are themselves nearly thirty feet long. When these squids stretch their arms out, they are almost fifty feet long. The sperm whales are powerful drivers. They dive fifteen hundred feet deep in the sea and fight fierce battles with giant squid.

   But whales can not breathe under water. This is because water may get into their lungs and drown them.When these animals want to breathe., they come up to the surface of water,draw in a breath of air and go down again.

  Their lungs as well as stomach are as large as the rooms in our houses. In fact , a man can walk about inside a whale stomach.

  Whales are hunted because men can get various valuable product out of their bodies.

Under a whale's skin there is a kind of fat called "BLUBBER". This layer of BLUBBER is six to twelve inch thick, and it keeps the whale warm in the cold ocean water.And from this BLUBBER we get whale oil. Whale oil is used in making soap, margarine (artificial butter) and several other things.Whale bone and whale meat also bring large profit to the hunter. 

AMBERGRIS:- From the whale's stomach we get something called "AMBERGRIS" . AMBERGRIS is very valuable. It is used in manufacturing expensive perfumes.
