Assalamualaikum how are you all friends. Alhamdulillah I am fine. What is the largest animal in the world today? If the question is asked to the children, they will surely answer, elephant or giraffe. There is reason to say, because they did not see anything bigger than an elephant or a giraffe in front of their eyes. In fact, the largest animal is the blue whale. The English name for the blue whale is the Blue Whale. The blue whale has another name. Another is the scientific name. The scientific name for the blue whale is Balaenoptera musculus. The maximum length of this whale is 110 feet. The weight is 1 lakh 6 thousand kg. Shakib, you said elephant is the biggest animal in the world. But think about it, the blue whale weighs the equivalent of 25 elephants. The weight of a blue whale's pocket alone is equal to that of an elephant. An elephant usually weighs 3 to 4 thousand kg. Blue whale weighs 1 lakh 6 thousand kg. And the weight of the tongue is 3 to 4 thousand kg. However, there are small species of whales in the world. The maximum length of small whales is only 10-11 feet. They weigh 300-400 kg. The blue whale has a huge body structure but special features. The whale's front arm is enlarged and changed into a fin. They have no legs behind them. So can move fast. Their tails extend parallel. Not as steep as a fish. Their bodies are smooth, and there are no scales like fish. The skin is about 10 inches full (thick) fat. So they can withstand extreme cold in the deep waters of the sea. Their nostrils are on the head. The water drawn in the mouth through the nostrils is thrown upwards. The whale has no ears. Eyes on both sides of the head. In addition to infants, many people think whales are fish. Not really a whale.

In general, many of us know whales as fish. But not whales. Although there are many reasons behind calling whales fish. At one time many expert scientists thought whales were fish. Whales live in deep water and have tails. At that time science was not as modern as it is now. Aristotle, the first famous philosopher before BC, came up with the idea of ​​whales as mammals. In the middle of the eighteenth century, after much research and general consideration, scientists agreed that whales are not fish. It is the largest mammal in the world.

There are many species of whales. Therefore, depending on the species, there are two types of eating habits of whales. A species of whale eats prey with its teeth. These are small species of whales. Their food is fish, suede and other small marine animals. Another species of whale opens its mouth and draws water. These are blue whales. Then all the small animals or fish in the vicinity enter the mouth of the whale. Then the water goes out but the small animals get stuck inside as food. The whale can stay in deep water for up to two hours in a row as it can draw oxygen with plenty of air while breathing through its lungs. It is unknown at this time what he will do after leaving the post. However, scientists have found that blue whales live for 100 to 130 years.

Blue whales have many more characteristics. Blue whales are very friendly, social. They also have intelligence. Together, many whales roam, play, and swim. Respond to each other's calls. Whales have no ears. Even then they hear. These whales make a kind of special sound to communicate with each other. If a friend is in danger then go ahead to help together. Also, if a friend whale dies, they are very sorry. Although whales are not fish, people eat whale meat, fat and food in many countries of the world. Another reason behind not being on our food list is that at present whales are not seen in our Bay of Bengal. At one time people hunted a lot of whales. Because, worldwide whales were of commercial importance. As a result, the number of these whales has decreased a lot. That is why in 1987, the United Nations Whaling Commission banned whaling internationally. If you like my post, don't forget to like and comment. God bless you
