The Dhaka Times Desk Basically, we know the blue whale as the largest animal of all time in the world. Now the news is that the title of the biggest animal of all time may change. The giant 'Perusetus' whale is going to break the record!
Scientists believe that this blue whale is the largest animal that has ever appeared on earth. An adult blue whale weighs about 150 tons on average. They are about 100 feet in length.
But the title of the largest animal of all time seems to be changing. Because the record is going to be broken by his native giant 'Perucetus' whale. This whale is believed to be the largest and heaviest animal in the world. It is estimated that Perucetus weighed an average of 180 tons.
A new species of whale named Perucetus colossus, or 'giant whale from Peru', was published in July in the journal Nature.
It is believed that this whale lived during the Eocene epoch, about 38 to 40 million years ago. In terms of weight, they would no doubt outweigh the blue whale or any other animal, including the largest dinosaurs.
Paleontologist Giovanni Bianucci of the University of Pisa in Italy, the lead author of the study published in the journal Nature, said that the main characteristic of this animal is its weight. This suggests that, in fact, evolution can produce creatures that are beyond our imagination.
The partial skeleton of Perucetus was discovered more than a decade ago by Mario Urbina of the Natural History Museum of the University of San Marcos.
An international team has been excavating for years along a steep rocky slope in Peru's Ica Desert. This area of Peru was once underwater and is also known for its rich marine fossils. 13 vertebrae, 4 ribs and a hip bone were found in the spine of Perucetus whale. The bones are unusually large and extremely dense.
The researchers said that these dense bones indicate that the whale lived in shallow coastal waters. However, no part of the whale's teeth has been found, making it almost impossible to explain its lifestyle.
A 3D skeleton has been used to estimate the whale's size and weight by using modern marine mammals. From this it is assumed that the weight of the ancient animal was between 94 and 375 tons. But the largest blue whales weigh about 200 tons.

How to prevent dengue
Dengue is a mosquito-borne viral fever. This fever is different from other viral or bacterial fevers. However, this fever is not contagious in any way. This viral fever can occur alone or in combination with other viruses (chikungunya, yellow fever, Burma forest, flu, respiratory syncytial) and bacteria (pneumococcus).
Dengue fever is divided into two categories depending on the severity of symptoms and fever.
1. Common dengue fever
2. Dengue fever with bleeding.
In the case of common dengue fever, the following symptoms are mainly seen-
1. Sudden high fever lasting 2 to 7 days.
2. Severe headache.
3. Pain behind the eyes.
4. Along with the fever, red rash appears all over the body.
5. Severe pain in whole body as well as back pain.
6. Nausea or vomiting.
7. A rash or red bumps on the skin.
In case of dengue fever with bleeding:
1. Bleeding from nose, mouth or vomiting with high fever within 2 to 48 hours.
2. Fluid accumulation in chest or abdomen along with fever.
If any of these symptoms appear, seek medical attention immediately.
On the other hand
Wait at home for the first 3 days of fever. On the other hand, sponge the whole body with water every now and then. This will reduce the level of fever. Drink enough water and rest. After that, if the fever does not decrease or if it continues to increase after some time, consult a doctor immediately.
Things to do to prevent Dengue:
1. Try to keep the surroundings of the house as clean as possible.
2. If there are flower tubs or broken plastic bottles, can shells, tires or polythene inside the house, clean them quickly and drain the accumulated water from the flower tubs.
3. Spray or fog at least 3 times a week to kill mosquitoes.
4. You can keep mosquito repellent cream with you while going out.
5. After evening, younger and older members of the household should use mosquito nets.
6. Clean up any accumulated rain water, as this is the time when Aedes mosquitoes lay their eggs.
7. On the other hand, you can use mats along with mosquito nets to avoid mosquito infestation.
8. Since Aedes mosquitoes bite during the day, it is important to avoid sleeping with mosquito nets while sleeping during the day. Source: https://dmpnews.org
