What is the biggest whale?

The largest whale is also the largest animal in the world. This is a blue whale - its length can exceed 30 meters, and its weight reaches 125 tons. It can be found in any seas, but most often it comes across in the Pacific Ocean. It belongs to the group of toothless whales (another group is called toothed whales). It is rather difficult to imagine that the largest animal in the world is able to do without teeth.

How do they do it? In their mouth they have a device consisting of hundreds of horny plates called baleen. They grow in the palate (upper part of the mouth) and form a kind of sieve. The whale feeds as follows: with its mouth wide open, it quickly swims through the accumulation of prey, which consists mainly of small mollusks, shrimps and fish. Closing his mouth, he forcefully pushes water out of it. Water is filtered through the whalebone, and the prey remains.

The mouth of a whale resembles a huge container. And the length of his head is about a third of the length of the body.

Among toothed whales, sperm whales are the largest. They have a huge head and reach 20 meters in length. The killer whale, or whale killer (actually a large dolphin), is the only representative of cetaceans that feeds on other warm-blooded animals. The length of the killer whale is about 9 meters, and it easily overtakes the seals. Flocks of killer whales attack even large whales.

Due to the fact that whales live in the water and have a fish-like body, we often compare them to fish. But the structure of the skeleton, the circulatory system and the brain, they are not at all like fish.

Random interesting fact from the Great Encyclopedia:

Who made the first needle?

A needle is a very small tool, pointed at one end, with a hole in the other, which serves to thread a thread through it. Man invented the needle so long ago that we can't even tell when it was invented.

We know that the first needles were made of bone, ivory, bronze or horn. Some of them were more like an awl used by shoemakers, since they did not have a hole. They were used to make holes in various materials. Well-finished needles made of fish and bird bones have been found among the objects of the Stone Age. For thousands of years, eyed bone needles were used by more advanced peoples.

Even needles made of stone have been found in the ancient Egyptian ruins. The Romans were familiar with bronze and iron needles. Many well-made needles have been found during the excavations of Pompeii. Steel needles, similar to modern ones, were first made, it is believed, by the Chinese. They were brought to Europe by the Moors in the Middle Ages. The first steel needles in Europe were made in the German city of Nuremberg in the XNUMXth century.

During the reign of Queen Elizabeth I, the German Elias Grose taught the English how to make steel needles. It is now an important industry in England, which, along with France, is the main producer of needles. Although the manufacture of sewing needles is well mechanized, their manufacture is still a complex procedure. In total, during the manufacturing process, the needle passes through the hands of more than 20 people!

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The colonization of Mars is not far off 17.06.2012

Perhaps the first landing on another planet will be the biggest and most exciting reality show in the history of television. In any case, this is what the authors of the concept hope for. Enthusiasts of the original idea - Nobel laureate, physicist Gerard Hooft and the creator of the famous reality show "Big Brother" Paul Romer.

They are one of the founders of the Mars One company, which is preparing a mission to Mars, which is planned to be turned into a TV show. As part of this mission, by 2033 it is planned to create the first human colony of 20 people on Mars. During the seven months of the flight, the first crew of the Martian mission will be watched by millions of TV viewers on Earth, thereby funding the continuation of the colonization of the Red Planet.

The initiators of this unusual idea want to take advantage of the opportunities of private companies, such as SpaceX, to deliver the first colonists to Mars in 2023, and their return to Earth is not planned. The first crew members will prepare the Martian "home" and conduct a series of scientific studies. Their Martian life will be broadcast on TV, which will raise money to send a new batch of colonists. By 2033, the population of the Martian "village" will grow to 20 people.

Such a scheme for organizing and financing such an ambitious mission was never seriously considered. However, progress in the field of private astronautics makes this venture quite feasible, albeit incredibly difficult, given the scheduled timeline. Many space experts believe that the "crazy bunch of TV people" are not able to cope with such a mission and will only kill people.

However, given that the colonists are not faced with the task of returning to Earth, and the drama of emergency situations will even raise the rating (and hence the profit) of the space reality show, then the task of Mars One does not look so difficult and may well find support from investors.
