Do eels crawl on the ground?

Eels are fish, but still some of the freshwater eels crawl out onto the ground! Like all other fish, eels have a backbone, they live in water and breathe with gills. Most types of eels live in the seas. Some species spend most of their lives in fresh waters, but they also live in the sea for some time. All eels spawn in salt water. It is in order to be able to do this that they have to crawl out onto land.

Freshwater eels often have to travel long distances to spawn. To reach the salt water, some of them have to travel part of the way on land, avoiding dikes or dams or other obstacles on their way to the sea. While they are on land, the mucus on their body helps them breathe through their skin and prevents destructive drying. You are unlikely to see eels on land as they make these transitions at night. But you can find them in barrels and ponds that are away from running water.

The eels that you will see away from the rivers are female. Male eels are smaller than females, usually no more than 0,3-0,5 meters in length. They can be found closer to the sea, in slightly brackish water. The females join the males and they head towards the sea together. By this time, they should work up fat and gain strength, because the path to the place where they themselves were born is a long one. In autumn, they leave coastal waters and travel hundreds of miles until they reach the calm and deep waters southeast of Bermuda. This place is known as the Sargasso Sea. Here they spawn and die.

It is also interesting that freshwater eels from Europe also come here to spawn. They swim across the ocean to spawn here! When fry emerge from the eggs, the Gulf Stream will carry them to the east. After two and a half to three years, the fry reach the mouths of European rivers, where they turn into young eels, and their bodies become similar to those of adults.

What are the most common surnames?

Over 80 million Chinese have the surname Chan. This is the most common surname in the world. In the West, the most common surname is Smith (English) or Schmidt (German). In the USA, for example, there are about 2,5 million "Smiths" (something like the Russian surname Kuznetsov).

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 ... >>

Jennie to demonstrate wireless near video over IEEE802.15.4 29.08.2008

Jennie Ltd. continues to use the IEEE802.15.4 open radio standard, demonstrating "near video" wireless transmission.

The first public demonstration will take place at the Wireless Exhibition at the Big Sight International Exhibition Center in Tokyo. The demo will show the transmission of video from the camera to the screen at a rate of several frames per second over an IEEE802.15.4 wireless link. The low power consumption of this standard makes this technology particularly suitable for applications that require long battery life in combination with intermittent video transmission.

Commercial applications of this technology include wireless peephole cameras, security cameras, home monitoring products, games, and advanced remote control solutions. The technology uses a commercially available image encoding chip together with Jennie's JN5139 single-chip wireless microcontroller, resulting in low cost and low power consumption.

Jennie Japan Office Regional Manager Toshi Sato commented, "IEEE802.15.4 is a global standard that coexists with other IEEE radio standards that are widely used around the world, but unlike other standards, IEEE802.15.4 has a flexible scope, allowing developers to use wireless connections in a wide range of new products.

Other radio standards are mainly designed for specific applications such as access points or wireless headsets, where the standard defines all functionality. This is not very convenient for non-standard applications, which, along with low power consumption, is an advantage of the 1EEE802.15.4 standard.
