What do sharks eat?

There are about 250 different types of sharks, they vary in size: from 0,5 meters to 15-18 meters in length, such as the giant whale shark. Are there sharks that eat humans? Yes, 27 kinds of sharks can attack him. Among them are white shark, hammerhead fish, tiger shark, lemon shark. But none of the sharks attack humans as a means of food. Sharks eat mainly vertebrate fish, cephalopods, crustaceans such as lobsters and small shrimp. They also feed on turtles, dolphins and birds.

Some species of sharks feed on their relatives. The largest sharks, such as the whale shark, eat the smallest amount of food. They feed on small fish and tiny animals that live in seaweed. To find food, the shark relies mainly on its nose. The hungrier the shark, the more sensitive its nose. The shark circles around its prey for a long time before approaching it to strike. Sea foxes use long, curled tails to pierce their prey. They twist their tail from side to side, sometimes stunning the victim with powerful blows.

Often a school of sharks becomes so irritated that they eat everything and everyone in their path. The more they do it, the more furious they become. In this state, they can eat rubber tires, cans, boats, oars - anything that comes across. Scientists call this condition hungry rabies. Even the smallest and weakest sharks are dangerous during such a frenzy.

What is a guinea pig?

The guinea pig has nothing to do with the pig, it is related to hares and rabbits. In other words, the guinea pig is a real rodent and was bred by the ancient Incas in Peru, Ecuador and Colombia long before the arrival of the Spanish conquistadors in the New World. The Indians ate them and considered them a great delicacy. By the way, after the discovery of America, guinea pigs were exported to Europe for the same purpose.

Today, only a few tribes living in Peru eat guinea pigs. But all over the world guinea pigs are very popular as pets. Guinea pigs reach a length of 25 cm and weigh about 1 kg. They have no tail and small, round ears are hairless. Guinea pigs have four toes on their front paws, while only three on their back paws. All fingers end in wide claws.

Mostly guinea pigs live on plant foods. When eating, they usually sit on their hind legs. In the wild, guinea pigs live in burrows and feed at dusk or on cloudy days. When there is enough vegetation around, guinea pigs can go without water for a long time. In captivity, they can eat the same as domestic rabbits and rats, but in this case they need water.

Guinea pigs can have two or three litters a year, with two to three babies each. A few hours after birth, guinea pig cubs can run. Guinea pigs are very easy to care for and live up to 8 years at home. Pet stores usually stock a variety of guinea pigs in all sorts of colors and coat lengths.

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 ... >>

Belgium to build artificial energy island 08.03.2023

Belgium will create the world's first artificial island in the North Sea.

Elia presented a sketch of this project. She also said that the island will be named after the Belgian princess Elisabeth. It will be located 45 kilometers off the Belgian coast and will serve as a link between offshore wind farms and the onshore high voltage grid. The total capacity of wind turbines will be 3,5 GW.

Construction is scheduled to begin in early 2024 and be completed in 2026. The island is expected to be the first block of an integrated European maritime power grid that will connect various nodes and countries. For example, Belgium wants to build additional joint links with the UK and Denmark.

This will allow the country to access the vast amount of renewable energy needed to make its industry less dependent on fossil fuels in the short term.

In recent years, the concept of artificial energy islands has gained attention as a potential solution to meet the growing demand for clean energy. These islands can provide a reliable source of renewable energy and help reduce dependence on fossil fuels. In addition, they can serve as an energy storage and distribution center.

“We are proud to support this project through which we, as a Belgian consortium, can support our country in achieving climate goals. The combined experience of Jan De Nul and DEME as offshore specialists in dredging, rock armor and offshore energy is an absolute added value ," said Julie De Nul, director of the Jan De Nul Group.

According to the consortium, Princess Elizabeth Island will be the world's first man-made energy island that combines both direct and alternating current. The island's high-voltage infrastructure will connect wind farm export cables from the Princess Elizabeth Area, and also serve as a hub for future connections to Nautilus in the UK and TritonLink in Denmark.

In general, these facilities will facilitate the exchange of electricity between the countries, as well as being linked to the giant offshore wind farms in the North Sea, which will subsequently provide Belgium with large amounts of renewable energy.
