What snakes are venomous?

Man has always felt fear and aversion to snakes. Their appearance, the way they moved, and the fact that people died after being bitten by snakes, caused this horror.

There are over 2000 types of snakes. They live on the ground, in soil, in water and in trees. They can be found in almost all parts of the globe, with the exception of the polar regions and some islands.

What are the poisonous teeth of snakes? They are hollow, with a hole at the top. These teeth are located in the upper jaw and are connected to poison glands located inside the head. A venomous snake cannot be made completely harmless by removing its teeth, because they can grow back.

Snakes usually release their venom into their prey to kill or paralyze them until they are eaten.

There are about 120 non-venomous snakes that live in the United States. But there are only four poisonous varieties. One of them is a coral snake from the cobra family. She lives only in the south.

The other three species belong to the family of pockmarked vipers - these are the rattlesnake, the muzzle and the water muzzle. Rattlesnakes are about 10 species. All of them can be combined into one type, which is easily recognizable by the rings on the tail.

Northwest Asian vipers, like rattlesnakes, are called lateral attackers because they move sideways as well as in a normal direction. About 600 species of snakes are venomous, but only a quarter of them are fatal to humans. Vipers are the only poisonous snakes in Europe. Only three species live in Great Britain: the smooth snake, the common snake and the viper. And only the viper is poisonous. There are no snakes in Ireland, but English snakes live in fields, steppes and forests.

Random interesting fact from the Great Encyclopedia:

What knots do sailors use to measure speed?

A knot is an off-system unit of ship speed used in the maritime practice of many states (including Russia), equal to one nautical mile per hour (1,852 kilometers per hour, or 0,514 meters per second).

The term "knot" originated in the era of the sailing fleet, when the speed of the vessel was measured by a hand log, the log of which was divided into segments of 1/120 nautical mile (about 15,4 meters), indicated by tied knots. The lag sector was thrown over the side of the moving ship and, holding in place by the resistance of the water, pulled the laglin behind it from the ship. The number of laglin knots drawn from the lag view in 1/120 hour (0,5 minute) corresponds to the ship's speed in knots, that is, in miles per hour.

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 ... >>

Under the gaze of the machine 13.09.2008

A curious experience was conducted by English psychologists under the guidance of Melissa Bateson.

Having placed a vending machine with drinks in the laboratory, which worked no matter what coin was put into it, psychologists offered the participants in the experiments to throw a coin into the slot and get a glass of drink. At the same time, there was no one in the room except the subject.

The experiments lasted 10 weeks, and every week the experimenters changed the stickers that adorned the front wall of the machine. Sometimes these were photographs of flowers, then photographs of human eyes.

In the "flower" weeks, the vending machine's revenue was significantly lower. Especially a lot of money was thrown into the machine in the tenth week, when a picture of eyes with a very direct and "piercing" look was pasted on it.

It turns out that when they look at us, we become more generous, even if they look only from a photograph.
