Poisonous spider spider

In a new study published in PLoS One, scientists say the poisonous spider spider (also known as the Black Widow spider) is moving further to North America because of its proper temperature. than.

The study also showed that in the last half century or so, this spider has been found more in North America and the habitat of this lethal poisonous spider has increased by about 45km.

One of the many effects is the gradual transformation of the territories of some species. Most animals have a certain temperature threshold that, when exceeded, cannot survive, but as the average temperature of the Earth continues to increase, these animals can be removed or Must have traveled to areas that used to be too hot or too cold.

To determine the true scope of this poisonous spider species, researchers have collected a lot of data from professional scientific observers and also from amateur scientists who are now able to The ability to contribute their discoveries to the scientific community thanks to the internet.

Currently, the team believes that this black spider distribution map is the most accurate, and it is slightly different from the previously defined range.

Climate change is a gradual transformation of the territories of some species.

The range of distribution in the North Pole of this spider now extends to the territories of Canada, the Midwest region in Wisconsin, the United States, where there has never been a spider's presence before.

This is, of course, not the first example that has shown us that artificial climate change makes species move into completely new areas.

Last year, scientists published a study that showed that the problem is not limited to animals, but also species that are also migrating due to rapid temperature changes.

The extremely dangerous Black Widow's venom

According to some scientific documents, Black Widow spider is considered the most horrible venom spider in the world. It is called 'black widow' because females often kill males right after 'salty concentration'. In this species, females are 2-3 times larger than males, so it is easy to finish off males after mating.

This spiders were most likely to live in South America or the Western Hemisphere.

The black widow's venom is extremely dangerous, 15 times stronger than a bell-tailed snake.The latrotoxin poisoning from their bite is a relatively strong neurotoxin, causing vomiting, shortness of breath, delirium, hemiplegia and convulsions.

If you are bitten by a Black Widow spider, you must immediately clean the wound with soap and water in the skin around the bite. If the bite is on the arm or leg, tie a bandage tightly above the bite and raise the limb to help slow or prevent the spread of the venom.

Make sure the bandages are not too tight that cut off the blood circulation in your arms or legs. After that, apply a cold compress to apply. Finally, you must go to the hospital immediately because the treatment of the bite of the black widow spider may require special treatment.

Although extremely dangerous to humans, the Black Widow spider bite rarely causes death if the wound is treated promptly. Only less than 1% of people with bites die. However, never be subjective when you accidentally meet this species.
