The female intersubtitle spider body is about 1.14 cm long, while the male intersubtitle spider body is relatively small, only about 0.42 cm, less than half of the female intersubtitle spider. Perhaps because the male intersubtle spider is relatively small, after mating, the female intersubtle spider often eats the male intersubtle spider, so intersubtle spider is also called the "black widow".
Of course, the situation where female intersectomy spiders eat male intersectomy spiders may be a matter of probability, and not all intersectomy spiders eat their companions. Because scientists have conducted experiments to put male interstellar spiders and female interstellar spiders in a container to live, but they have not seen any female interstellar spiders hunting and killing male interstellar spiders. If there are multiple spiders living together, they may kill each other.
For us, it is not rare for the scepter to eat his spouse, because there are many such situations in the animal world. Many spiders will also eat male spiders after mating, and so will mantis. This phenomenon of eating a spouse is called "sexual food".
What makes people scary is that the venom of the genus gangster spider is extremely toxic, 10 times stronger than that of the rattlesnake, and the rattlesnake itself is a highly venomous snake, which shows how toxic the "Black Widow" is. The female black widow has a huge poison gland in her body, and when they bite each other, they release super-concentrated venom.
Their venom contains a protein neurotoxin. These toxins will act on the nerve synapses of vertebrates, making people feel the feeling of needle pricking, and symptoms such as fatigue and dizziness. In severe cases, shock and even death will occur. A technology website once listed the most poisonous animals in the world, among which the Black Widow's Spotted Spider ranked 21st and is one of the highly poisonous spiders in the world.
Customs intercepted Black Widow
Although we usually see some spiders, it is still relatively rare to see the poisonous spiders like Black Widow. Because the black widow intersecting spider is mainly distributed in some countries and regions along the Mediterranean coast of Europe, although it also exists in China, it is basically only distributed in Xinjiang and Yunnan, and there are basically no intersecting spider in other areas. Therefore, we all may not know much about the genus Bagu Spider. However, there is now a news about the Madara spider that makes it appear in front of all of us.
The thing is that when Xiamen Customs supervised a batch of imported car containers, it found that there was a black live spider in these containers. After discovering the live spider, the staff began to disinfect the container and inspect the vehicles and containers very carefully. Finally, a live spider was caught in the corner of the container. This living spider is a bit special. Its body is black, but there are red spots on its abdomen. After identification, this spider is the "Black Widow" Spotted Spider.
Xiamen Customs stated that this spider is one of the most toxic spiders in the world, and its toxicity is more than 10 times stronger than that of the rattlesnake. Moreover, the reproduction ability of this poisonous spider is quite amazing. It only needs to be mated once in a lifetime to reproduce for a lifetime, and can lay up to 5,000 eggs in a lifetime. That is to say, without interference, a black widow "couple" can give birth to up to 5,000 larvae in her life, and these offspring will continue to reproduce when they grow up, which will soon spread in theory. When a large number of black widows appear, it may pose a threat to the lives and safety of the people around you.
Regarding why there is a problem with the venomous spider like Black Widow in the container, some friends may think that it may have been deliberately put in by someone, but it is not ruled out that the black widow may have run into the container by himself and then come to our China with the container. We have also seen the discovery of foreign insects, small animals or even snakes in containers.
