She continued to observe the spiders surrounding the tree where they were. The more she looked at Luo Yu, the more she frowned. She was wondering why this spider looked so familiar. It turned out to be a black widow.
Who in the 21st century has not heard the name of the black widow? This spider is not only very poisonous but also eats its mate after mating.
Its bite causes a condition called arachnidism, which causes severe muscle spasms and sometimes temporary spinal or cerebral paralysis, but rarely death.
All black widow species have a bright red hourglass pattern on their abdomen, and some also have other red markings on their bodies, which serve as a warning to those animals who see them.
Before the advent of antivenom, the mortality rate from these bites was 5%. Its median lethal dose was 0.002 mgkg, which means it didn't need much venom to kill its prey.
And now the spiders below, with the obvious red marks on their backs, are the best proof. This really opened Luo Yu's eyes.
Things that she didn't have the chance to see in modern times were seen in this backward ancient time. Is this considered good luck for her? Or bad luck for her.
Luo Yu, who was sighing, accidentally caught a glimpse of the dozen or so gray spiders, which were covered by the fallen leaves. They seemed to have merged into one body. If it weren't for the fact that he just saw the leaves moving, Luo Yu would have ignored them.
.
Luo Yu knows this kind of spider, and it is very impressive. The Brazilian Wandering Spider. Why Luo Yu knows this kind of spider is because it is included in the Guinness Book of Records.
The Brazilian Wandering Spider is included in the Guinness Book of World Records as the most venomous spider in the world, so Luo Yu is particularly impressed by this.
This spider is also aggressive, and its venom contains a potent neurotoxin that can cause breathing problems, followed by suffocation and death.
Another effect of its venom is priapism, which means an erection that lasts for a long time, ranging from hours to days. Its venom can also cause permanent impotence.
However, this venom is being studied for use in curing sexual dysfunction. It only requires the injection of 6 micrograms of venom to kill a 1-gram mouse, and the total weight of its venom reaches 1.069 milligrams.
Even after anti-venom was used for treatment, there have been incidents of human bites and deaths. Generally speaking, spider bites are non-venomous, and the pain from these wounds will not last more than 1 hour.
However, the pain of poisonous wounds will last up to 24 hours. The description in Wikipedia is this: "Spider venom can cause two consequences, either neurotoxicity (attacking the nervous system) or bone gangrene (attacking the tissues around the wound).
tissues and in some cases can attack vital organs and systems).”
It sounds scary, but there are enough scientific facts. Luo Yu still remembers that this kind of spider was said to be very evil at that time, and Jie Baina was known to everyone.
Moreover, these two kinds of spiders are very famous poisonous spiders in modern times. They are ranked first and second in the country. She really feels that she is lucky.
In fact, what Luo Yu didn't know was that many nobles in this dynasty hired people who raised such spiders to treat those who didn't.
