In nature, there are behaviors that humans cannot understand. For example, females will eat male animals after mating. Scientists named this behavior " sexual cannibalism".
Sexual diet, in layman's terms, it means that animals kill and eat male animals during or after mating,
Black Widow Spider-eating Similar diet
Speaking of similar cannibalism, I believe that mantis is the most impressed in most people's minds. In "Black Cat Sheriff", the female mantis will excrete anesthesia fluid on the "wedding night". The female mantis will anesthetize the male. At this time, the female mantis will bite the male's head in one bite, and the movements are quick and the mouth is never vague, leaving no affection for husband and wife, just like eating other foods. It feels like a dish arranged for him by God
In nature, there are far more female animals who eat the same kind of females than males. Especially among the arachnids and insects, it is even more common for females to eat males that masturbate with them. In addition to mantis, spiders, chiropins and a sea slug also have this special habit of eating males.
Black Widow
Today I want to talk about the black widow spider. Friends who like it remember to like it and support it. Let’s continue to talk about
is a large spider with a scientific name of the Spotted Corpse, belonging to the family Spider family and the Spotted Corpse. Its venom is violently toxic and is one of the world-famous venomous spiders. So, how poisonous is it?
How toxic is Black Widow? The real experience of the Guangdong uncle tells you
. In June this year, a real case happened in Guangdong. When Uncle He was farming in the fields, he was suddenly bitten by a thumb-sized black spider on his left wrist when he was suddenly caught by a black spider the size of a thumb on his left wrist
. Although he felt a little stingy at first, Uncle He didn't care. He thought it was just a bite by a spider, and it was no big deal. But as time went by, Uncle He felt something was wrong. Not only did his arms swollen and thicker, but his breathing also began to become rapid and his consciousness began to become blurred. He was sent to the hospital, after emergency treatment, he was out of danger of life
Uncle He's arm saved
A rattlesnake venom can kill at least 9 adults. After being bitten by a rattlesnake, he still faces the risk of amputation even if he receives timely treatment.
However, compared with rattlesnakes, the toxicity of Black Widow is actually stronger. According to National Geographic, the toxicity of Black Widow is about 15 times that of rattlesnake venom . Fortunately, the black widow spider does not release much venom, so it is generally rare to fatal
people will feel needle-punched in the wound, and the wound and nearby may be pale, red or urticaria. The severe pain will quickly spread to the abdomen, thighs, waist, etc. within about 5 minutes after being bitten. It can be seen how toxic this black widow, spider, is
The origin of the name of the black widow
The body of the black widow spider is black, and the male spider has red spots on the abdomen and a red hourglass-like spot. This spot is usually a red spot. Since the female of this spider bites the male spider to death immediately after mating, it is named "Black Widow" by the people
Black widow spider may be related to the size of the male spider
American researchers found that among wolf spiders, larger male spiders will never be eaten by their spiders, and 80% of smaller male spiders will be eaten by their spiders.
If the male spiders are smaller in size, they will easily be caught up and become prey and are preyed. Large female spiders eat their weak spouse because of two points.
The first point is because they are hungry. In order to replenish their physical strength, they have to eat the other party
The second point is because they have the ability to eat male spiders smaller than themselves.So those smaller than it will become food. This is the law of the jungle in nature
In addition to the black widow, there is also a kind of spider named Longxi. In the laboratory of the School of Life Sciences of Hubei University, two Longxi spiders were hanging on the spider silk, which was very sweet... But it was not long before sweet. In an instant, the male spider "ejected out" at a speed of 90cm per second, broke out from his wife's arms, and flew freely into the air. Finally, the food that became a female spider
Another type called strange spider is even more powerful. Before mating, the male spider directly tied the other party with spider silk. After mating is completed, the male spider can leave without any scruples, while the female spider has to spend a while to break free from the spider silk tied to the body. This is much safer
Nature can be said to be so big and all kinds of strange things. Look at the world rationally and live in harmony with nature.
