Black Widow may be the world's most famous venomous spider, but in general, being bitten by a Black Widow is not fatal. Black Widow's belly has a red hourglass pattern, which is its signature feature. The Black Widow spider has a black body, and the male spider has red spots on the abdomen and is between 2 and 8 cm in length. Because the female black widow spider will slowly eat its mate during the mating process, it is named black widow by the folks.

Black Widow

Black Widow is a spider with a strong neurotoxin . It is a widely distributed large widow spider that usually grows in urban settlements and rural areas. Its venom is more poisonous than that of the rattlesnake, but the lethality rate is slightly lower due to the lower secretion. The bite of a black widow spider often goes unnoticed, and the wound resembles a pinhole, so even if you are bitten, you may not notice it. In the beginning, you will usually only notice a slight swelling in the area of the wound and a dull, fuzzy imprint. However, after a few hours, the pain of the wound started to intensify, and the wound showed signs of hardening. Other bite symptoms include: chills, fever, vomiting, severe abdominal pain. Those with mild poisoning can be discharged after one or two days of treatment, while those with severe poisoning will spend a month in the hospital or even be life-threatening. Black widow spider venom promotes the release of the neurotransmitter acetylcholine. Acetylcholine acts on muscles, causing them to contract. In general, the toxins of black widow spiders pose a greater threat to children and the infirm. Both male and female, black widow spiders have a red hourglass pattern on their abdomens. Female spiders are generally larger, and contrary to folklore, female spiders rarely eat male spiders during mating.
