The Six-Eyed Sand Spider is a medium-sized spider with a body length of about 8 to 15 mm and a leg length of up to 50 mm, living in the desert of South Africa. The venom of the six-eyed sand spider, one of the deadliest in the world, has been confirmed in experiments with bites that rabbits can be fatal in 5 to 12 hours. Toxicological studies have shown that its venom has a powerful role in hemolysis, can cause extremely serious harm to humans, and when the venom enters the blood circulation system, it will cause blood vessels to rupture and lead to organ failure. There is no antitoxin available until 2018, so the consequence of stinging will be amputation or death.
<h1>4. Black Widow Spider</h1>
The Black Widow Spider, also known as the Red Spot Spider, is often referred to as the Black Widow. In general, being bitten by a black widow is not fatal, but its toxin is more threatening to children and the infirm. Despite mild bites, their toxicity directly affects the central nervous system and muscle tissue. A victim of a Black Widow bite will immediately experience acute, severe pain because the toxin directly stimulates your "hypersensitive" central nervous system and brings some other unpleasant side effects. It is 10 times more toxic than the rattlesnake. Severe pain, nausea and mild paralysis of the diaphragm after being bitten, but recovery without serious complications. Its poisonous juice is more poisonous than that of the rattlesnake, but the amount of secretion is small, making its fatality rate slightly lower.
<h1>5. Brown spider</h1>
The brown spider, also translated as brown recluse spider, violin-backed spider, belongs to the family Sicariidae, a well-known venomous spider that lives in southern North America. The body length is between 6-20 mm, but it is also possible to grow larger. Toxic, bites can quickly develop erythema, ulceration, nausea, children's reactions after being bitten are particularly intense, in 2014 a 5-year-old American boy died within a day of being bitten.
<h1>6. Rat spider</h1>
There are eleven subspecies known to rat spiders, ten of which live in Australia. Only one, called M. tussulena, was found in Chile. The damage caused by the bite from this rat spider attack is no less severe than that of the Sydney Funnel Web Spider. Several rat spiders living in Australia have been found to have severe symptoms similar to those produced by a cobwebbed spider after a bite, but not severe symptoms of poisoning. Most medical records describing the clinical manifestations of a rat spider attack mention that antivenom was not used and that no severe symptoms were present. Unlike the Sydney funnel web spider, the rat spider is not aggressive to humans and does not even use venom when attacking.
<h1>7. Red-backed spider</h1>
The red-backed spider, also known as the red-backed spider, is a red-backed widow spider that is mainly native to Australia. The red-backed spider is a highly venomous spider, between 2-8 mm long, with obvious red stripes on the back, extremely aggressive, and the wound begins to heat and pain after being bitten for five minutes, and if there is no serum treatment, it will die within a few hours. But since 1955, there has been only one recorded death from a red-backed spider bite in April 2016.
<h1>8. Indian gorgeous rainforest spider</h1>
Arboreal spiders, the temperament is very fierce, generally knotted webs inhabit the tree hole, agile movements, strong aggression, often in the absence of warning to bite people, their toxicity is also stronger than the general hair spider, so it is not suitable for touching or playing. There have been severe consequences of the bite of its breeders, severe pain that lasted for several days, and convulsions in the bitten arm, which is speculated to have some neurotoxin.
<h1>9. Respect the tamarind spider</h1>
Jingzhao tamarind spider is a bird-catching spider unique to underground burrowing in China, a new species discovered by Zhao Jingzhao of Hubei University in recent years. Its morphology is very similar to that of The Hainan Bird Catcher Spider and the Tiger Pattern Bird Catcher Spider, and the individual is smaller than the Hainan Bird Catcher Spider, with a yellowish-brown body and no tiger stripes on the back of the abdomen. It is 55 to 61 mm long. The spider is fierce and poisonous. In recent years, there have been domestic scientists studying this species of venom pharmaceutical projects, and it is possible that this species has been raised on a large scale in Guangxi for the extraction of toxins.
<h1>10. Yellow sac spider</h1>
Yellow sac spiders are minimally venomous, but even so, they are still more toxic. Fortunately, however, they rarely approach humans and bite. One of the dangers of their bites is closely linked to methicillin-resistant Staphylococcus aureus infection, which is so severe that it can lead to osteonerene or tissue necrosis, but the extent of their toxicity remains controversial.
