There are numerous species of spiders in the world, and most of them are harmless to humans. However, among them, some spiders pose a real threat to our health. But what exactly will only have a beneficial effect on your health and good mood is Hellspin.
These small arthropod creatures have venomous bites and can cause serious harm. In this article, we will look at the most dangerous spiders in the world. We will find out how they have adapted to their habitats and how they attack their prey.
The Black Widow, one of the most famous spider species, is considered one of the most venomous creatures on Earth. The venom of black widow females is superior in toxicity to rattlesnake venom. However, only the bite of females poses a danger to humans, while the bites of males and juveniles are safe.
Like most spiders, the black widow hunts insects. Sometimes it can feed on mice, lizards, and even snakes caught in its web, but this happens extremely rarely. In desert areas, black widows even feed on scorpions. Their web is considered the strongest among other spider species. Instead of creating attractive nets, black widows weave dense and sticky weaves of thick threads.
Interestingly, studies have shown that the tensile strength of the black widow web is comparable to the strength of steel. However, considering that the density of steel is about six times higher than the density of the web. It turns out that the web of the black widow is stronger than steel wire of the same weight.
The Sydney funnel spider is an inhabitant with a radius of about 160 kilometers from the city of Sydney. Related species of this spider can be found in Eastern and Southern Australia, as well as in Tasmania. They mainly live south of the Hunter River in the Illawarra and west in the highlands of New South Wales. Sometimes they can be found near Canberra, located 250 kilometers from Sydney. These spiders often settle in gardens close to residential buildings, and sometimes penetrate the premises.
Sydney funnel spiders are real predators. Their diet consists of various insects, such as beetles, cockroaches, larvae, snails, and millipedes, as well as small vertebrates, including frogs. All the prey falls on the edges of the spider funnels, which they create from dry silk. Insects, attracted by the brilliance of the web, sit on it and find themselves stuck. A funnel spider hiding in a shelter moves along slippery threads to its prey and feeds on it.
Interestingly, representatives of primates, including humans and monkeys, are particularly sensitive to the venom of the Sydney funnel spider, while it is not fatal to rabbits, toads, or cats. The reasons for this feature are not fully known.
The Brazilian wandering spider, also known as the banana spider, is considered one of the most aggressive and dangerous spider-like creatures. Its venom is two to three times stronger than the venom of the black widow and the Sydney funnel spider.
The ingestion of the venom of this spider into the victim's body causes muscle cramps, tachycardia, a sharp increase in blood pressure, dizziness, vomiting, swelling, dehydration, and inflammation of the skin. Victims also often experience hallucinations, numbness of the limbs, and a burning sensation or crawling goosebumps all over the body.
Spiders do not always inject venom, so "dry bites" are not fatal. But they can contribute to the penetration of pathogenic bacteria into the blood. Banana spiders live in the north of Argentina, in the central and southern states of Brazil, as well as in Uruguay and Paraguay.
Often these spiders settle on banana plantations and penetrate residential premises, climbing into closets with clothes and shoes, as well as into bags with household waste. However, encounters with banana spiders in people's daily lives are still a rare occurrence.
