Arthropods have long been the subject of close attention of mankind. Periods of worship gave way to eras of thoughtless destruction. Perhaps, at all times, the Arachnid class remained a real mystery to people.

Step 1
Some believe that spiders bring good luck and prosperity, but scientists warn that among these animals there are individuals with truly deadly venom.
Step 2
Dangerous European
Small (up to 1 cm in diameter), with a yellow belly, Sak spiders live mainly in Europe. Their feature is the construction of characteristic shelters in the form of bags, in which spiders lay supplies or hide if necessary. The bite of the yellow Sak spiders leads to severe pain with the likelihood of limb necrosis.
Step 3
Asian tarantulas
In this part of the world, spiders of the Theraphosidae family, in other words, tarantulas, are widespread. Having chosen for habitation the southeastern regions of Asia with rich flora and fauna, spiders have mastered various natural niches and adapted to a varied menu. Adult tarantulas reach impressive sizes - up to 20 cm in the span of shaggy legs. Fortunately, the bite of these spiders does not lead to tragic consequences, but it can cause fever, muscle cramps, and delirium.
Step 4
African sandpiper
In the southern regions of Africa, in the desert expanses, the six-eyed sand spider lives. Thanks to the skillful disguise of the spider, a meeting with him becomes an unexpected and unpleasant event. Being a hemolytic and neurotoxicant, the venom of this animal causes severe damage to the nervous system and blood vessels, which leads to prolonged bleeding, sometimes fatal.
Step 5
Deadly inhabitants of the Green Continent
Australian spiders, like other representatives of the mainland fauna, are unusual and very attractive. Missoulina and Sydney atrax, which are no more than 5 cm in diameter, can interest an inexperienced naturalist. However, curiosity can be fatal: if you do not take the victim to the hospital, death can occur several hours after the bite.
Step 6
Horror of america
The American continents are famous for their predatory fauna. Many dangerous spiders live here: the familiar black widow, the brown recluse spider, the Chilean recluse spider. However, arachnologists would agree that the most deadly venom is the Brazilian running spider, or wandering spider. Individuals of this species do not weave nets and constantly move from place to place in search of prey. Their glands contain the neurotoxin PhTx3, which, when ingested, causes paralysis of the respiratory muscles, which inevitably leads to painful death.
