Spiders are a source of fear for many other creatures, including humans, not only due to their appearance with multiple legs and hairy bodies but also because of their deadly venom. There are many types of venomous spiders; below are some of the most venomous and terrifying spiders in the world.
Spiders belong to a group of predatory, invertebrate animals classified as arachnids; their bodies consist of two parts, eight legs, non-chewing mouths, and no wings – sharing the arachnid class with scorpions, ticks, etc. There are numerous species of spiders, some of which are non-venomous, while others are highly toxic.
Brown Recluse Spider can cause blood infection upon biting and can resist most types of antibiotics. A bite from this species can lead to necrosis. This spider can be found throughout the United States, usually hiding in leaves or grass. Fortunately, this spider rarely approaches humans to attack.
Goliath Birdeater resides in Southern Europe and tropical forests, scientifically named Lycosa tarantula. Victims of this spider will fall into a coma after being bitten. We know very little about the venom of the Tarantula.
Chinese Bird Spider is a large black spider with a leg span of up to 20cm. Scientists have conducted extensive studies on this venomous spider because of its aggressive behavior, capable of taking down a mammal with just a small amount of venom.
Mouse Spider primarily lives in Australia. This spider often bites humans but does not inject venom. It can be lethal if timely treatment is not administered.
Brown Spider and its relatives are highly venomous species. They often hide, so the number of their victims is not high. A bite from this spider can cause necrosis, with the necrotic area potentially reaching up to 25cm in diameter. The venom can lead to kidney failure, resulting in death.
Redback Spider primarily lives in Australia. Before an antidote was discovered, this spider had caused the deaths of 14 individuals.
Black Widow Spider is not only venomous but also exhibits cannibalistic behavior towards its mate. The venom of the Black Widow is 15 times more potent than that of a rattlesnake. Its bite causes muscle spasms and can even lead to paralysis. However, before an antidote was found, 5% of its victims died.
Sydney Funnel-Web Spider is one of the most venomous spiders in the world, scientifically known as Atrax Robustus. They have large fangs and inject venom when they bite. Their venom can kill almost all primate species, including humans.
Six-Eyed Sand Spider is also a reclusive species with little contact with humans and is considered quite “gentle.” Its venom causes necrosis and localized clotting, leading to death.
The Brazilian Wandering Spider has been recognized in the Guinness World Records as the most venomous spider in the world. This spider is highly aggressive and will bite whenever possible. Its venom contains neurotoxins that affect the respiratory system, causing suffocation and ultimately death. The venom can also lead to impotence in men.
Wolf Spider. The wolf spider primarily lives in terrestrial environments such as plains, mountains, deserts, and plateaus. Although it is venomous, it only attacks humans when it perceives danger and needs to defend itself.
Noble False Widow Spider. Despite its regal appearance, it has no compassion whatsoever. It is one of the most frightening spiders on Earth found in England. Its bite causes pain, swelling, and nausea. If infected, the wound can lead to necrosis! This is one of the most venomous spiders currently living on Earth.
