Which Spiders Are Dangerous to Humans?
WouterAlmost all spiders are venomous, but only a few of them are toxic enough to cause severe harm to humans. These are the medically important species, and the venom they produce can be life threatening.
The most dangerous spiders to humans are those that have neurotoxic venom. The venom from these spiders can overload the nervous system, causing death. In rare cases, the bite can also cause severe illness in humans.
The six-eyed sand spider is a highly poisonous arachnid that is related to the deadly recluse spider. It is found in the deserts of southern Africa. The venom it produces is very toxic and can kill a rabbit in five hours.
The Brazilian wandering spider is another dangerous spider to humans. The bite can produce intense symptoms including convulsions, sweating, vertigo, and pain.
Some people have a phobia of spiders. This fear is based on the myth that they are aggressive predators. In reality, they are predators that aren’t particularly aggressive. They only bite when they feel threatened. They are usually too small to penetrate human skin. They rely on webs to entrap their prey.
The Australian funnel-web spider is one of the most dangerous spiders in the world. It is a spider that grows up to 5 centimeters wide and is black. It is named for its funnel-shaped webs.
Fringed oriental tarantulas are another dangerous spider to humans. They can bite and leave painful skin lesions. Their venom is not harmful, though.
