According to the American Psychiatric Association, one in ten people in the United States suffers from at least one type of phobia. Out of them, it is estimated that 40% of individuals have phobias related to bugs, snakes, and mice.
Arachnophobia is characterized by an irrational fear of spiders, but most people who are diagnosed with this condition don’t require any treatment. However, how many of us can say we like spiders?
Even if you are used to them or you gnash at the very thought of one of these creatures living in the same room with you, it would be best to know what spiders can be harmless and which ones are dangerous. Therefore, if you plan on traveling around the globe or just want to be more informed, here is a list of the top five most threatening spider species in the world.
Brazilian Wandering Spider
Out of over 40,000 known species of spiders, only a few are venomous and pose a threat to humans. The Brazilian Wandering spider is one of them and can be found in tropical South America and Central America.
They can grow up to six inches and can inject a neurotoxin that is 20 times deadlier than the venom of the famous Black Widow. A simple bite is known to cause convulsion, hypothermia, nausea, swelling, and sweating while the most severe cases can lead to paralysis and asphyxiation.
Sydney Funnel Web
If you don’t plan a trip around Australia with a four-wheeler you might steer clear of this spider. It is native to Eastern Australia and can usually be found within 62-mile radius of the Sydney area, hence its name. It enjoys the specific warm climate, and you can stumble across it on trees, tree stumps or under rocks.
And, despite its rather small dimensions, its bite is extremely dangerous to humans.
The male’s venom can cause severe pains, hypotension, vomiting, and respiratory problems. It is known to cause death within 15 minutes, and this is why if you happen to enjoy hiking or outdoor activities around the Sydney area, you need to stay protected using a pair of waterproof hiking shoes, and have an antidote with you at all times.
Six-Eyed Sand Spider
This spider only lives in the deserts and sandy areas of Africa. It is known for being able to survive for long periods of time without any food or water. Its bite releases a necrotoxic venom that destroys the tissues and thins the blood.
Severe cases of biting can lead to a rupture of the blood vessels, and the worse part is that there is no antidote for it. However, these spiders are known to be very shy and can rarely be encountered by people.
They belong to the family Lycosidae and, unfortunately, they are spread all over the world. The family includes over 125 species that live throughout North America and other 50 that live in Europe.
These spiders are small to medium-sized and have hairy bodies and long legs. The Wolf Spider is not considered aggressive, but it will bite for self-defense purposes. Its bite can cause several allergic reactions, including nausea, increased heart rate, dizziness or skin swelling.
This insect is part of the Latrodectus genus and the family Theridiidae. 31 recognized species in this family can be found all over the world, including in North America, Europe, and Australia. The iconic Black Widow is also known as the redback due to its striking red markings and the black abdomen.
Its biting used to be deadly before the discovery of an anti-venom, hence the bad reputation of the Black Widow. Some of the symptoms include nausea, swelling, sweating, and abdominal cramps.
