You wouldn’t expect a critter as tiny as a spider to instill as much fear as it does in something as comparatively huge as a human, but it most definitely does. Arachnophobia, the fear of spiders, is one of the most common specific phobias, affecting up to 6% of the global population.
Most people may fear these creepy crawlies for their large eyes, many legs, and the fact that they can be hiding almost everywhere. While there are about 45,000 species of spiders out in the world (and maybe a few under your roof), only about 30 of them are actually venomous.
Spiders are one of the most diverse and interesting groups of animals on Earth. While some species carry venom that poses a significant threat to humans, they’re not actively looking to harm you. Familiarizing yourself with the appearance of these dangerous spiders will help you safely discern the good from the bad when identifying them.
Here’s an exploration of some of the deadliest spiders from around the world.
The Black Widow Spider, infamous for its powerful venom, is primarily found in North America. Its venom is reputed to be 15 times more powerful than that of a rattlesnake. It is easily identifiable by its distinctive black body adorned with a red hourglass shape on its abdomen. A bite from this spider can lead to severe pain, muscle cramps, and even breathing difficulties.
Despite its fearsome reputation, fatalities from Black Widow bites are rare, thanks to advances in medical treatment. The venom can be particularly dangerous for children, the elderly, and individuals with weakened immune systems.
The Brown Widow Spider, a close relative of the Black Widow, is found in many parts of the world, including the southern United States, Africa, and Australia. It is lighter in color, tan-to-brown, and has an orange or yellow hourglass marking.
While the Brown Widow’s venom is less toxic than the Black Widow’s, its bite can still cause significant pain and discomfort.
Native to Australia, the Redback Spider is another dangerous member of the widow family. It is easily identified by its black body and prominent red stripe on its back. The female Redback is particularly famous for its venomous bite.
A bite from a Redback Spider can result in intense pain, sweating, nausea, and muscle weakness. General symptoms may comprise nausea, vomiting, restlessness, and elevated blood pressure. Respiratory failure might happen in some cases. Prompt administration of antivenom can prevent severe reactions.
The Brown Recluse Spider, also known as the “violin” spider due to the violin-shaped mark on its back, is native to the United States. It prefers dark, secluded areas like attics and basements.
This spider’s venom is necrotic, destroying tissues at the bite site and leading to serious wounds and secondary infections. Initial symptoms include mild pain and redness, but the condition can worsen over time.
Banana Spiders, including species like the Brazilian Wandering Spider, are found in Central and South America. These large, brown spiders are often discovered in banana shipments, hence their name.
The venom of Banana Spiders can cause intense pain, increased heart rate, and even respiratory issues. Their aggressive nature and potent venom make them one of the most dangerous spiders in the world. If you suspect a banana spider bit you, seek medical attention immediately.
Did you know that Funnel-Web Spiders have fangs strong enough to penetrate shoes? That’s not a very comforting thought. Native to Australia, they are among the most venomous spiders on the continent. They are characterized by their dark, glossy appearance and unique funnel-shaped webs.
Although funnel web spiders are venomous, they aren’t aggressive and bite only as a last resort if they feel threatened. Anti-venom was invented in the 1980s, and it has greatly reduced fatalities.
Yellow Sack Spiders are found all over the world, including in North America and Europe. These small, pale yellow spiders are often found in gardens and inside homes.
While not as deadly as some other spiders on this list, their bites can be painful and occasionally lead to secondary infections.
As if eight legs weren’t enough, here’s a spider with six eyes! Native to deserts in southern Africa, the Six-Eyed Sand Spider is a reclusive and highly venomous species. It is well-camouflaged, making it difficult to spot in its sandy habitat. It can go an entire year without food.
The venom of the Six-Eyed Sand Spider is highly necrotic and hemolytic, meaning it can destroy blood cells and tissue. Although bites to humans are rare, they can be extremely dangerous.
Mouse Spiders are found in Australia and are named after a now-debunked myth that they could dig a hole as deep as a mouse. Due to their similar size and shape, they are often mistaken for funnel web spiders.
While their venom is highly toxic, Mouse Spider bites are less common and usually less severe than those of Funnel Webs. Symptoms can include pain, swelling, and muscle spasms. Prompt medical attention is still recommended.
While most spiders build a web to attract prey, wolf spiders chase after them just as wolves hunt their prey. Wolf spiders are found in Europe and the Americas. These large, hairy spiders are often mistaken for tarantulas but are not closely related.
Wolf Spider bites can cause significant pain, itching, and swelling. While not usually life-threatening, their bites can be very uncomfortable.
White-tailed Spiders are native to Australia and are recognized by the distinctive white spot at the tip of their abdomen. These spiders are often found in homes, particularly during the warmer months when they are more active.
White-tailed Spiders do not spin webs. Instead, they are hunters that prey on other spiders. Their bite can result in a variety of symptoms, ranging from mild irritation to intense pain and swelling.
The Indian Ornamental Tree Spider, also known as the Poecilotheria regalis, is native to the forests of India and Sri Lanka. This striking tarantula is characterized by the vivid, ornate white, black, and gray patterns on its legs and body, making it one of the most visually stunning spiders in the world.
Despite its beauty, the bite of an Indian Ornamental Tree Spider can be quite painful. While not typically life-threatening, their bites may cause severe local pain, muscle cramps, and sometimes nausea or vomiting.
Love them or hate them, one thing is for sure; spiders are some of the most interesting creatures in the world. If you come across any type of spider, you’ll quickly reveal two personality types in humans. One being ‘turn-tail and run’, the other being ‘lean-in and study’.
