The Deadliest Spiders Quiz

Although bites from female black widow (Latrodectus mactans) spiders rarely result in death anymore if you're a healthy adult, bites will make you sick. Symptoms include nausea, profuse sweating, severe pain in the abdomen and back, muscle aches, hypertension and paralysis of the diaphragm (which can cause difficulty in breathing).

Although tarantulas can bite and inject venom into you, most bites are still considered pretty harmless, despite what movies would have us believe. Bites from a small number of the species may cause pain and suffering that lasts for weeks (sometimes months) or, rarely, an allergic reaction.

While black widow spiders have a bad rap for sexual cannibalism, it's not always on their menu. It's the dark fishing spider (Dolomedes tenebrosus) that has a taste for its own. (The desert spider Stegodyphus lineatus is known for eating its mother.)

True ... and false. There are two different insects that get easily confused — both are often called "daddy longlegs." The eight-legged insect that most of us think of when we hear the nickname isn't actually considered a spider, technically speaking. They're Opiliones arachnids named "harvestmen" and don't have venom glands (or fangs). There is, however, a pholcid spider with long legs that is venomous.

Wolf spiders don't spin webs to catch prey or to live in. These quick hunters live in burrows.

Female wolf spiders, which belong to the family Lycosidae, are the only spiders that care for their eggs and then for their spiderlings until the kids are ready to fend for themselves.

Yellow sac spiders caused Mazda to recall thousands of Mazda 6s manufactured between 2009 and 2012 to prevent fuel problems caused by arachnid infiltration.

Bites from yellow sac spiders are often mistaken for bites from brown recluse spiders. While symptoms are pretty similar, venom from the brown recluse spider is much more powerful.

The Thai zebra tarantula (Haplopelma albostriatum) is an aggressive and dangerous spider. Despite that, it's also known as the "edible spider," a delicacy found in Myanmar, Thailand and Cambodia.

The brown recluse spider is known as a "fiddler," "fiddleback" or "violin spider" because it has a dark, violin-shaped mark on its cephalothorax (head).

Sometimes called "banana spiders" because they're often found on banana leaves, a Brazilian wandering spider egg sac hitched a ride on a bunch of imported bananas and caused a potentially deadly infestation in a London home.

Unlike most spiders that have eight eyes in two rows of four, the brown recluse has six eyes with one pair in front and a pair on either side.

If bitten by a spider, don't attempt to remove venom from the wound. Seek professional medical attention — you may need antivenin to prevent damage and life-threatening symptoms.

Mouse spiders are often misidentified as funnel-web spiders.

Black widow spiders like to make homes and hang out in dark, protected places, inside and outside your house. They can be found in woodpiles, in crevices and dark corners and in infrequently used parts of the basement, crawl space or garage.

At the Australian water slide park named Jamberoo Action Park, you'll find the largest spider ... sculpture. It was created to accompany the park's Funnel Web water slide and modeled after a female Sydney funnel-web spider, but 420 times bigger.

The katipo spider is an endangered spider species native to New Zealand's coastal regions.

People aren't normally spider prey, but spiders will bite if they're startled or provoked.

In the time before antivenin, whiskey, cocaine and nitroglycerin were all used in treating black widow bites.

Among spiders, fewer than 20 (and maybe closer to a dozen) species are able to cause serious harm to a healthy adult human.

MRSA skin infections and some spider bites may look similar. Some bites may also resemble bites from fleas or bedbugs, as well as poison ivy rashes.

Some species of wolf spiders are opportunistic hunters who chase their prey (short distances). Others of the species are known to ambush.

There were 15 deaths related to Sydney funnel-web spider bites between 1927 and 1981.

Not only is one dangerous (the funnel-web) and one harmless (the funnel weaver) to humans, they also don't belong to the same species. Funnel weavers are part of the family Agelenidae, while Sydney funnel-web spiders are in the family Hexathelidae.

Spider bites are known for three related envenoming syndromes: funnel-web spider syndrome, caused by (you guessed it) funnel-web spider bites; latrodectism, caused by widow spider bites; and loxoscelism, caused by recluse spider bites.

The only spider known to be aggressive toward humans without being provoked is the funnel-web spider in Australia.

Venom from the Brazilian wandering spider is known to cause abnormally long erections in some men who have been bitten. Scientists isolated a protein called PnTx2, the ingredient in this spider's venom with potential therapeutic properties.

In the U.S., indoor plumbing helps reduce the number of spider bites, especially from black widow spiders, which were known to hide in outhouse toilets.

Without treatment, symptoms of an Australian funnel-web spider bite begin within 10 minutes and can kill a healthy adult within 24 hours.

And the award for most venomous spider in the world goes to the New South Wales native Sydney funnel-web spider, Atrax robustus. According to Guinness World Records, just 0.2 milligram/kilogram of the venom from the males of the species is considered a lethal dose. In comparison, the venom from the females of the species is known to be between four and six times less effective. Before antivenin was developed, bites were often fatal.
