00:00A word of warning, when you're in Australia, never stick your finger into these holes.
00:05It might be home to burrowing spiders.
00:08Some species have a bite powerful enough to pierce nails.
00:12It feels similar to a hammer on your finger because of the venom.
00:15So always give your boots and outdoor clothes a quick check to be safe.
00:20Animals sometimes make homes or look for food in them, especially bandicoots.
00:25Silk-lined burrows and shady spots might belong to funnel-web spiders.
00:30The silk works as a trip line to alert the spider inside about what's happening outside.
00:35Look for shiny dark brown to black spiders with finger-like spinnerets at the end of
00:40their abdomen.
00:41Then, you'll find them.
00:43Males have a hefty mating spur sticking out of the middle of their second pair of legs.
00:48When these spiders feel threatened, they make aggressive moves, rearing up and showing off
00:52their startling fangs.
00:54These spiders, which belong to the Erinita order, are known for their funnel-shaped webs
00:59that widen at the entrance.
01:01They patiently wait in the narrow funnel for prey to touch the web, then swiftly capture
01:06it.
01:07In Australia, large brown spiders frighten people due to their venomous bites.
01:11They are infamous for causing people to lose their lives in southern and eastern Australia,
01:17particularly in the Sydney area since the 1920s.
01:21Quick access to the antidote after a bite is crucial in preventing severe consequences.
01:28The next spider is one of the world's most dangerous venomous spiders.
01:31Phonutria nigrivitur is a spider living in South America.
01:36People often call it the Brazilian wandering spider.
01:38You see, in Brazil, 4,000 people get bitten by this critter each year.
01:43The bites can cause serious issues, such as hypertension, blurred vision, sweating, and
01:48vomiting.
01:49You wouldn't want to meet with this creature as you can also face way more severe consequences
01:53than blurred vision.
01:55In some situations, its kiss can take a life.
01:59Apart from messing with humans, this spider has a diverse menu, including crickets, katydids,
02:05and even larger options like tree frogs, lizards, and bats.
02:09Operating under the cover of darkness, these creatures are the most active during the night.
02:14They ambush their prey instead of relying on webs.
02:17In the daytime, they seek refuge beneath logs or in narrow crevices.
02:22They love to be around banana trees, but can be found in urban areas and inside homes too.
02:28If you spot them one day, be prepared.
02:31This creature's body is covered with thick brown hair and is not that small.
02:36In 2013, a London family had to leave their home due to an infestation of Brazilian wandering
02:43spiders.
02:44Trouble began when an egg sac, hidden in a bunch of bananas, made its way to their local
02:49grocery store.
02:50No one noticed.
02:51When the family bought the bananas, the egg sac broke open.
02:55Potentially lethal spiders spread around the house.
02:59Over 2,500 people visit poison control centers annually in the US.
03:04Black widows are spiders with the signature hourglass mark on their bellies.
03:08Well, let's talk about their bite.
03:11These creatures have a bad reputation because their venom is supposedly 15 times stronger
03:16than what rattlesnakes pack.
03:18When they bite humans, the bite causes muscle aches and nausea.
03:22The venom can even mess with breathing by paralyzing the diaphragm.
03:26Despite these cases, most people who get bitten don't end up with serious issues unless
03:31they're elderly or very young.
03:34These sneaky creatures don't pick just one spot to hang out.
03:38You can find them in woodpiles, burrows, or among plants that act as scaffolding for their
03:43webs.
03:44Black widows are especially dangerous for other insects and their mates.
03:48After a not-so-romantic mating dance, ladies sometimes go all Hannibal Lecter on their
03:53mates.
03:55These spiders are architects too, spinning massive webs where females stash a cocoon
04:00loaded with hundreds of eggs.
04:02Baby spiders move out once they hatch, but the web stays put.
04:06Those webs are also traps.
04:08Different kinds of prey later join the black widow's spooky snack collection.
04:15Yellow sac spiders range in size from approximately 0.12 to 0.6 inches and construct silken tubes
04:22under stones, in leaves, or in grass.
04:26They're found across the United States and southward toward Mexico and South America.
04:30They are venomous to humans and, unfortunately, are commonly spotted indoors.
04:36The venom of the yellow sac spider contains cytotoxin.
04:39This is a substance that can damage or impair cell function.
04:43Reactions like redness and swelling at the bite site are common.
04:47Yellow sac spiders are not known for their calm nature either.
04:50For instance, a female yellow sac spider may bite when protecting her eggs.
04:55These spiders usually come in different light colors.
04:58They can be a hassle for people in more than one way.
05:01Your car can be in danger too.
05:03On rare occasions, they may even set up nests in car engines.
05:10Moving on to wolf spiders.
05:12They're part of a large and widespread group found worldwide.
05:15They're named this way for their wolf-like hunting behavior of chasing and pouncing on
05:19prey.
05:21Around 125 species exist in North America, and approximately 50 live in Europe.
05:27These spiders are typically dark brown, with long, broad, hairy bodies and sturdy elongated
05:33legs.
05:34Like me.
05:35Just kidding.
05:36They're super speedy.
05:37While they usually create silk-lined, tubular nests in the ground, some may conceal the
05:41entrance with debris.
05:44Others build turret-like structures.
05:46A few species also spin webs.
05:48Wolf spiders may bite in self-defense.
05:51They are venomous, but their bites are not considered dangerous.
05:55Some people who are allergic to spider bites may experience nausea, dizziness, and an elevated
06:00heart rate.
06:01The bite of the spider's large fangs is similar to a bee sting, so it can cause a physical
06:06wound at the bite site, and the venom may cause itchiness.
06:10The combination of their powerful bite, rapid movements, and startling appearance can be
06:15quite unsettling.
06:19Beware of the red-backed spider, a close relative of the notorious black widow.
06:24It used to live in Australia, yet it has managed to spread its web across New Zealand, Belgium,
06:29and Japan through grape exports.
06:32The distinctive red stripes or hourglass marks on their black backs are more noticeable in
06:37females.
06:38Disturb a female, and you'll see how she can defend her eggs – you're likely to
06:43get bitten.
06:44These spiders can sneak into shoes or clothing, lurking against the victim's skin while
06:49they're dressing.
06:50Both male and female red-backs have a venomous bite.
06:54Their venom is a cocktail of neurotoxins.
06:57It can cause sweating, rapid heartbeat, and swollen lymph nodes.
07:01The red-back has control over the venom dose, so symptoms vary based on how much is injected.
07:08Australia deals with over 250 red-back bites annually, many requiring anti-venom treatment.
07:14The latest case, when a person lost their life after being bitten, dates back to 1956.
07:20Yet it can happen, so stay vigilant and cautious around these stealthy spiders.
07:27Let's talk about the heavyweight champion of the spider world, the Therophosus blondi,
07:31casually known as the Goliath bird-eater.
07:35This giant tarantula can stretch up to 11 inches and tip the scales at 6 ounces.
07:40To put it in perspective, this spider is big enough to cover your dinner plate and is certified
07:45by the Guinness World Records.
07:47The nickname might make you picture a tarantula feasting on a hummingbird, but that's more
07:52of an artistic exaggeration dating back to the 18th century.
07:56These spiders are more into munching on arthropods and rarely go for bird snacks.
08:01Goliath bird-eaters don't bother with webs like their spider buddies.
08:05Instead, they're all about silk, using it to line their cozy burrows beneath the forest
08:10floor.
08:11The spider itself looks dangerous, but its bite almost never requires a doctor's visit.
08:17It feels more like a wasp sting.
08:19Goliath bird-eaters are the biggest spidey on Earth.
08:22On the other side of the spectrum, we have this guy from Colombia.
08:26They are among the tiniest spider species.
08:29Grown-up males of this species are 0.015 inches long, tinier than your average pinhead.
08:36Females are usually a bit larger.
08:39Well, that was creepy, wasn't it?
