00:00Let's get this thing started so it's clear to everyone.
00:03Venomous and poisonous are different.
00:05There are many lists and videos online titled and spam.
00:10Yep, top 10 most poisonous animals, but most of them just copy from each other
00:14and are actually mostly about venomous animals.
00:16A venomous animal is one that injects venom into its victim.
00:19A poisonous animal, on the other hand, is one that releases poison that can be inhaled,
00:24eaten, or touched by a predator.
00:26Now that the difference is clear, let's move on to the real introduction.
00:30The most common animals that people fear are those with extremely potent venom.
00:35In fact, the fear of spiders and snakes are two of the most common phobias in the world.
00:40But in reality, most of those species aren't actually dangerous.
00:44The only problem is, this video won't help lessen your fear.
00:47The animals on this list are arranged based on the subcutaneous lethal dose 50 or LD50.
00:53This means that as the rank increases, a smaller amount of venom is needed to kill a person.
00:59But before we start, if you're new to our channel, please don't forget to subscribe
01:04so you'll always be updated with videos like this.
01:09Number 15. Blurring Octopus
01:15The blurring octopus is small, about the size of a golf ball, but its bite has an LD50 of 0
01:20.3 to 0.36 mg per kilo.
01:24To understand, one mg is about as heavy as a dollar bill or a large grain of sugar.
01:29And here at number 15, we already have a venom that can kill with even less than that.
01:34In rats, about 25 midjigars is enough to kill an adult human male.
01:39But remember, only one blurring octopus has enough venom.
01:43Enough to kill almost 26 people.
01:46Sometimes you won't even feel the bite because it just feels like a small cut on the skin.
01:51You'll only notice it when symptoms start, like difficulty breathing, paralysis, heart failure, blindness,
01:57and death within 15 minutes if not treated immediately.
02:02There's no anti-venom for its bite.
02:04Your only hope is artificial respiration until the effects of the poison wear off.
02:09So if you're on the coast of Australia, avoid touching the beautiful blue ring of this tiny octopus.
02:17Number 14. Stonefish
02:22The stonefish has the most potent venom of all fish.
02:25It has an LD50 of 3 mg per kilo, of course, where else but Australia again, and the entire Indo
02:32-Pacific.
02:32The spines on its back contain venom that gets injected when stepped on.
02:36So if you're unlucky and you step on it with your full weight,
02:40you'll probably get a very high dose that could be fatal.
02:43The effects of the venom include intense pain, muscle damage, tissue necrosis, nerve damage, and even paralysis.
02:50Fortunately, there is anti-venom for the stonefish, but if left untreated, it can really kill you.
02:57Number 13. Dead Deathstalker Scorpion
03:03The dead Deathstalker scorpion is one of the oldest venomous animals on the planet,
03:08with ancestors dating back over 400 million years.
03:12So it's not surprising that this species has developed one of the most dangerous venoms in the world.
03:17It has an LD50 of 0.25 mg per kilo.
03:22This little monster has enough venom to kill a child or someone who is allergic to it,
03:27but it's rarely fatal to a healthy adult.
03:30However, its bite causes extreme pain.
03:33The Deathstalker can be found in North Africa and the Middle East,
03:36and it usually feeds on insects, which is perfect for its venom to kill quickly.
03:42There are even rumors that these creatures can glow in the dark to confuse predators,
03:46but this is not true.
03:48Scorpions only glow under UV light,
03:51and if they were to glow in the dark,
03:53it would actually be the worst defense for an animal that wants to hide in the darkness.
04:00Number 12. Mojave Rattlesnake
04:05The Mojave Rattlesnake produces both neurotoxin and hemotoxin,
04:10with an LD50 of 0.21 mg per kilogram.
04:14It can be found from the Mojave Desert to central Mexico,
04:18and based on LD50,
04:19it is one of the most toxic snakes in the Americas.
04:23They are most active from April to September,
04:25and sometimes accidentally encountered by people
04:28because they blend in well with their surroundings.
04:31The venom of the Mojave Rattlesnake
04:33causes severe pain, tissue damage, nerve death, and can be fatal.
04:38Fortunately, the Rattlesnake gives a warning to nearby animals to stay away,
04:42and there is also anti-venom available.
04:46However, despite this,
04:47there are still some deaths recorded each year because of these animals.
04:52Number 11. Assassin Caterpillar
04:57You wouldn't expect that a soft caterpillar or moth larvae would make it onto this list.
05:02It can be found from southern Brazil to Uruguay,
05:05and the hemotoxin it carries has an LD50 of 9 mg per kilogram,
05:10causing internal hemorrhaging around the bite area.
05:13If you're unlucky and you touch this green caterpillar, don't worry.
05:17A single caterpillar isn't enough to kill a healthy adult.
05:21However, they like to hang out in large groups on trees,
05:24so if you accidentally touch them,
05:26you could be seriously injured internally.
05:28An anti-venom has already been made for the caterpillar's venom,
05:31but that doesn't mean it won't hurt if you get bitten or stung by them.
05:3910. Sydney Funnel Web Spider
05:46For some reason, Australia is home to so many toxic creatures,
05:50and yet millions of people still live there.
05:52Only the male spiders of this species have a trap called tractotoxin,
05:56a venom with an LD50 of 0.16 to 0.25 mg per kilogram.
06:03The fangs of this spider are like long, hard rat teeth.
06:06They can pierce even a toenail if the bite lands just right.
06:10When the fangs penetrate, they attach so deeply to the skin
06:14that they need to be pulled or forced out.
06:17The venom of the funnel web spider attacks the respiratory system
06:20and can cause death within 15 minutes.
06:23Since 1981, there have been several bites.
06:26However, because of the availability of anti-venom,
06:29there have been no reported deaths from this spider.
06:369. Brazilian Wandering Spider
06:41If you've watched our video about dangerous toxins,
06:44you might know about the Brazilian wandering spider.
06:48Its venom, known as Furionegra bentoxin 3,
06:51has an LD50 of 0.134 mg per kilogram,
06:56making it the most dangerous spider in the world.
06:59If enough venom is injected into the body,
07:02it can cause paralysis and asphyxiation,
07:04which may lead to death.
07:06It also has a unique symptom called parietesum,
07:10which you can look up the meaning of if you want.
07:12G. A. Ondera called this the spider bone to the death
07:16because of its lethal capability.
07:18The Brazilian wandering spider got its name
07:20because it roams the forest at night
07:22before hiding in a place during the day.
07:25Sometimes this place is a banana grove
07:26beside a mountain or plantation,
07:28and it can end up in another country
07:30through, of course, export.
07:32A family buying fruit may not know one is there.
07:36There is anti-venom for it,
07:38but if you're in another country,
07:39it might be hard to get.
07:44Number 8. Maricopa Harvester Ant
07:50You might not expect that the most dangerous insect
07:53in the world is full of venom,
07:54and it turns out it's actually an ant.
07:57The Maricopa Harvester Ant,
07:58which is found almost exclusively in Arizona,
08:00has an LD50 of 0.12 mg per kilogram.
08:04The bite of this ant causes severe damage
08:07and pain that lasts for about four hours.
08:09However, since each of these ants
08:12weighs less than one mound shy,
08:14you would need more than 200 bites
08:16to kill an adult human.
08:17Unless you are allergic to the venom,
08:20the problem is that each bite contains an alkaloid
08:23that alerts other ants nearby,
08:25causing them to attack together.
08:27There's no anti-venom for the Maricopa Harvester ant,
08:30but there have been almost no reported deaths caused by them.
08:36Number 7. Black Tiger Snake
08:41Let's return to Australia's subtropical region.
08:44The venom of the Black Tiger Snake
08:46has an LD50 of 100 micrograms per kilogram,
08:49which is 2,000 times more dangerous than sodium cyanide.
08:54Usually, it quickly escapes from people,
08:56but when threatened,
08:57it can strike accurately
08:59and has enough venom to kill a dozen people.
09:02The mix of toxins from the Black Tiger Snake
09:04can kill within 30 minutes
09:06through blood clotting and paralysis.
09:08The anti-venom is a big help
09:10in reducing the number of deaths each year.
09:12However, for those who are not treated in time,
09:14the mortality rate is 40 to 60%,
09:17and there are still victims each year
09:19who do not reach the hospital immediately.
09:22Number 6. Many-banded crate
09:26In southern China, Vietnam, and Taiwan,
09:28you can find a very dangerous and cannibalistic snake,
09:31the many-banded crate.
09:34This species has its own unique characteristics.
09:36It has a special neurotoxin
09:37with an LD50 of 9.208 micrograms per kilo.
09:41Because its venom is so unique,
09:43there is almost no pain and almost no swelling.
09:46However, a few hours after the bite,
09:48symptoms such as double vision,
09:50flu-like symptoms,
09:51and difficulty breathing appear.
09:53All crate species eat different animals,
09:56such as fish and frogs.
09:57But they can also eat other snakes,
10:00even their own species.
10:01Even though these snakes are dangerous,
10:03they are gentle and calm,
10:05and only attack when truly threatened.
10:09Number
10:11Dubois sea snake
10:14From here, we will stay around Australia
10:17and the Indian Ocean
10:17as we look at the top 5 most venomous animals in the world.
10:22Most sea snakes are highly venomous,
10:24but the Dubois sea snake is the most dangerous.
10:27It has an LD50 of 44 micrograms per kilo,
10:29making its neurotoxic and hemotoxic venom extremely potent.
10:34Have you ever seen a moray eel?
10:36These are the eels with large jaws
10:38and a second set of jaws from their throat,
10:40used to swallow their prey.
10:41The Dubois sea snake hunts
10:43and eats young moray eels.
10:45Because it can even bite human fingers,
10:48it's no wonder why the effect of this venom
10:50is so fast and so strong.
10:52But fortunately, sea snakes are gentle
10:54and only use their venom
10:56when they're being defensive.
11:00Number 4, sea wasps
11:05This creature has an LD50 of 40 micrograms per kilo,
11:09and it's the most dangerous
11:10and most venomous jellyfish in the world.
11:13Since 1884,
11:14it has been responsible for over 100 human deaths.
11:18The tentacles of sea wasps
11:19can reach up to 3 meters
11:21and are filled with thousands of tiny nematocysts,
11:24like microscopic poison darts
11:26that inject venom into the skin.
11:28Just one of these large creatures
11:30is enough to kill about 60 people.
11:33Usually the sting is mild,
11:35but if you get tangled with this jellyfish,
11:37you could die from cardiac arrest
11:39in just 2-5 minutes.
11:41According to the victims,
11:43the pain caused by the tentacle
11:44feels like being burned by hot iron
11:47wherever it touches the skin.
11:48There is an anti-venom for this,
11:50but if the sting is too strong,
11:52you might not make it back to shore.
11:57Number 3, eastern brown snake
12:01The eastern brown snake is known
12:03as the second most venomous snake in the world.
12:06Its cocktail of neurotoxins and blood coagulants
12:09has an LD50 of 36.5 to 50 micrograms per kilo.
12:14It is often found in farmlands
12:16because it is attracted to its main food,
12:19rats,
12:20which usually live close to people.
12:22The bite of the eastern brown snake
12:24can cause convulsions,
12:26dizziness,
12:27kidney failure,
12:28paralysis,
12:29and of course,
12:30death if left untreated.
12:31Even though it only ranks second
12:33among the most venomous,
12:34In Australia,
12:3660 out of every fatal snake bite cases
12:38are caused by the eastern brown snake.
12:40It's as if nature is saying
12:42Australia really isn't meant for people.
12:45Number 2,
12:47Inland Taipan
12:51The Inland Taipan,
12:52just a single drop of its venom
12:54is enough to win.
12:55That's why it's the most venomous snake
12:57in the world.
12:58It has an LD50 of 25 milligrams per kilo,
13:01which is extremely low,
13:02meaning it's extremely potent.
13:03A single Inland Taipan
13:05has enough venom
13:06to kill over 200,000 mice
13:09or more than 55 adult humans.
13:11And what's even more terrifying
13:12is that its venom
13:13seems to be made specifically
13:15to kill anything that moves.
13:17It has neurotoxin,
13:19hemotoxin,
13:19myotoxin,
13:20and possibly more.
13:21If not treated immediately,
13:23more than 80% of those
13:25bitten by it die.
13:26The tissues literally break down
13:28until the organs completely fail.
13:30In addition,
13:31the color of the Inland Taipan
13:33also changes from winter to summer,
13:35making it even harder to spot.
13:37Fortunately,
13:38it only lives in the remote parts
13:39of central Australia.
13:41But seriously,
13:42if you're afraid of snakes and spiders,
13:44why would you even live in Australia?
13:491. Geography Cone Snail
13:54Okay, let's be honest.
13:56Before you watch this video,
13:58did you ever think
13:58that the most venomous creature
14:00on the planet is a snail?
14:02The Geography Cone Snail,
14:03which is only about 6 inches
14:05when fully grown,
14:06has venom made up
14:07of hundreds of toxins
14:08and has an LD50 of 12,
14:10230,
14:1130,
14:11and of course,
14:13where can you find it?
14:13On the northern coast of Australia,
14:16which they say
14:16is perfect for a family vacation,
14:18the small tube
14:19sticking out of the shell
14:20is used to sniff out
14:21the scent of its victim.
14:23And the way it attacks,
14:24there's a hidden harpoon
14:25inside its mouth
14:26that it suddenly shoots out
14:27at its victim.
14:28The venom acts so quickly
14:30that people used to believe
14:31you only had time
14:32for one cigarette
14:33before you died.
14:34If you think about it,
14:35it makes sense
14:35why the venom
14:36of the Geography Cone Snail
14:37is so strong
14:38and so fast-acting.
14:40It's a snail.
14:40It can't really chase its prey,
14:42so it makes up for it
14:43with its venom.
14:44Now,
14:45you should remember
14:46that if you eat it
14:47and then you die,
14:48it's poisonous.
14:49If it bites you
14:50and you die,
14:51it's venomous.
14:52Now,
14:53do you know
14:53any other creature
14:54that we didn't include
14:55in the list?
14:56Let us know
14:56in the comments.
14:57And before we end,
14:58make sure to subscribe
14:59and watch out
15:00for our next video
15:01about the most poisonous animal.
15:03So once again,
15:04thank you so much
15:05for watching.
15:06This is Noel Polo TV.
15:08See you on my next video.
