Injected directly into the flesh by long fangs,
needle-sharp harpoons, by tentacles, or even by spitting, venom is the weaponized chemistry
used in the animal kingdom. In any list of the world's most venomous animals,
snakes often get top billing, but venom is used by many other species and though it may
not be intended for humans, we often fall afoul of these nasty toxins by strolling or
swimming in the wrong place. Which are they most dangerous of all? That’s what we’ll find out today, in this
episode of The Infographics Show: Deadliest Animal Venom. 10. The fugu fish
The fugu Fish is a puffer fish eaten as a delicacy in a number of Asian countries, mostly
notably in Japan. But this fish also comes with a nasty toxin
known as tetrodotoxin, which is removed during preparation. The restaurant preparation of fugu is strictly
controlled by law in Japan and several other countries, and only chefs who have qualified
after three or more years of rigorous training are allowed to prepare the fish. And for good reason. The puffer fish poison produces a rapid and
violent death. If you ingest this nasty concoction, it causes
deadening of the tongue and lips, vomiting, dizziness, rapid heart rate, difficulty breathing,
and muscle paralysis. Victims eventually die from suffocation as
muscles in the diaphragm are paralyzed. Statistics from the Tokyo Bureau of Social
Welfare and Public Health indicate 20 to 44 incidents of fugu poisoning per year between
1996 and 2006 in Japan. 9. Poison Dart Frog
Poison dart frogs have some of the most vibrant skin colors on Earth. Depending on individual habitats, which extend
from the tropical forests of Costa Rica to Brazil, their coloring can be red, green,
blue, yellow, gold, copper, or black. But their colors are deliberately striking
to warn potential predators of their nasty taste, and this Frog is one of the most poisonous
animals on earth. The 2-inch (5 cm) long golden poison dart
frog has enough venom to kill 10 adult humans or 20,000 mice. As little as 2 micrograms of this lethal toxin,
which is the amount that fits on the head of a pin, is capable of killing a human or
other large mammal. They are called dart frogs because Central
and South American Indians use the venom on the darts they use for hunting animals. Poison dart frogs keep their poison in their
skins and will sicken or kill anybody who touches or eats them. Luckily it lives off the beaten track, so
human contact and known deaths are rare. 8. The inland taipan
The prize for he world’s most venomous snake goes to the Inland Taipan of Australia. The inland taipan, also known as the western
taipan, the small-scaled snake, or the fierce snake, is an extremely venomous creature. Just a single bite contains enough venom to
kill 100 human adults or an army of 250,000 mice, which make it 200 to 400 times more
toxic than a common cobra. The Inland Taipan’s extremely neurotoxic
venom can kill an adult human in as little as 45 minutes. But it’s not at number one in the list as,
fortunately, this snake is very shy and all known bites were treated with anti-venom,
with no record of a human ever being killed. 7. The Brazilian Wandering Spider
The Brazilian Wandering Spider is an aggressive and highly venomous spider that was first
discovered in Brazil, hence its name. It is also known to exist elsewhere in South
and Central America. This spider appears in the Guinness Book of
World Records 2007 for the most venomous spider, and it is the spider responsible for most
human deaths. Only 0.00000021oz (0.006mg) of its venom is
required to kill a mouse. They often hide during daytime in highly populated
areas inside houses, clothes, boots, and cars, which make it particularly dangerous to humans. Its venomous bite causes not only intense
pain, but also what is known as priapism, a condition of uncomfortable erections lasting
for many hours that lead to impotence. 6. The Stonefish
The stonefish is the most poisonous fish in the sea and one of the most dangerous in the
world. It can easily kill you if you step on it,
injecting its venom deep inside your foot. Its dorsal area is lined with 13 spines that
release the venom from two sacs attached to each spine. This nasty stuff causes severe pain with paralysis,
tissue death, and possible shock leading to death. Stonefish are bottom-dwelling fish that live
among rocks and coral in tropical waters, so take care, as they are not easy to spot. 5. Deathstalker Scorpion
Scorpions have been living on earth long before the birth of dinosaurs. These extraordinary hunters have been around
for 400 million years and they have evolved to be pretty good at what they do. There are more than 1,500 species of scorpions,
and though most are relatively harmless to humans, as stings produce only local effects,
the Deathstalker Scorpion is one dangerous critter. Its venom is a powerful cocktail of neurotoxins,
which causes unbearable pain, followed by fever, convulsions, paralysis, coma, and death. But deaths are rare, and it’s unlikely it
would kill a healthy adult, with young children and the old being more at risk. Deathstalker scorpions are found in North
Africa and the Middle East. 4. The Blue-Ringed Octopus
The Blue-Ringed Octopus is very small, only the size of a golf ball, but despite its small
and squishy stature, it is one of the ocean’s most venomous creatures, and it’s venom
is powerful enough to kill a human. The saliva of this little octopus contains
tetrodotoxin, a powerful nerve toxin that can cause muscular weakness, numbness, and
possible respiratory failure leading to death. It carries enough poison to kill 26 adult
humans and unfortunately there is no antidote. At least 3 deaths in Australia have been attributed
to blue-ringed octopuses. They can be found in tide pools in the Pacific
Ocean, from Japan to Australia. 3. Cone snail
Who would ever think an innocent looking snail could be deadly? Well this cute looking Cone snail is just
that. One drop of its venom is powerful enough to
kill more than 20 humans. There are about 600 different species, all
of which are poisonous. Cone snails live in shallow reefs buried under
sandy sediments, rocks, or corals in tropical and subtropical waters. Its venom is used to catch prey, but if you
accidentally step on one or pick it up, the consequences can be nasty. Symptoms of a cone snail sting can start immediately,
but can also be delayed for days. If you are victim of a cone snail, you’ll
feel intense pain, swelling, and numbness. Severe cases involve muscle paralysis, vision
changes, and breathing failure. There have been roughly 30 known human deaths
from Cone snails and there is no antivenom. 2. The King Cobra
The King Cobra is the world’s longest venomous snake and they can grow to a frightening 18.5
ft (5.6 m) in length. When confronted, they can rise up to one-third
of their bodies straight off the ground and still move forward to attack. So a large one would be face to face with
a human. Their head flairs out and they make a bone-chilling
hiss that sounds like a growling dog. One bite can cause the death of a healthy
adult human within 15 minutes. The venom is so powerful they are even capable
of killing a full-grown Asian Elephant. King cobras live mainly in the rain forests
and plains of India, southern China, and Southeast Asia. They are perhaps best known as the snake that
is used by snake charmers in South Asia, who coax them to dance from a basket. The charmer's flute entices the cobra by its
shape and movement, not by the music it emits. It’s hard to get exact statistics on deaths
from Cobras, but we do know that 46,000 people in India alone die each year from snakebites,
many of which are by Cobras. And the top prize for deadliest animal venom
goes to the Box Jellyfish. It has caused at least 5,567 recorded deaths
since 1954. It’s toxins attack the heart, nervous system,
and the skin cells. It can kill you within 5 minutes unless the
sting is treated. And it is so painful that victims go straight
in to shock, which can cause heart failure or drowning if it happens in deeper water. Survivors will experience pain for weeks after
being stung. Box jellies can be found in the waters around
Asia and Australia, and if you are unfortunate enough to come in to contact with one of these
nasty squidgy monsters, you need to apply the following treatment immediately…First,
rinse the area with vinegar; Vinegar contains acetic acid, which disables the box jelly’s
nematocysts. Then, carefully pluck visible tentacles with
a fine tweezers. And finally, soak the skin in hot water for
at least 20 minutes; Use water that's 110 to 113 F (43 to 45 C). If a thermometer isn't available, test the
water on an uninjured person's hand or elbow. It should feel hot, not scalding. So, that’s our top 10. Do you know of any other venomous animals
