From one creature that held back the economy
in Africa to another that wrought bell in a Brazilian community, here are 8 tiny animals
that can destroy: Today’s video was done in collaboration with
Bored Badger. Stay tuned until the end of the video to find
out more. Number 8 Tsetse Fly
Even though tsetse flies resemble common houseflies in appearance, they are nothing alike when
it comes to the dangers they pose for human beings. These creatures are much tougher than houseflies,
which are usually easily crushed with a flyswatter. Tsetse flies are equipped with a long proboscis
which they use to feed on the blood of vertebrate animals. They are known carriers of trypanosomes, organisms
that cause human sleeping sickness. This is a debilitating disease which can result
in the swelling of the brain. It affects thousands of people each year,
particularly in Africa. Historically, the tsetse fly has had a significant
economic impact in large regions of sub-Saharan Africa by inhibiting human settlement and
agriculture. Number 7 bus Caterpillar
The bus caterpillar is the larval form of the southern flannel moth and it can be found
in various parts of the United States, Mexico and Central America. Its preferred habitat consists of elms, oaks,
wild plum as well as numerous garden plants such as rose and ivy. It usually measures around one inch in length. The ‘bus’ part of its name presumably
comes from its resemblance to a Persian cat, due to its long, luxuriant fur-like bristles. The caterpillar is considered a dangerous
insect because the ‘fur’ that covers it’s body has venomous spines which can cause extremely
painful reactions upon contact with human skin. Some patients have compared the pain to broken
bones or blunt force trauma. More severe reactions can include numbness,
headaches, chest pains or difficulty breathing. Number 6 Tarantula Hawk
When asked about the sting of the tarantula hawk, one researcher described the physical
reaction as ‘immediate, excruciating, unrelenting pain that simply shuts down one’s ability
to do anything, except scream. Mental discipline simply does not work in
these situations.’ Tarantula hawks have very large stingers which
is why few predators are able to eat them. According to the Schimdt sting pain index,
this wasp owns one of the most painful stings in the animal kingdom. Its filling technique, which it mainly employs
when hunting tarantulas, is also quite brutal. It has long legs ending in hooks which it
uses to grapple its victim. The tarantula hawk will then sting its prey,
paralyzing it, and drag it to a brood nest as living food. Once this is done, the wasp will lay a single
egg on its prey, which hatches into a larva that starts eating at the victim while it’s
still alive. Tarantula hawks can be found in regions ranging
from India to Southeast Asia, Australia, Europe, Africa and the Americas. They are among the largest wasp species, measuring
up to 2 inches in length. Their bodies have a bright blue-black coloration
and bright, rust-colored wings. These colors act as a warning against potential
predators. Number 5 Irukandji Jellyfish
With a bell that rarely exceeds one inch in width, the Irukandji jellyfish is one of the
smallest jellyfish species in the world. That doesn’t mean it isn’t as-or-more
dangerous than its larger counterparts. It has four thin tentacles which can reach
up to 3.3 feet in length. Unlike other jellyfish species that only have
stingers on their tentacles, the Irukandji jellyfish also has stingers on its bell, a
unique adaptation that researchers have yet to figure out. Its size and fragility make studying it quite
difficult which is why not much is known about its venom and life cycle. The fact that the jellyfish is very small
and transparent also makes it hard to spot in the water. On average 50 to 100 people end up in the
hospital from Irukandji jellyfish stings each year. Its venom has been described as 100 times
stronger than that of a cobra and 1,000 times more potent than that of the tarantula. It’s so powerful that it can cause fatal
brain hemorrhage. The symptoms associated with certain species
of Irukandji Jellyfish are collectively known as Irukandji Syndrome. Aside from physical effects such as severe
back and kidney pain, headaches, vomiting, nausea, or sweating it also reportedly induces
a psychological effect described as the feeling of impending doom. These symptoms can last from a couple of hours
to several weeks and the victims often require hospitalization. Number 4 Blue Ringed Octopus
When considering its small size of only 5 to 8 inches, it’s hard to believe that the
blue ringed octopus is one of the most venomous animals in the world. This deadly marine creature has yellowish
skin and blue-black rings that change color as a warning display, whenever it feels threatened. That’s when the body turns bright yellow
and the rings start flashing bright iridescent blue within a third of a second. These rapid flashes tell would-be predators
that they are taking on an exceptionally dangerous creature. Despite their docile demeanor, blue ringed
octopi have venom which contains a powerful neurotoxin called tetrodotoxin. These tiny creatures hold enough venom to
fill 26 adult human beings within minutes and there isn’t any known blue-ringed octopus
anti-venom available. If that isn’t scary enough there’s also
the fact that their bites are tiny and usually painless. This means that by the time the symptoms set
in, it might be too late. The effects of blue-ringed octopus envenomation
on human beings is devastating and may lead to nausea, respiratory arrest, heart failure,
blindness as well as partial or total paralysis. Tetrodotoxin, which is 1,200 times more toxic
than cyanide, is produced by bacteria in the octopus’ salivary glands. Tetrodotxin envenomation can result in the
victim being unable to move while still being completely aware of their surroundings. Without treatment, bath may occur within minutes
and it’s usually caused by suffocation as a result of diaphragm paralysis. Number 3 Ticks
These tiny arachnids rarely measure more than 0.20 inches but they are very dangerous because
of their ability to transmit diseases. They’re widely distributed all-over the
world but tend to prefer warm, humid climates. There are two major tick families: the Argasidae,
also known as soft ticks and the Ixodidae, or hard ticks. They live by packing the blood of other animals,
including birds and mammals as well as certain types of reptiles and amphibians. They have eight legs and oval or pear-shaped
bodies that become engorged with blood whenever they feed. Ticks are vectors of at least 12 diseases
that affect humans and other animals. They are involved in the transmission of bacteria,
viruses and parasites. Among the many tick-borne diseases there’s
typhus, Rocky Mountain spotted fever, Colorado tick fever, Q fever, Lyme disease and others. Some species, such as Ixodes Holocylus are
also venomous and may cause tick paralysis. Only one other creature surpasses the tick’s
disease-barring ability. Number 2 Mosquitoes
It may be hard to believe but the tiny mosquito is actually the deadliest animal on Earth. No animal is safe from this blood-thirsty
creature as it feeds on mammals, reptiles, birds, amphibians, even on certain types of
fish or invertebrates. Mosquitoes belong to the Culicidae family
and draw their names from the Spanish term for ‘little fly’. Females of the species have a tube-like mouthpart,
called a proboscis, which they use to pierce the skin of their victim to consume their
blood. There are more than 2,500 mosquito species
and many of them have evolved resistance against commonly-used insecticides. They have even changed their feeding habits,
feeding outside and earlier, to avoid insecticide-sprayed homes and bed nets. It seems that mosquitoes can adapt to whatever
human beings throw at them. These vampire-like creatures are responsible
for more human baths each year than all other animals on the list combined. This is because mosquitoes are carriers for
a plethora of diseases which they can transmit from host to host. These include infections like yellow fever,
dengue fever, malaria, Zika virus, West Nile virus, filariasis, and more. Business magnate and well-known humanitarian
Bill Gates commented on how dangerous these creatures are, stating ‘The worst is malaria,
which fills more than 600,000 people every year; another 200 million cases incapacitate
people for days at a time. It threatens half of the world’s population
and causes billions of dollars of lost productivity annually’. Number 1 Lonomia Caterpillar
Lonomia obliqua, also known as the giant silkworm moth, is a creature that’s most dangerous
in its larval form. The caterpillar’s bristles inject venom
that’s strong enough to fill adult human beings. The lonomia obliqua caterpillar measures around
2 inches in length with colors ranging from brown to green and it’s typically well camouflaged. Rows of tubercles make up the caterpillar’s
body and they are crowned with whorls of detachable spines that vary in size. Each of these clumps of spines can pierce
the victim’s skin and release potent toxins. These caterpillars can be found in southern
Brazil, Paraguay, Uruguay and Argentina. It became known worldwide after an epidemic
occurred in a community in Rio Grande do Sul, Brazil. Local physicians were dumbfounded as numerous
patients started coming with gangrene-like symptoms that manifested throughout their
bodies. Some of them died from massive blood leakage
in the brain. Eventually it was found that the lonomia obliqua
was the common factor in all of the incidents. So far, there have been at least 500 recorded
baths caused by the caterpillar. The toxins in its skin hold potent anti-clotting
agents. They cause massive internal bleeding that
spreads through the organs, eventually leading to compression and brain bath.
