Here are a few of the most horrific Invasive
species on Earth! 6 – Snakehead Fish A fish with shark-like teeth and the ability
to walk on land probably sounds like the things of nightmares. But the Northern Snakehead is all too real. Just ask Maryland natives who discovered the
fish in a pond in 2002, when they quickly annihilated the other species in the pond. Native to Asia and Africa, Snakeheads have
spread to waters all over the globe over the past century. This is bad, because when they’re introduced
to unnatural habitats, they have no natural predator and basically have free reign to
eat whatever they feel like, which can really throw the ecosystem out of order. Dubbed “Fishzilla” by National Geographic,
this freak-like fish can survive on land for up to 4 days, and the average female can produce
about 150,000 offspring during her life, making the population impossible to control. The fish were legally imported into the States
to display in aquariums and to eat, since they look kinda cool and they’re considered
a popular dish in Asia. But their presence has really disrupted fishing
trade as their population has spread all across the Potomac River System. They’ve even been spotted in Florida, North
Carolina, California, Hawaii, Rhode Island and Massachusetts. So you can see why a fishermen in the Americas
might hate these things so much. That’s why it’s now illegal to own live
Snakeheads in most U.S states who consider them to be a destructive invasive species. The real question is, how has there not been
a really bad B-movie made about this? If Sharknado gets five movies, why hasn’t
there been a film called “The Invasion of Fishzilla?” Fish that can live on land, bite the crap
out of you and mess up your ecosystem? C’mon let’s make this happen!! 5 – The Cane Toad Although the Cane Toad is native to the Americas,
it has spread across island nations in the Caribbean and Oceania, and has even managed
to weasel its way up into Northern Australia. By no stretch of the definition is this an
awesome thing. As an invasive species, Cane Toads often wreak
havoc on native species when they are first introduced to a new ecosystem. In the more than 20 countries the cane toad
have “invaded”, many of the countries saw a pretty serious decline in biodiversity. In Australia for example, after these pesky
toads moved on in, the populations of Northern Quolls, which is a tiny little creature that
roams the Northern Territory of Australia, were greatly reduced. They’ve been in rapid decline thanks to
the Cane Toads invading their territory, and are currently classified as an “endangered
species.” Merten’s Water Monitors, a small lizard
that calls Australia home, have also seen a huge decline in their ranks thank to these
annoying toads. Cane toads were introduced to Australia from
Hawaii in June 1935 in an attempt to control the native grey-backed cane beetle and Frenchi
beetle. These beetles are native to Australia and
they’re detrimental to sugar cane crops, which are a major source of income for Australia. Cane toads were to replace the use of pesticides
such as arsenic and copper. The cane toads bred immediately in captivity,
and by August 1935 more than 102 young toads were released. Since their release, toads have rapidly multiplied
in population and now number over 200 million and have been known to spread diseases affecting
local biodiversity! Unfortunately, the introduction of the toads
has not only caused large environmental detriment, but the toads didn’t do much to stop the
beetles, but instead became pests themselves. Let’s just say it didn’t work out too
well to say the least. 4 – European Starling While Alfred Hitchcock got some people really
freaked out by birds, on the surface, an army of songbirds doesn’t really sound all that
bad, which is probably why Eugene Schieffelin figured he’d release 60 of them into Central
Park in 1890. As their name would suggest, they’re native
to Europe, not the US. A drug manufacturer and literary fanatic,
Schieffelin figured he’d introduce every bird mentioned in Shakespeare’s work to
North America. Can I get some of whatever THIS guy was smoking? Anyways, thanks to a very brief mention of
the bird in Henry the VI, the 60 European Starlings that were first let loose in Central
Park have ballooned into 150 million. 60 to 150 million in around 120 years, wow. European starlings have gone on to cause upwards
of $800 million in crop damage each year. Of course the intentions here were pretty
innocent. I mean, many people have found weird ways
to pay homage to their favorite artists. And unless you’re a biology expert or something,
how would you know that they would grow like that? And their population has spread all over the
world to something like 310 million, because european starlings had been imported to different
because of their ability to control pests, pollinate crops and perform a handful of other
functions. However, when introduced to a new ecosystem,
european starlings can cause pandemonium. Common starlings can eat and damage fruit
in orchards such as grapes, peaches, and olives. They may also eat animal feed and distribute
seeds through their droppings. In eastern Australia, weeds such as bridal
creeper, blackberry and boneseed are thought to have been spread by common starlings. Starlings’ droppings can contain a fungus
which causes histoplasmosis in humans, which is a type of lung infection. At roosting sites this fungus can thrive in
accumulated droppings. There are a number of other infectious diseases
that can potentially be transmitted by common starlings to humans. The large size of flocks can also cause problems. Common starlings may be sucked into aircraft
jet engines, one of the worst instances of this being an incident in Boston in 1960,
when sixty-two people died after a turboprop airliner flew into a flock and plummeted into
the sea at Winthrop Harbor. So yeahhhhh, these guys can for sure be a
pretty serious problem. 3 – Burmese Python They’re one of the largest snakes on the
planet, sometimes reaching an astonishing 18 feet in length. Armed with razor sharp teeth and the ability
to suffocate large prey such as deer, pigs and goats, pythons are pretty damn scary. Because their population has skyrocketed in
the Florida everglades, Burmese Pythons are considered to be an invasive species. By some estimates, more than 1,300 of these
giant snakes roam the woods of Florida. Initially they were sold to Americans as exotic
pets, but because they’re often released into the wild, their population has grown
incredibly large. In 2012, the U.S Department of the Interior
banned the importation of Burmese Pythons because of the devastating effect they’ve
been having on South Florida’s ecosystem. For example, in Florida, they’re known to
be opportunistic predators, often wrangling up foxes, rabbits, possums, white tailed deer,
panther and racoons. Without a predator to keep them in check,
they treat the Everglades as their own personal buffet and all of these populations are thought
to have been dramatically impacted by the snake’s presence in Florida. Since they’re native to parts of Southeast
Asia, as their having the name “Burmese” in the name would suggest, they can only survive
in climates similar to that. That’s why they have been thriving in Florida. So while it’s unlikely that they’ll spread
across the U.S, they’re still causing mayhem in Florida. 2 – Redback Spiders Thumbnail: Here’s the thing about Redback Spiders. On top of being really invasive, they’re
also super poisonous. Which really isn’t a great combination. Their painful bite has earned them a fearsome
reputation in Australia, where natives consider them to be among the most dangerous of spiders. During the 1980’s, Brisbane noticed a huge
influx of these dangerous spiders. Redbacks are known to prefer a dry climate,
which is weird, because Brisbane sports a pretty moist, subtropical climate. But, the 80’s saw a more dry climate in
Brisbane, which allowed the redback population to grow tremendously. This was a problem, because Redbacks prefer
to live where humans do. The garden, the woodshed, the attic, the basement,
window seals, patio furniture, you name it, and Redbacks probably will try to make it
their home. And the problem seems to be a recurring one,
as Brisbane and really Queensland as a whole is currently experiencing another outbreak
of Redbacks. The intense summer heat wave is likely the
cause for the population explosion, much to the chagrin of Brisbane natives. These guys bite around 2000 people each year. Their bites can really screw up your day if
you’re unlucky enough to be attacked. The weird thing is, the bites often go unnoticed
at first, which is bad because that allows the venom to spread. Eventually the pain becomes really intense,
which often disrupts anyone’s day-to-day activities. Nausea, vomiting, headaches, and lethargy
are staple side effects of a redback bite. Though not typically fatal, there was recently
an extreme case. Take the Burleigh family, for instance. They tragically lost their 22 year old son
Jayden to a redback bite in April of 2016. Jayden landed in the hospital after being
bitten by a spider, and was released four days later with antibiotics. However, an abscess had formed under his arm
which infected his glands. That’s what was believed to have killed
him two days after leaving the hospital. To make matters worse, Jayden’s 17-year
old brother had been killed eight months earlier in a car wreck. Ah… about tragedy. As awful as his death was, Jayden is the first
person to die from such a bite in more than 60 years. Ever since the introduction of an effective
antivenom, most people have been able to survive the bites. Redback spiders even seem to be spreading
outside of Australia. In 2014, Redbacks were found in Tokyo for
the first time ever. This could have been pretty awful since Japan
wasn’t ready to treat an outbreak in bites. While this invasion didn’t seem to lead
to any real problems, it does prove troublesome. Who knows where they may end up next. With the influx of Redbacks it seems likely
that there will be more and more spider bites. The BBC reported that a man was bitten on
the p*nis by one the annoying spiders when he was using a portable bathroom. Um…….yeah, I think that’s on any guy’s
list of worst things that can happen. As god awful as that was, he survived the
ordeal after going to the hospital. Though he was reported to experience lots
of sweating, vomiting and nausea, he was later released in stable condition with hopefully
fully functioning equipment and I assume a newfound appreciation for anti-venom. 1 – Black Rats Since black rats were thought to be an accomplice
in the spread of the Black Death, which killed around 100 million people in Europe during
the 14th century, one could argue they’re among the worst invasive species of all time. In fact, they may just take the cake. One of the more widely accepted theories as
to how the black death, or also known as the bubonic plague, spread was that fleas carrying
the plague latched onto black rats, who were pretty common on merchant ships, and helped
spread the plague all across Europe. We’ve all heard about the black death, and
we know that it wiped out a huge portion of the world’s population. It wasn’t until the 17th century and the
industrial revolution that the population recovered. But what was the plague actually like? I have no clue, but I can only guess that
it sucked. Those infected would grow buboes which cause
lymph nodes to swell up, sometimes to the size of apples, according to historical accounts. These buboes would often ooze pus and bleed
when they popped or opened. Black spots would form all over the body which
was likely the result of dead flesh (hence the name black death.) People would then develop really bad fevers
and start vomiting blood. In most cases, those infected wouldn’t last
even a week. At the time, they figured the plague was spread
airborne. They thought it was simply bad air. The concept of hygiene was a pretty foreign
concept, which is why most cities had discarded food, trash and piles of human sh*t all over
the city. This made it ripe breeding ground for the
rats who came over on merchant ships, who carried over the fleas, which then caused
the plague to spread like wildfire. Now, some historians have presented some pretty
lucid evidence to suggest that the plague was actually spread person to person, and
not by rats. Even if that is the case, and who knows if
it is….black rats are still considered to be a pest to this day. Like pretty much all other invasive species
they invade an ecosystem, and royally f**k it up. Rats have been especially destructive on sub-arctic
tropical islands. Without a natural predator, they grow uncontrollably,
and prey on other species, and are responsible for the extinction of many species on tropical
islands. Seriously, who likes rats?! Here’s what’s next!
