10 MOST DEADLY Creatures Known To MAN
Human beings may be at the top of the food chain, but that doesn't mean they don't have to be wary of the world around them. People can perish in thousands of ways, from natural causes to some of Mother Nature's finest predators. In this video from Top10Archive, we will look at some of man's most predominant adversaries, listed by highest yearly approximate death toll and not by lethality. Please keep in mind that this list in not entirely accurate, as many sources contradict information and the numbers may vary greatly from year to year.
Like the Tsetse, the mosquito is an unaware killer, spreading disease by doing what it’s naturally inclined to do. With an impressive death toll of close to 1,000,000 people per year, the mosquito reigns supreme as the top contender for man’s largest adversary. Diseases like West Nile and Malaria are common among the many diseases that mosquito’s can spread. Through the transmission of blood via the mosquito’s feeding process, outside of complete eradication, there’s really no stopping these buzzing menaces from continuing their inadvertent slaughter.
With over 3,400 species of snakes out there, there are bound to be a few that are less-than-friendly to humans. According to the 50,000 deaths per year by serpents, though, there may be far more than just a few. While the common cobra or rattlesnake are known for their toxicity, there are far more venomous snakes out there, like the Inland Taipan, the Eastern Brown snake, Black Tiger snake, and Western Australian Tiger snake. Those responsible for the most human casualties, though, are the Indian cobra, Common krait, Russell’s viper, and Saw-scaled viper; and while there is a polyvalent serum that neutralizes the venom, not everyone is fortunate enough to receive treatment in time. What’s more terrifying about these statistics is that non-venomous snakes are also responsible for quite a few deaths every year as well, mainly due to untreated bites that result in bacterial infections. A large majority of casualties resulting from snake bites are in parts of the world where anti-venom and treatment centers aren’t prevalent.
They’re cute, they’re cuddly, but in the wrong hands, they can be extremely dangerous. Domestic dogs can be tamed, but all it takes is an ill-fitted owner or someone with intent and a domesticated canine can turn into a vicious killing machine. On a yearly average, domestic dogs are responsible for 30 to 180 deaths per year – if one were to only consider mauling. What puts domestic dogs so high on this list is when rabies is considered, which increases their number from 30 deaths per year to closer to 25,000.
The Tsetse Fly
The Tsetse fly. Sounds like a harmless enough insect, but the Tsetse is up there as one of Africa’s most famed killers. The Tsetse doesn’t rely on powerful maws or impressive weight to take down a person – in fact, the creature likely doesn’t even know it’s about to kill an individual with just one simple bite. The Tsetse is known for its disease transmission and is responsible for over 10,000 deaths per year, as seen in the case of the spread of African sleeping sickness – a disease with an 80% mortality rate. A widespread campaign against the insect has been undergone in parts of Africa and include pesticides, trapping and slaughtering the Tsetse’s food supply. Photo: WHO/TDR
The Assassin Bug
The Reduviidae, or Assassin Bug, is a family of insects that houses the subfamily Traitominae – a bug know for being a fatal carrier of Chagas disease. These blood sucking insects inhabit parts of the Americas, from southern United States to northern Argentina. Much like mosquito’s, the Traitominae suck blood from living vertebrae, including humans, and wind up transmitting parasites like the Trypanosoma cruzi to their host. Trypanosoma cruzi, the parasite responsible for Chagas disease (or sleeping sickness, in Africa), will nest inside of a human, going unnoticed for upwards of 20 years before internal organs become affected. 20 to 30% of infected will suffer from enlarged heart ventricles, leading to eventual heart failure and death. This creature is the direct result of some 10,000 human beings every year.
The Freshwater Snail
Though they are a delicacy in some parts of the world, and pets to some, there is something malicious about the Freshwater Snail that all must be wary of. Schistosoma, a kind of flat worm parasite, are responsible for a high amount of human deaths per year, easily reaching 10,000 people. Schistosoma, also known as blood-flukes, is directly responsible for Schistosomiasis, a disease that could lead to liver damage, kidney failure, or bladder cancer. The disease is symptomized with diarrhea, abdominal pain, bloody stool, and traces of blood in urine. Once infected by Schistosoma, any human being could become a breeding ground, with the parasites eggs being laid in anywhere from the bladder to the kidneys.
Of the 1,500 species of scorpion out there, only 25 are equipped with a deadly venom. Regardless of only roughly 1% of the scorpion population being deadly, these arachnids are still responsible for approximately 3,000 human deaths a year. When it comes to human and scorpion interaction, it is extremely rare for a scorpion to sting a human just for the fun of it. The venom of a scorpion is often used primarily as a defensive mechanism against predators rather than offensive against prey. When traversing territory known for its scorpion population, it is best to look before you step – else you may be on the wrong end of a stinger.
Terrifyingly keen underwater and deceptively fast on land, crocodiles are a fascinating species responsible for nearly 2,500 deaths per year. These stumpy little reptiles come equipped with mandibles capable of a bite force of more than 5,000 lbf – or pounds of force – one of the highest bite forces recorded out of any creature. What makes the crocodile such an effective killer is its stealth-like tactics, its low stature making its scaly hide difficult to see among high brush. Once trapped in its strong jaws, escape is an unlikely scenario. In the water, the crocodile is an even deadlier animal.
The largest roundworm found in humans, the Ascaris Roundworm has another frightening truth to it – it is inadvertently responsible for up to 2,500 human deaths per year. Humans playing host to the Ascaris Roundworm may also be infected with Ascariasis, a disease that typically effects the abdominal portion of the body. How does one contract such a disease? Like the Pork Tapeworm, by ingesting food or beverages infected with Ascaris Roundworm larvae or egg. The Ascaris turns its host into a living, breathing breeding ground for more of its kind; and the more worms that are present, the more prevalent the disease will become.
One form of Tapeworm, the Pork Tapeworm, has a direct link to Cysticercosis, a tissue infection that is responsible for approximately 1,200 to 2,000 deaths per year. Typically contracted by eating under-cooked pork, the Pork Tapeworm’s egg is essentially the leading cause for the disease. Effects to the nervous system, muscles, eyes, and skin typically follow infection of Cysticercosis, with seizures, typically in third world countries, being a sign of the disease. Most deaths are caused from the lack of prevention and treatment centers.
