The World's deadliest animals

When considering the deadliest animals, it’s important to include humans in the discussion. While humans possess intelligence, technology, and the ability to reason, our actions and behaviors have had a significant impact on the environment and other species, including other humans, making us one of the deadliest creatures on Earth and the planet as a whole.

World's deadliest animals

  1. Mosquitoes are responsible for transmitting deadly diseases to humans and animals, causing almost million of deaths worldwide each year.
  2. While humans may not possess the physical prowess of other deadly animals, our species' impact on the environment and other living beings has been immense. Through activities such as deforestation, pollution, hunting, and warfare, we have significantly contributed to the decline and extinction of many species, leading to devastating consequences for ecosystems worldwide.
  3. Some snake species, such as the inland taipan and black mamba, possess venom that can be lethal to humans. Snakebites are a major health concern in certain regions of the world, resulting in thousands of deaths annually.
  4. Sandflies, also known as biting midges or no-see-ums, are tiny blood-feeding insects found in various regions around the world. Iin certain areas, sandflies can be vectors for certain diseases, particularly leishmaniasis.
  5. Surprisingly, dogs can also be considered one of the deadliest animals, but this is mainly due to their close association with humans. While dogs are often loyal companions, they can cause fatal injuries through attacks and bites, resulting from aggression or irresponsible ownership.
  6. Kissing bugs, also known as triatomine bugs, are blood-feeding insects found in the Americas, particularly in South and Central America, as well as parts of North America. The bugs get their nickname from their tendency to bite humans, often around the face, particularly near the lips.
    Kissing bugs are vectors for a parasitic disease called Chagas disease, also known as American trypanosomiasis. The disease is caused by the parasite Trypanosoma cruzi, which is transmitted to humans and animals through the bug's feces. When the bug bites and feeds on blood, it may defecate near the wound, allowing the parasite to enter the body through mucous membranes or breaks in the skin.
    Chagas disease can have acute and chronic phases. In the acute phase, symptoms may include fever, fatigue, body aches, and swelling at the site of the bite. However, many infected individuals may remain asymptomatic during this phase. If left untreated, Chagas disease can progress to the chronic phase, which may involve severe cardiac and gastrointestinal complications.
    Estimating the exact number of deaths caused by Chagas disease can be challenging due to varying levels of underreporting and limited access to healthcare in affected regions. According to the World Health Organization (WHO), an estimated 8,000 - 10,000 deaths from Chagas disease occur each year. However, this number may be higher since many cases go undiagnosed and unreported, particularly in rural and impoverished areas where the disease is most prevalent.
  7. Freshwater snails are known to be intermediate hosts for several parasitic diseases, particularly schistosomiasis, which is caused by trematode worms of the genus Schistosoma. Schistosomiasis is also known as bilharzia or snail fever.
    When freshwater snails release cercariae (the larval stage of the Schistosoma parasite) into the water, these larvae can penetrate the skin of individuals who come into contact with contaminated water during activities such as swimming, fishing, or washing clothes. Once inside the human body, the larvae develop into adult worms, which can cause a range of health problems, including damage to the liver, intestines, and other organs.
    Schistosomiasis is a significant public health concern, particularly in sub-Saharan Africa, South America, the Caribbean, the Middle East, and parts of Southeast Asia.
  8. Scorpions are venomous arachnids found in various parts of the world. Their venom is primarily used to paralyze or kill prey, and while most scorpion stings are not lethal to humans, some species can deliver venom that can be dangerous, particularly to vulnerable individuals such as children, the elderly, or those with allergies or underlying health conditions.
  9. Blood-feeding Tsetse Flies are notorious for transmitting the parasite that causes sleeping sickness in humans and animals, a potentially fatal disease if left untreated.
  10. Ascaris lumbricoides, commonly known as the giant intestinal roundworm or simply ascaris, is a parasitic worm that infects the human intestines. It is one of the most common and widespread intestinal parasites in the world. Ascaris infections are transmitted through the ingestion of food or water contaminated with the eggs of the worm.
  11. Tapeworm infections in humans, also known as cestodiasis, occur when individuals ingest tapeworm larvae or eggs, typically through contaminated food or water. Once ingested, tapeworms can attach themselves to the intestines and grow, causing a condition known as taeniasis.
  12. In most cases, taeniasis is not life-threatening and may not cause severe symptoms. However, complications can arise when tapeworm larvae migrate to other parts of the body, causing a condition called cysticercosis. Cysticercosis can be serious and potentially fatal, especially when the larvae reach vital organs like the brain.
  13. Crocodiles are powerful predators and, in some circumstances, can be dangerous to humans if they feel threatened or are protecting their territories. The number of fatal crocodile attacks tends to vary from year to year and depends on factors such as human behavior, crocodile populations, and the effectiveness of conservation and management efforts.
  14. While hippos are herbivores and primarily feed on vegetation, they can be extremely aggressive and dangerous, especially when they feel threatened or perceive intrusions into their territories. Hippos are known to be responsible for a significant number of human deaths in Africa each year, particularly in regions where humans come into close contact with these animals.
  15. Lions are apex predators and, although they are generally cautious around humans, they can be dangerous under certain circumstances.
    Lion attacks on humans typically occur in areas where human settlements encroach upon their natural habitats or when lions become injured, old, or unable to hunt their usual prey. Additionally, situations where humans provoke or approach lions in the wild can also lead to dangerous encounters.
  16. Bee stings can be painful and, in some cases, life-threatening, particularly for individuals who are allergic to bee venom. An allergic reaction to bee stings can result in a severe condition called anaphylaxis, which can lead to difficulty breathing, a drop in blood pressure, and, in extreme cases, death.
  17. Tigers are large and powerful carnivorous predators, but they are not typically a significant threat to human populations. Unlike some other big cats, tigers generally avoid humans and prefer to hunt and live in remote and secluded areas away from human settlements. Fatal tiger attacks on humans are relatively rare, but they do occur under certain circumstances. In areas where human activities encroach upon tiger habitats, and the natural prey of tigers is scarce, the likelihood of conflicts and dangerous encounters may increase.
  18. Jellyfish are marine creatures that have tentacles equipped with stinging cells used to capture and immobilize their prey. While most jellyfish stings cause discomfort, redness, and itching in humans, the vast majority are not life-threatening. However, some jellyfish species have venom that can be dangerous and, in rare cases, deadly to humans.
  19. Fatal wolf attacks on humans are incredibly rare. Historically, there have been very few confirmed cases of wolves killing humans, and such incidents are highly unusual. Wolves are generally shy and elusive animals that prefer to avoid contact with humans.
  20. Fatal shark attacks on humans are also relatively rare. Sharks are often portrayed as dangerous predators in popular media, but the actual risk of being attacked and killed by a shark is very low. While there are hundreds of shark species, only a few are considered dangerous to humans.

Moose population in North America

The moose population in North America is shrinking swiftly. This decrease has been correlated to the opening of roadways and landscapes into this animal's north range.   In North America, the moose range includes almost all of Canada and Alaska, the northern part of New England and New York, the upper Rocky Mountains, northern Minnesota and Wisconsin, Michigan's Upper Peninsula, and Isle Royale.    In 2014-2015, the North American moose population was measured at around one million animals. The most abundant moose population (about 700,000) lives in Canada. About 300 000 moose remains in nineteen U.S. states Alaska, Colorado, Connecticut, Idaho, Maine, Massachusetts, Minnesota, Montana, Michigan, Nevada, New Hampshire, New York, North Dakota, Oregon, Utah, Vermont, Washington, Wisconsin, and Wyoming. The largest moose specimens are found in Alaska 200 thousand moose. Below the map shows the size of US states scaled by the moose population.     Via www.vividmaps.com

Human Emotions Visualized

Despite significant diversity in the culture around the globe, humanity's DNA is 99.9 percent alike. There are some characteristics more primary and typical to the human experience than our emotions. Of course, the large spectrum of emotions we can feel can be challenging to verbalize. That's where this splendid visualization by the Junto Institute comes in. This visualization is the newest in an ongoing attempt to categorize the full range of emotions logically. Our knowledge has come a long route since William James suggested 4 primary emotions: fear, grief, love, and rage. These kernel emotions yet form much of the basis for current frameworks. The Junto Institute's visualization above classifies 6 basic emotions: fear, anger, sadness, surprise, joy, love More nuanced descriptions begin from these 6 primary emotions, such as jealousy as a subset of anger and awe-struck as a subset of surprise. As a result, there are 102 second-and third-order emotions placed on this emo
