TOP 10 DANGEROUS ANIMALS AROUND THE WORLD

TOP 10 DANGEROUS ANIMALS AROUND THE WORLD

Danger and especially dangerous creation fascinate us. We are constantly efforts to make a better and safer life for ourselves, but the world remains a dangerous place. As for wild animals, what determines their danger level might not necessarily be size. What we can formulate with our human brain power? We may think of some of these animals as friendly or harmless, but sometimes even friendly seeming species become dangerous. Here are the top 10 deadliest animals that could turn any human, smart or dumb, into a tasty lunch or dinner. Many more criteria are still out there. Feel free to add other deadly creatures to the comments.

10. Jellyfish


Affectionately known as the “sea wasp”. The Jellyfish killing more then 100 per year provides a good example of why these graceful, free-floating marine creatures can also be some of the world’s deadliest living organisms. They are mostly found around the Australian coastline, and are most commonly seen in the summer months. Just like any animal, however, jellyfish take no prisoners when they feel threatened. Box jellyfish don’t even drift; they actively swim to hunt their prey, and a nice human leg or arm can suffer some serious collateral damage.

9. The Shark

The shark’s most incredible, virtually X-Men ability is called electroreception. They have organs in their heads called Ampullae of Lorenzini. Every time any animal moves, it generates a very slight electrical field, and sharks can actually sense this electricity. Thus a person treading water looks like lightning to a shark. A great white can detect half a billionth of a single volt. If it is within 100 meters, it can detect the voltage of your heartbeat. Averaging 15 feet long, with rows of up to 300 sharp serrated teeth inside powerful 4-foot-wide jaws, the great white shark is comfortably at the top of the food chain. It eats a wide variety of species and isn’t too picky, but humans are not preferred, being leaner and bonier than its favorite prey—the fattier seals and sea lions.

8. Hippopotamus

After the elephant and rhinoceros, the hippopotamus is the third largest type of land mammal and the heaviest extant artiodactyl. They are usually found in Africa and are responsible for more human fatalities on the continent than any other large animal. Male and female hippos tend to have different reasons for attacking. A male hippo will defend its territory, which runs along the bank of a river or lake, whereas the female becomes aggressive in defending her young. They killed more then 200 every year.

7. Lion

A full-grown male lion is about 6 inches taller than a tiger and weighs anywhere from 330 to 550 lbs (150-250 kgs), averaging 400. Kings of the jungle and one of nature’s most brilliant predators, lions are fast, cunning and extremely powerful, they have a sixth sense for hunting and they aren’t very discriminating when it comes to a red-meat dinner. Lions are found on the plains of Africa, but are also held in captivity around the world in zoos and reserves. Lions simply see humans as slower, less-able free lunches, much like gazelles or a zebras. These caused over 250 deaths per year.

6. Cape Buffalo

Also known as “black death” the Cape buffalo, found in Africa, being one of the most dangerous animals on land. Killing more then 500 per year, one of Africa’s most dangerous beasts. It is extremely aggressive and unpredictable. It can weigh between 900 to 1800 pounds, and except for some lone bulls, this bovine species is very gregarious. Herd members are quick to defend each other from lions, crocodiles, or hunters, by ramming the predator with their sharp horns. Sometimes a wounded bull will circle around to ambush its hunter from behind.

5. Elephant

The elephant, the largest land mammal, lives in Africa and some parts of Asia. Normally viewed as friendly, caused over 600 deaths per year, can also be the most dangerous to human health. These lovable, circus-friendly icons can be found in Africa and South Asia, and in a lot of cases, can be found in urban areas where people use their services for tourism, trade and transportation. But, just like a frustrated employee, these hard-working, usually docile creatures never forget poor treatment or being threatened, and that’s why they lash out. An elephant’s legs, trunk, and weight can crush just about anything, and one moment of anger can be lethal.

4. Crocodile


Killing up to 2,000 of people a year, it takes is a good look at one of these prehistoric beasts to realize just how deadly they can be. Crocodiles can be found in the southern U.S., the Tropics, Africa, Asia, and Australia, and love the taste of human flesh just as much as that of any other unsuspecting animal it sees. The saltwater and Nile crocodiles are the most dangerous. It eats a wide variety of animals, living and dead. Its eyes, ears, and nostrils are located high on the head, which allows a crocodile to see and hear its prey. It ranges from 5 to 20 feet long.

3. Scorpion


Caused up to 5,000 deaths per year, Scorpions are predatory arthropod animals of the order Scorpiones within the class Arachnida. Found widely distributed over all continents, except Antarctica, in a variety of terrestrial habitats except the high latitude tundra, these eight-legged arthropods can pack a powerful punch. They are a resilient, non-parasitic killer that actually have the ability to distribute doses of venom based on the type of prey. Buthids, in particular, are the most deadly scorpions and are generally found in Africa, though deadly scorpions have been known to survive and thrive in bone-chilling environments, such as the Andes and the Himalayas.

2. Snake


Living snakes are found on almost every continent. More than 450 species are venomous, and 250 are capable of killing a person. Most venomous bites occur in Africa, Asia, and North America. These cold-blooded reptiles are also cold-blooded killers, and it always seems the further you get away from home, the deadlier they get. The toxicity of some snakes are incredibly severe. These things tend to kill humans for one simple reason: they feel provoked. Plain and simple: It’s their natural defense mechanism to lash out with razor-sharp teeth and sink venom into your skin. These caused 100,000-plus deaths per year.

1. Mosquitoes – Most Deadliest Animal




Mosquitoes make number one on the list of deadliest animal in world. This small blood-sucking insect kills 2 million to 3 million people each year worldwide. They are a family of small, midge-like flies: the Culicidae. Although a few species are harmless or even useful to humanity, most are a nuisance because they consume blood from living vertebrates, including humans. The females of many species of mosquitoes are blood eating pests. It can spread diseases, most notably malaria. Mosquitoes are found in abundance in tropical areas and can also survive the winter in countries with lower temperatures such as Canada. There are over 3,000 types of mosquitoes and all have the ability to transfer population-killing diseases.

10 Facts about human brain you have to know

10 FACTS ABOUT HUMAN BRAIN


The human brain is the most complex and least understood part of the human anatomy. There may be a lot we don’t know, but here are a few interesting facts that we’ve got covered.
  1. 1. Nerve impulses to and from the brain travel as fast as 170 miles per hour. Ever wonder how you can react so fast to things around you or why that stubbed toe hurts right away? It’s due to the super-speedy movement of nerve impulses from your brain to the rest of your body and vice versa, bringing reactions at the speed of a high powered luxury sports car.
  2. 2. The brain operates on the same amount of power as 10-watt light bulb.The cartoon image of a light bulb over your head when a great thought occurs isn’t too far off the mark. Your brain generates as much energy as a small light bulb even when you’re sleeping.
  3. 3. The human brain cell can hold 5 times as much information as the Encyclopedia Britannica. Or any other encyclopedia for that matter. Scientists have yet to settle on a definitive amount, but the storage capacity of the brain in electronic terms is thought to be between 3 or even 1,000 terabytes. The National Archives of Britain, containing over 900 years of history, only takes up 70 terabytes, making your brain’s memory power pretty darn impressive.
  4. 4. Your brain uses 20% of the oxygen that enters your bloodstream. The brain only makes up about 2% of our body mass, yet consumes more oxygen than any other organ in the body, making it extremely susceptible to damage related to oxygen deprivation. So breathe deep to keep your brain happy and swimming in oxygenated cells.
  5. 5. The brain is much more active at night than during the day. Logically, you would think that all the moving around, complicated calculations and tasks and general interaction we do on a daily basis during our working hours would take a lot more brain power than, say, lying in bed. Turns out, the opposite is true. When you turn off your brain turns on. Scientists don’t yet know why this is but you can thank the hard work of your brain while you sleep for all those pleasant dreams.
  6. 6. Scientists say the higher your I.Q. the more you dream. While this may be true, don’t take it as a sign you’re mentally lacking if you can’t recall your dreams. Most of us don’t remember many of our dreams and the average length of most dreams is only 2-3 seconds–barely long enough to register.
  7. 7. Neurons continue to grow throughout human life. For years scientists and doctors thought that brain and neural tissue couldn’t grow or regenerate. While it doesn’t act in the same manner as tissues in many other parts of the body, neurons can and do grow throughout your life, adding a whole new dimension to the study of the brain and the illnesses that affect it.
  8. 8. Information travels at different speeds within different types of neurons. Not all neurons are the same. There are a few different types within the body and transmission along these different kinds can be as slow as 0.5 meters/sec or as fast as 120 meters/sec.
  9. 9. The brain itself cannot feel pain. While the brain might be the pain center when you cut your finger or burn yourself, the brain itself does not have pain receptors and cannot feel pain. That doesn’t mean your head can’t hurt. The brain is surrounded by loads of tissues, nerves and blood vessels that are plenty receptive to pain and can give you a pounding headache.
  10. 10. 80% of the brain is water. Your brain isn’t the firm, gray mass you’ve seen on TV. Living brain tissue is a squishy, pink and jelly-like organ thanks to the loads of blood and high water content of the tissue. So the next time you’re feeling dehydrated get a drink to keep your brain hydrated.
