Updated on November 19, 2018

I have many interests and an inability to make up my mind about which one to focus on. That's how I came up with my name: ControlledChaos1.


Any animal can be dangerous under the right circumstances, but people need to be especially wary of wild animals. Animals that grow up in the wild must be given the proper respect, even those that are apparently "tame". Animals growing up in the wild must always be in fight or flight mode, which make some of them especially difficult to interact with. Add in any need to eat, and you have a dangerous situation. Enjoy their beauty; keep in mind their fierceness.

Wild Animals That Can Kill, Hurt or Maim

  • Cassowary: A large, brightly-colored bird of New Guinea that is known for its unpredictable and aggressive nature. Can cause serious harm with its kicks and large claws.
  • Moose: They may look friendly, but will aggressively charge and attack more often than bears in some cases. When in moose country be aware of when the mating season begins.
  • Snakes: The most lethal snakes in the world are usually ones that are hard to see and do not give any kind of warning before biting. Snakes don't search out large prey like us, so their bites are always defensive. A few of the more dangerous ones are the Inland Taipan, Death Adder, Copperhead, Eastern Brown Snake, Cottonmouth, Black Mamba, Coral Snake and the Boomslang.
  • Lanomia Caterpillar: This crawling assassin contains an anticoagulant venom that people find themselves getting a dose of because it can blend in so well with its surroundings. People from Brazil often get stung by leaning up against or grabbing trees and not seeing this intimidating creature. We can thank the heavens above the the giant moths they turn into are not poisonous.
  • Chimpanzee: People look at these creatures as cute animals, but keep in mind that they are five times stronger than humans and can cause serious problems for you if they decide to attack.
  • Mosquitoes: Mosquitoes prove that size doesn't matter when it comes to being lethal. They are easy to kill, but their numbers give this insect an edge. They are widely believed to cause more deaths than any other animal in the world, as they can pass along diseases such as Yellow Fever, Malaria, Zika Virus and West Nile Fever (all of which kill).

Deadly Ocean Creatures

Run for Your Life!

  • Hippopotamus: One of (if not the) most dangerous land animals in Africa. Very territorial, and very fast for its size. Most people see them as a cute animal instead of as a deadly animal, which is why it kills so many people.
  • Sloth Bear: In Sri Lanka and India they maul people every chance they get.
  • Africanized Honey Bee: An extremely ferocious insect that protects its hive with total conviction. Will chase and attack people without giving up.
  • Black Bear: The fact that most people don't consider this bear too dangerous is what makes it dangerous. I live in the Smokey Mountains where people love to interact and photograph these bears, but every decade or so, there are stories of hikers being killed by one. Stay cautious when around one, and fight back if attacked by one.
  • Giant Japanese Hornet: These are the largest hornets in the world and can reach almost 2 inches in length. They cause up to forty human deaths a year and their venom is capable of dissolving organic tissue. You don't want to poke this nest with a stick.


Cute but Dangerous... and Deadly

  • Beaver: You will always have a bad day if you have a run-in with an angry beaver.
  • Fire Salamander: Most animals use bright colors to warn predators that they are extremely poisonous. You have now been warned.
  • Red Fox: These can become very tame, but can never be fully trusted, and are especially dangerous to have around young children.
  • Blue-Ringed Octopus: One of the world's most venomous animals can usually be encountered by those wading in tide pools around Australia and Japan.
  • Human Beings: The most dangerous animal on our planet because their intentions are hard to predict and they have been known to kill for no reason whatsoever. On the flip side, they can also be the most caring and kind. Very unpredictable creatures.

When Animals Attack

More Dangerous Animals That You Should Watch Out For

  • Ostrich: Their kicks have been known to kill lions. The good news is that most reported attacks on humans have been because they were provoked.
  • Spiders: Some of the most poisonous spiders in the world are not always easy to tell apart, so it is best to avoid them altogether, though most bites come about by accidental run-ins with them. A few especially bad spiders include the Brown Recluse, Northern Funnel Web, False Widow and the Brazilian Wandering Spider.
  • Polar Bear: A bear that most people find the cutest, is actually one of the most dangerous. Do not approach.
  • Box Jellyfish: These animals not only have one of the most dangerous types of venom in the world, but the venom also causes extreme pain.
  • Hooded Pitohui: There are only a handful of poisonous birds in the world, and this one is fairly common if you pay a visit to New Guinea. This songbird contains a range of batrachotoxin compounds that can be found in its skin and feathers. The poison is related to that of the Poison Dart Frog and is thought to find its way to the bird because of its diet of poisonous beetles. As a result, the toxicity of individual birds can vary based on diet.


Domesticated Animals Can Also Be Dangerous

  • Chickens: Make no mistake about it, there is nothing more frightening (especially if you are a child) than being flogged by a chicken. They are most aggressive when protecting their young.
  • Dogs: Most of the time it is how the dog is raised and cared for that make the biggest impact on its nature, but there are breeds of dogs that are known to be a bit more dangerous than others. Breeds such as the Pitbull, Rottweiler, Chow Chow, Wolf Hybrid, Brazilian Mastiff, Boer Boel, Rhodesian Ridgeback and the German Shepherd are just a few that are known to be jealous, very protective or easily trained into doing bad things. Always be cautious when interacting with them.
  • Cows: Cows kill about twenty people a year in the U.S., and while they are mostly farm workers, that fact should make you think twice about going cow tipping. Large cows are quicker than they appear, powerful and often protective of their territory.
  • Horses: Most injuries by horses are by accidents, whether they be throwing someone off or trampling a person due to the animal being scared. Never underestimate how a hoof to the head or body can break bones and give concussions.

Animals You Better Be Glad Are Extinct

  • Megalania: These land-roaming lizards went as big as 1300 lbs and 23 ft. long, and made their home in Australia as little as 50,000 years ago. As with the Komodo Dragon, these lizards had a venomous bite to slow down their prey, which made them the largest venomous vertebrate known to exist. Fossils are quite rare to find, making an exact size difficult to pinpoint.
  • Short-Faced Bear: These gigantic bears were quite common in North America up until about 11,000 years ago. They regularly weighed in at around 2,000 pounds and when standing upright reached heights up to 10-12 feet. Unlike today's bears who can eat plants, these bears were highly carnivorous and would need up to 35 lbs of meat a day to satiate their appetite.
  • Megalodon: This shark is regarded as one of the most powerful predators to ever live as it regularly came in sizes up to 59 ft long. Though compared to the great white, the feeding practice of each is thought to be quite different. The current Great White is known to attack its prey from underneath while the megalodon is speculated to use its powerful jaws to bite through the chest and destroy the heart of its prey.
  • Phorusrhacidae (or Terror Bird): Although these birds were flightless, they were the apex predator in South America about Cenozoic era (66 million years ago). They came in at 4-10 feet tall and could strike with terrifying speed and power. The large, oversized beak acted like a sledgehammer. If that weren't bad enough, these birds were very nimble and could sprint up to 30 mph.
