These super-aggressive killer bees are known to chase their victims for miles, being much more defensive than other species of bees. They spread throughout the Americas after a Brazilian beekeeper in 1957 was trying to interbreed European and African honey bees and accidentally let some of them loose.
It’s safe to say that these critters are a lot deadlier than their European relatives, and are able to sting victims ten more times. These bees are responsible for the death of around 1,000 humans, horses, and other unfortunate animals.
Blue-Ringed Octopus
This is surely not the octopus you want to see on your dinner plate. It may be the size of a golf ball, but its venom is so poisonous it has the power to kill 26 adults, with no antivenom available anywhere. Within minutes, this creature will leave you unconscious and paralyzed.
They can be found in coral reefs and tide pools in the Pacific and Indian oceans. They are identified by their yellowish skin and blue and black rings that change color when the animal is threatened. They usually live for two years, varying slightly due to nutrition, temperature, and the amount of light available to their habitat.
Tarantula Hawk
A spider wasp that feeds off of tarantulas, the Tarantula Hawk causes dozens of deaths to humans every year. They are one of the largest wasps, growing up to 2 inches long. Their stinger carries a toxin that paralyzes their prey before dragging it (alive) to a nest of eggs and placing a single egg on the prey, which hatches to a larva that eats the living prey.
They can be classified by their vivid coloration of blue-black bodies and bright-colored wings. These colors warn potential predators of their danger. Consider yourself warned… this is not the kind of animal you want to get close to.
Indian Red Scorpion
The deadliest and most lethal of the scorpions, don’t be fooled by the Indian Red Scorpion’s small size. Its venom affects the cardiovascular and pulmonary systems and has a fatality rate of 8-40%. It is especially lethal to children.
It is found in densely populated regions of India, Pakistan, Nepal, and Sri Lanka. When traveling around there, be sure to check your boots before putting them on your feet because these critters oftentimes find their way into shoes.
Ascaris (Lumbricoides) Roundworms
Common in sub-Saharan Africa and tropical climates, these worms infest your body after you drink water that's been contaminated with human feces.
They can cause a serious infection. In fact, they affect around one-sixth of the human population and are widespread mostly in tropical and subtropical climates. There’s a reason you should always drink bottled water in areas with poor sanitation!
