Any animal with the word bullet in its name is something you should worry about. This animal’s bite has been compared to a bullet wound and it will make your skin throb, hence the obvious name. Their painful bite will mercilessly leave you pulsating and burning for as long as 24 hours.
They are found in human lowland rainforests in Central America. These ants can measure up to an inch and have sticky feet to allow them to climb anything. Just make sure it doesn’t climb up your leg.
Mediterranean Black Widow
Just by looking at it, you can tell that this spider is ten times more dangerous than the original Black Widow. This arachnid, with its crazy design and large venom glands, is much deadlier than the original Black Widow. You do not want to be by this tiny but very deadly arachnid, especially the female spiders, as their unusually large venom glands are extremely harmful, specifically to humans. You can distinguish the female from its male counterpart by its dark brown or glossy black color with a red/orange hourglass shape on its bellies.
And don’t let its name fool you into feeling sorry for it. Their names come from the practice of females eating males after mating. Males usually select their female partners by sensing chemicals in the web that tell them whether the female has eaten already.
Millipede
The dangerous relative of the centipede, humans luckily don’t have to worry much about this animal. They pose more of a danger to ants and other larger predators by burning through their external skeleton and irritating the predator’s skin and eyes. They do this by excreting poisonous liquid or cyanide gas through their pores.
They are found in all continents except for Antarctica, even in such areas as the Arctic Circle. They usually live in leaf litter, dead wood, or soil and have a preference for humid temperatures. In various cultures, millipedes are associated with special powers — they are used to treat certain illnesses and in business rituals. While they aren’t dangerous to humans, native people in Malaysia do use millipede secretions in poison-tipped arrows… so be aware.
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.
