While we all hate being bitten by mosquitos, their bite can actually be deadly. These minuscule pests cause 2 to 3 million deaths every year and spread diseases to 700 million people.
They take host to a variety of mammals, birds, reptiles, amphibians, and even some fish. They are found in all different climates, including warm, humid tropical regions and cold regions. There is literally no getting away, though a mosquito repellent should do the trick. And as long as you are not allergic, you will probably survive a sting.
Death Adder
You definitely want to avoid stepping on one of these if you’re in a bushy area in Australia, Papua New Guinea, or nearby islands. While other snakes will slither away at the presence of a threat, the Death Adder freezes.
Their long fangs can deeply penetrate your skin and inject an average of 40-100 mg of highly toxic venom with one bite. Their bite can lead to paralysis and, ultimately, to a complete respiratory shut-down within six hours.
Bull Shark
Found worldwide among warm, shallow waters along coasts and rivers, is one of the most dangerous and aggressive species of sharks, even more so than the great white.
Also known as the Zambezi shark, the bull shark is a determined predator and rarely fears being attacked by other animals. Humans pose the biggest threat to them, but that still doesn't mean you want a one-on-one meeting with any of them.
Southern Cassowary
Related to the ostrich and emu, this flightless bird is the most dangerous land bird. One of the many flightless birds native to New Zealand, it is miles away from the docile kiwi in terms of aggression.
Known as the deadliest bird in the world, the cassowary has powerful legs with sharp talons that they use as their most powerful weapon. They can charge, kick, and claw you to death. Basically, you don’t want to be face-to-face with one.
Giant Asian Hornet
Also known as the yak killer, this is one of the most dangerous Japanese hornets and the world’s largest one. It is native to temperate and tropical Eastern Asia and lives mostly in low mountains and forests.
They are characterized by their light orange head, brown antennae, and yellow-orange base. Their stinger injects a very potent venom that can cause severe tissue damage. They are responsible for 30-40 human deaths every year in Japan.
