Found in sub-Saharan Africa, these flies carry the sleeping sickness, which can affect humans and be deadly if not diagnosed and treated on time. According to researchers, they are responsible for a whopping 250,000 human deaths a year.
They spread diseases by feeding off the blood of their hosts. They are mostly found in tropical Africa.
African Elephant
While mostly peaceful, the world’s largest animal is naturally bound to be dangerous. They sometimes display bouts of rage and can get aggressive, trampling other animals and destroying villages in their way. They are prevalent in Sub-Saharan Africa in dense forests, woodlands, and deserts.
They are some of the most intelligent species and display a variety of behaviors and emotional capabilities such as grief, learning, play, humor, altruism, compassion, and self-awareness.
Wild Boar
Hunters say that this animal can be even harder to catch than wild bears. With a weight of up to 660 Ibs, this aggressive mammal also comes in fourth in the list of most intelligent animals on the planet. Its sharp tusks are to be avoided at all costs. They are also known to be the host of at least 20 different parasitic worm species, with most infections taking place in the summer.
While attacks on humans are rare, they can be serious and result in injury. The boar attacks by charging and pointing its tusks toward its victim, usually injuring their thigh. After the first attack, they step back to look if the victim is still moving. If so, they keep attacking until the victim is immobile.
Electric Eel
Known as a deadly predator in the waters of the Amazon rainforest, they get their name from their ability to generate a strong electrical charge of up to 600 volts. They're not actually eels, but a member of the “knife-fish” family.
These fish are highly desirable by some animal collectors, but very hard to catch. The only viable way is to exhaust them by making them deplete all of their electricity. Eventually, the fish’s electric organs become discharged and the hunter can swoop in for the kill.
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.
