We're accustomed to thinking, probably also due to movies and the stories we're told, that the most lethal animals on the planet are the shark, the lion, or the tiger. Sure, the latter are far from harmless, but compared to other species no one would ever suspect, they're responsible for the deaths of fewer than 100 people a year. After all, you just need to keep well away. Although it's not always that simple.

The top 10 includes creatures beyond imagination and even animals we know quite well.

Zanzare

The undisputed queen is indeed this insect. It is the insect that causes the greatest number of deaths in both humans and animals in general. Estimates stand at around 750.000 deaths per year. This happens for one reason in particular: they are the main sources of transmission of deadly diseases.

Some of the worst epidemics have been triggered by these insects, apparently harmless and merely annoying. But in reality they are capable of decimating the population by spreading diseases such as malaria, typhus, The yellow fever, The dengue, The Nile disease , Zika disease.

Tsetse Fly

It is a small fly that lives on the African continent, more specifically in the sub-Saharan area. This small insect is responsible for the transmission of a sneaky disease like that of sleeping sickness.

Most of those bitten show symptoms of anxiety, heavy sweating, heart problems, high fever, and often end in death.

Hippopotamus

Native to the Horn of Africa, this colossus of the animal kingdom is still among the most fearsome creatures around. It's responsible for the deaths of around 500 people every year. But it also has an extraordinary weapon: the strength of its jaw. On average, it has a total pressure of about 800 kilos of force in a single bite.

Coccodrillo

The oldest reptile on the planet is also the most lethal in both the sea and freshwater. With a grip that is about five times greater than that of the hippopotamus, crocodiles boast the most powerful bite in the animal kingdomThe primacy goes to Nile crocodile with a bite force of 5.000 psi. Furthermore, with shielding armor, they camouflage themselves in the water and can wait for hours, motionless, without a hint of movement, before lunging and grabbing their prey. These immense predators also cause the deaths of approximately 1000 people each year.

Blue-ringed octopus

In scientific jargon it is known as Hapalochlaena lunulata. Belonging to the family of cephalopods, octopus The greater blue-ringed mollusk is a mollusc that lives among the Indo-Pacific coral reefsThis marine animal is not aggressive by nature and is often inclined to flee rather than attack. The causes of death recorded for this mollusk are very few in history. Yet, when it does happen, the situation becomes complicated. In fact, the poison released by the octopus has a toxicity equal to 100 times that of cyanide.

Cone snails

You might be fascinated by the sight of these colorful shells on the shore or even among the colorful coral reefs. But it's anything but joking when it comes to the killer snail. A name that alone says a lot about its dangerousness. In fact, these small sea snails, mostly found in the seas of Caraibi, Indonesia e HawaiiThey have poisonous spines. And if left untreated, the poison can be fatal.

Golden frog

On the subject of small animals, let's move on to another tiny, cute-looking creature: the golden frogNative to the Amazon rainforest on the Colombian side, this frog, which grows to 55 mm in length, secretes a venom capable of killing ten humans at once. Living in an area far from hospitals and medical services, a single touch can truly be a death sentence.

Black Mamba

Snakes in general are among the world's most lethal animals, contributing to the deaths of approximately 50 people each year. Among these, there are only a few whose living conditions and dangerousness make them even more fearsome. And the black mamba is rightfully one of the snakes that boasts the gruesome success of being the greatest human killer. To date, it is considered the snake that has caused the most deaths.

Tenie

The last two species are much smaller in size, but cause the deaths of between 2000 and 2500 people each year. Tapeworms live in the intestines of the 10/15 percent of the world's populationEspecially in developing countries. When moving, these animals cause excruciating pain and, if not treated properly as mentioned, can lead to death. Certainly among the most dangerous animals in the world.

Ascaris Lumbricoides

Finally, we conclude with another slimy creature: Ascaris lumbricoides, a green parasite that, like a tapeworm, feeds inside our bodies. This too, if not caught at the right time, can be fatal.

However, it should not be forgotten that the men are responsible for the death of about half a million of other individuals of the same species every year. The constant wars, murders, and reckless—or rather, reckless—choices also lead to an even higher number of animal deaths, many of which are threatened with extinction or already extinct.
