Most Dangerous Animals In The World

Here is a list of the most dangerous animals in the world:

1. The mosquito

Mosquitoes, tiny flying insects, are often hosts to various parasites and viruses , some of them lethal. Thus, through their bite, they infect and spread diseases such as malaria, dengue or yellow fever, causing the death of 725,000 people a year.

 

2. The snail

Despite their harmless appearance, these small mollusks are responsible for 200,000 deaths annually, due to the transmission of a parasitic disease known as schistosomiasis. The snail infects the water of this parasite that, once it comes into contact with humans, evolves and lays eggs, leading to the development of the disease.

 

3. The snake

The snake injects its venom, which consists mainly of saliva with a specific toxic chemical composition , through the fangs in order to immobilize and kill its prey, being able either to affect only the area located around the bite or reaching to cause serious health problems in the cardiovascular and nervous system and, in the worst cases, death. A total of 94,000 deaths are recorded per year from the bite of this reptile. Of course, not all snakes are poisonous or dangerous for humans.

 

4. The dog

The one considered the best friend of man is, at the same time, the author of the death of 61,000 people annually. This is due to the transmission of the rabies virus , which is spread, in the case of this mammal, through the feeding of contaminated meat, or contact with an infected animal, such as foxes and bats and is transmitted through saliva, being able to affect the human being in case of bite.

 

5. The bed bug

Chagas disease , also known as the silent disease , is transmitted through the bite of the bedbug , which causes 12,000 annual deaths. Unlike other dangerous insects, this disease is not transmitted by the bite but by the intrusion of the parasites present in the insect’s feces into the mucous membranes or human wounds. The symptoms of this disease, in a first phase, usually go unnoticed, however, in more advanced stages it leads to intestinal complications, heart failure and even cardiac arrest.

 

6. The Scorpion

The scorpion has always had a reputation for being very aggressive, however, recent studies indicate that it only stings as a defense mechanism . The sting is carried out by means of a rapid movement of the stinger located in the back part of the tail above its head and, although most of the bites hardly cause symptoms, others can be fatal, being the cause of 3,250 deaths year. In the following article we will explain the difference between scorpion and scorpion and how to act when faced with a sting.

 

7. The tsetse fly

This insect transmits the so-called “sleeping sickness” or trypanosomiasis through its bite. Its main victims are livestock and humans, something that causes some 2,000 deaths annually.

Sleeping sickness causes different symptoms, in a first stage it includes tachycardia, anemia, weight loss and muscle pain, while in a second stage it causes irritability, mood swings and long periods of sleep until the individual falls into a coma and dies.

 

8. The crocodile

The danger of this reptile is that they are wild animals impossible to tame, so any human approach or intrusion into their habitat can lead to an unexpected attack and in the worst cases can be fatal. Currently, this reptile is responsible for about 1,000 deaths a year.

 

9. Elephant

The elephant is the largest land animal in the world, recognized as one of the most intelligent creatures on the planet and this is demonstrated by its ability to learn, play, imitate, express emotions and develop skills. Perhaps a creature of this majesty and character should not be considered dangerous, but the truth is that this species does not tolerate attacks and human destruction and therefore they are responsible for about 300 deaths a year.

 

10. The human being

The human being, despite not having a considerable size, poisonous glands, claws or sharp teeth, is one of the most dangerous creatures on the planet. This ability is due on the one hand to his ingenuity and intellect and on the other to his behavior, which has allowed him to give rise to world wars and bomb entire regions, causing the death of millions of members of his own species year after year.

In addition, this intellect is also reflected in the consecutive modifications and alterations that it makes in its environment, to accommodate its habitat and improve its living conditions, reducing in turn that of other species and positioning it at the top of the nutritional scale.

 

Most dangerous animals in the sea

But the dangers are not only found in the land environment, they are also in the water. These are the most dangerous animals in the sea:

  • The wasp jellyfish : it is the greatest marine danger. With a minimal amount of its venom it is capable of killing a human being. For all this it is at the top of the most poisonous animals in the world.

 

  • Snakes : just as on land, we also find snakes in the sea. Although not all types of sea snakes are poisonous, what are poisonous can be deadly to humans.

 

  • Blue-ringed octopus : they are a family of small octopuses, in fact they rarely exceed 20 centimeters, however, they have a lethal venom for which we still do not know the antidote.

 

Most poisonous animals in the world

1. Black mamba

This is a species of African snake that is distinguished from the others by its speed of attack. When it feels in danger, it can be very violent and deadly poisonous. It even appears several times in various myths of the sub-Saharan tribes, in which it is attributed magical powers of destruction.

It is characterized by having an olive green skin with an average length of almost 2.5 meters . Generally, it is in the southern and eastern hills of the African continent, and is capable of crawling at  20 kilometers per hour . Contrary to popular belief, this snake gets its name from the dark coloration of its jaws.

 

2. Stonefish

With razors under their eyes , stonefish are among the most dangerous animals in the sea. Its distinctive ” lacrimal saber ” can be used at will by the animal, since it can be removed and retracted from its cheeks when needed. In addition to this, the animal has a spiny dorsal fin that protects it from potential predators.

These fish draw their knives as humans approach them with nets in the institution’s captive aquarium. After years of observation, it has been concluded that they use them to defend themselves.

Despite being heavily equipped to protect itself, the stonefish is characterized by being shy . It camouflages itself with the sand of the Caribbean Sea and the Indo-Pacific – hence its name -, making it even more dangerous: most of the people who are victims of  its sting, did not even know that it was there.

 

3. Arrowhead frog

True to its name, this species of frog has been used in various countries in South America  to coat weapons (such as darts and hunting arrows ) with its powerful poison. It is easily recognized by the brilliance of its yellow skin on the back, and the deep blue on the legs. It is only 5 centimeters long , but this does not prevent it from positioning itself as one of the most toxic amphibians in the world.

It is said that, in pre-Hispanic times, the original inhabitants of the Guianas and those who populated the Amazon rubbed the feathers on their spears with the poison of these frogs, to make them even more lethal. However, this has remained a colonial legend , as there is no historical record of it being true.

They are generally found under the canopy of trees in tropical rainforests. By their very nature, they enjoy humid environments , which is why they are commonly found on mossy rocks or near bodies of water. In addition, they are characterized by being very social frogs , which is why they have been seen in pairs or small groups.

 

4. Blue-ringed octopus

The Hapalochlaena lunulata  is distinguished from all marine animals by bright blue rings lining the entire body. In total, it does not measure more than 10 centimeters , but it is one of the  most lethal cephalopod molusks in the animal kingdom. It can be found in the tropical waters of the western Indo-Pacific, generally in  Sri Lanka , the  Philippines , Australia,  and southern  Japan .

The coloration of these marine animals varies according to the environment in which they develop. However, they generally range from mustard yellow to shades of ocher . The color of the skin stands out with the electric blue of the rings, which can measure up to 8 millimeters in diameter .

Unlike other octopuses, this one is not edible. On the contrary, it is highly toxic. Although it has a gentle appearance, the saliva of this animal can cause severe nausea , loss of speech , a blue discoloration of the limbs and bleeding in the human body.

 

5. Golden cone

Also known as Conus textile , its scientific name, this is a marine snail that is characterized by its predatory agility. They typically feed on worms, but some have evolved to feed on small species of fish. However, they stand out from among other mollusks for their shells of fiery colors that, in some cases, reach neon tones .

To paralyze their prey, conical snails have a hypodermic needle-shaped tooth, which is used to inject venom into them. This substance has a remarkable amount of different toxins, which completely petrifies them into a state of hypoglycemic shock.
