In this post, I will show you which are the 6 most dangerous animals in the world so that if you come across these dangerous animals you can identify them and get away from them. I will divide them into 6 types (bird, lizard, snake, mammal, insect, and marine animal).
- The most dangerous bird
- The most dangerous alligator
- The most dangerous snake
- The most dangerous mammal
- The most dangerous insect
- The most dangerous octopus
Bird
The most dangerous bird in the world is the cassowary. This bird weighs up to 54 kg and can reach a height of 1.8 meters tall. It is not capable of flying, however it can reach up to 50 km/h and jump up to 2 meters.
It is very aggressive and with its claws and kicks it has already killed several human beings, including its owners. The claws of this animal usually have up to 12 cm.
It has a very exotic appearance with beautiful plumage and a hard case on its head that helps it defend itself and make its way through the dense vegetation of its habitat. Due to his helmet and claws, he reminds many people of dinosaurs, especially velociraptors.
A curiosity about this bird is that despite being so dangerous, it was discovered that these animals were created by humans in the Pleistocene period. Lives in New Guinea and Australia. They usually feed on fruits, small animals and fungi.
Alligator
The most dangerous lizard in the world is the komodo dragon. It is also the largest lizard in the world with a size that varies between 2 to 3 meters. This animal normally weighs 70 kg, but can weigh up to 135 kg.
This specimen is at risk of extinction. When adults, they can eat even their own species, especially the smallest.
They can eat up to 80% of their own weight in a single sitting and have a very slow metabolism that would allow them to eat only one food intake per month. They run very fast, reaching up to 20 km/h.
This animal has a great sense of smell, with its tongue it takes air samples and analyzes them with the inside of its mouth. Thanks to their bipartite tongue they can identify if the prey is approaching from one side or the other.
For example: if the right tip of the tongue has a higher concentration, then the prey is in this direction. They also have very good vision that is capable of seeing up to 300 meters away.
A curiosity about komodo dragons is that they are immune to the venom of their own species, being one of the few venomous lizards on the planet. If the animal manages to escape the wounds caused by this predator, once the prey dies from the poison, the komodo dragon will be able to track it down.
Snake
The most dangerous snake in the world is the king cobra (Ophiophagus hannah). This snake usually measures 3 meters and can reach up to 5.5 meters. The average weight of this snake is 6 kg. It has a very painful deadly poison that causes cardiorespiratory arrest in its victims. There is an antidote to the king cobra's venom, but still the victim suffers with various side effects such as heart damage, infections, and kidney failure. It usually feeds on other snakes.
When threatened, she pulls the hood off her face. This structure is not only made up of skin, but also of muscles and ribs that allow it to move and flex. The goal is to put fear in its predators by appearing to be taller and more dangerous, it also stands up and whistles.
A very curious fact about this animal is that it can go months and even years without eating or drinking, the skin on its belly is capable of absorbing water from the ground just by passing through humid areas. It makes a nest to lay its young, being the only snake that builds a nest. The mongoose is the largest predator of this snake, since it is immune to the venom of many snakes.
Mammal
The honey badger (Mellivora capensis) is considered the most aggressive mammal in the world. This animal has very powerful and sharp claws. The skin of this animal also has a very important role when we talk about its protection and it is not because of its resistance, what happens is that its skin is so long that even if you catch it, it manages to turn around with its body and defend itself.
Thanks to its attack and defense abilities, it can feed on a wide range of animals and even eat its own young, it is estimated that only half of them are capable of reaching adulthood. The honey badger measures 30 cm in height and 85 cm in length. Males usually weigh around 14 kg and females usually do not exceed 9 kg.
It is widely found in Africa and Asia, inhabiting forest areas or even deserts. Physiologically how has yet to be discovered, but this animal is immune to a wide variety of snake venoms. A curiosity about this animal is that in 2002 it was described as the bravest animal in the world in the Guinness Book of Records. This specimen is solitary and its activity tends to be more frequently nocturnal, but in cold and dry seasons it can present daytime behavior.
Insect
The insect considered the most dangerous in the world is the tsetse fly. This insect is found in the central portion of the African continent. A curiosity is that this animal has existed for 34 million years. They cause sleeping sickness through a protozoan (Trypanosoma brucei gambiense or Trypanosoma brucei rhodesiense), both animals and humans are susceptible to this parasitic infection.
In humans, sleeping sickness initially causes headache, joint pain, and itching, which then progresses to sleep problems, confusion, and numbness. The disease caused by this fly mainly affects the nervous system of the victim and can worsen in a coma. The diagnosis is confirmed with a sample of fluid from the lymph node, blood or cerebrospinal fluid, detecting whether the patient was infected with the protozoan. The treatment is given through effective drugs against Trypanosoma.
Octopus
The blue-ringed octopus is one of the most dangerous marine animals in the world. This octopus is found mainly in Japan and Australia, but with the currents it can also move to other countries. Its color varies from brown to yellow with bright blue and black rings.
Striking characteristics such as the rings of this octopus are usually called aposematism, that is, the animal presents physical characteristics that are very striking to the senses to warn its prey that it has poison, stings, and an unpleasant taste, among others.
It usually feeds on shrimp and crabs, but it can also eat fish. This octopus is small in size, with an average size of 5-10 cm and reaching a maximum of 15 cm. Its weight varies from 25 to 80 grams.
There is as yet no antidote that is effective against the neurotoxins of the blue-ringed octopus. There are assisted life support methods that can keep the victim alive until the body is able to fully expel the poison. The symptoms after its bite are paralysis of breathing, numbness and muscle weakness.
In addition, it also has several chromatophores under its skin that allow it to blend in with its surroundings. There are three structures that are responsible for changing the appearance of this animal: iridophores, chromatophores, and leucophores.
The iridophores are responsible for the intense blue color. The chromatophores are muscles that surround the iridophores and can contract or expand, thus changing the appearance of this octopus in a matter of seconds. Leucophores give lightness and contrast.
