There are many dangerous animals on planet Earth, among which snakes stand out most. They are poisonous and dangerous, beautiful, scary and very different in size. They live in all corners of the earth, and meeting with some of them can even end human life.

This reptile species lives on absolutely all continents (including large and small islands), except for Antarctica. Among a large number of species, there is also the poisonous snake krait (photos are attached), about which more detailed information is presented in the article.

List of Earth's most poisonous snakes

  1. The most toxic poison has inland Taipan. About 80 people a year die from his bites, from which even a special serum often does not save. This reptile lives in Australia.
  2. The brown net snake (refers to aspids) is the second most dangerous after the taipan. Harlequin aspid, which lives in the United States, is particularly toxic. After the attack and bite of this snake, a person can die within 24 hours without timely medical assistance.
  3. Black mamba, common in Africa, reaches a length of up to three meters. This aggressive snake attacks at the slightest opportunity and inflicts a bite instantly.
  4. The kraight snake, which lives in Australia and Asia, is aggressive and dangerous to human life. More detailed information about it is given later in the article.
  5. A rattlesnake, which has a wide habitat, differs from its relatives in the special structure of the tail and skull. When a danger occurs, it begins to create a characteristic noise, vibrating the process on the tip of its tail.
  6. Viper common in Asia and Europe. Toxin, depending on the reaction of the human body, acts differently. People can remain disabled after a bite, but there are deaths. The length of the viper is about 50 cm, and the color of the scales can be different, depending on the location of the individual.

Tiger snake, efa sandy, king cobra, hook-nosed sea snake, etc. - all these are dangerous snakes that can kill a person.

Description of the krat kite

The most poisonous and dangerous snakes can look completely harmless, and there are even beautiful ones among them. These include the kraits. This genus has 12 species. The most poisonous among them is the yellow-headed krait. He has small teeth, but in places where people have to wear light clothing, this is a dubious advantage.

The snake has a striped color: transverse and equally thick stripes of white (or any light) and dark blue (or black) shades. On average, the length of a relatively small snake is 1.5-2 meters. The largest species have a length of about 2.5 meters. The head of the poisonous snake kraut is bluntly rounded, the interception of the neck is weak. A slender body ends with an unusual short tail. A keel of larger hexagonal scales passes along the ridge of the snake, in connection with which the body of the kraits in the cross section is obtuse-triangular.

The most common species is pama (tape kraot), which lives in India, Burma and southern China. The most dangerous of this genus is the yellow-headed krait (noted above), which has small teeth, but has the most deadly poison.

Habitats and lifestyle

There are kraight snakes (bungars) in India, on the Andaman Islands, in Sri Lanka, in Pakistan. They live in Southeast Asia (including the islands of the Malay archipelago) and in Australia. They prefer dry places with shelters, and even often there are cases of penetration into people's homes.

They are active mainly at dusk and at night. The diet of snakes includes small mammals, lizards, amphibians and snakes. With a single dose of poison, krait can kill about 10 people. If you ask any reptile specialist to name the ten most dangerous poisonous snakes of the Earth, he will certainly name the kraut. All varieties of this genus are egg-laying. Females guard the clutch until the offspring hatch.

About poison and poisonous apparatus

As noted above, the venomous teeth of kraot snakes are rather short. There are 3 more teeth in the upper jaw behind them, but they are not poisonous.

The venom of this species of snakes has a strong neurotoxic effect, which is associated with the presence of postsynaptic toxins (or α-bungarotoxins) and presynaptic toxins (or β-bungarotoxins) in it. They are absent in the venom of the species Bungarus fasciatus. Tape kraot venom contains cardiotoxin, which is not found in other species.

Apparently, their poison contains a toxic peptide. The latter, when it enters the bloodstream or with the most severe poisoning, has the ability to pass the blood-brain barrier and thus has a direct toxic effect on the brain. In this case, death occurs very quickly without any paralytic symptoms. In addition, the kraot snake venom contains phospholipase A2, dipeptidase and acetylcholinesterase (typical for aspid snakes).

Snakes in Bali

In Indonesia, there are many snakes, among which there are poisonous. Bali is no exception. On this island there are several varieties of poisonous snakes, including one sea and 5 land. Krait kites in Bali (for example, in Canggu) are also found. Among them are marine and terrestrial species. It should be noted that in places with a large amount of green vegetation there is a high probability of meeting this dangerous animal.

Varieties of kraits in these places are black and blue and gray. Their length reaches about one meter. The kraight snake in the ocean is also a fairly common phenomenon. This applies to the striped look. Water kraits (Banded sea krait) are very dangerous snakes in Bali.
