Most Poisonous Snakes 

The world is full of incredible and exotic animals of all kinds from the most docile to the most dangerous. One of the most interesting both for its beauty and for its dangerousness are snakes. 

There are a wide variety of snake breeds which are abundant in different parts of the world. Each one has different characteristics such as color, size, docility or dangerousness. In this case, we will talk about the most poisonous snakes in the world. We must clarify that although there are other toxic snakes that can be deadly, the ones that we will mention below are considered to be the most powerful venomous bite creatures. 

Most Poisonous Snakes 

Inland Taipan (Oxyuranus microlepidotus) 

This snake belongs to the Oxyuranus family and is known as one of the most poisonous snakes in the world. It inhabits the eastern part of Australia. 

The Inland Taipan presents a coloration of its skin that varies between brown, yellow or olive green. In addition, there are some of them that can even be orange or red. However, it is essential to note that these beautiful snakes tend to change color depending on the season of the year they are in. That means that its color will be darker during the winter seasons and lighter during the summer. 

The Inland Taipan’s head is elongated with an oval snout. The eyes are average in size and are usually brown with black. This snake measures approximately 1.80 cm and has 23 rows of scales along its body, from 55 to 70 subcaudal scales and one anal scale. 

The venom of this animal is the most potent among all other land snakes. This poison consists of taipoxin, which is a mixture of procoagulants, neurotoxins, and myotoxins. The symptoms that can produce in people are headaches, vomiting, nausea, stomach pain, seizures, coma, etc. Of course, they also cause death in an estimated time of 45 minutes. 

Common Krait (Bungarus caeruleus) 

It belongs to the Bungarus family and is the most poisonous of its kind. They are generally docile and shy snakes that tend to appear at night. They almost always hide by coiling under heavy objects such as a rock. 

Depending on the sex, it may have a different size. The average size is almost 1 m long but can grow up to 1.75 m. The body of this snake is cylindrical, its head is flat, its tail is short, and its eyes are small with round pupils. The Common Krait has a bluish-black color and can be identified thanks to its pattern of 40 crossbars throughout its body. 

The venom consists of a lethal neurotoxin being 16 times more potent than that of a cobra. These snakes can cause muscle paralysis, so it is essential that the victim is promptly treated medically. Other symptoms caused are headaches, nervous system problems, suffocation or abdominal pain. We must take into account that the percentage of mortality of bitten people reaches up to 50% due to the fact that there are antidotes that are not usually 100% effective. 

Black Mamba (Dendroaspis polylepis) 

The Black Mamba belongs to the genus Dendroaspis which includes four species of mambas among which is this one. It is known to be the fastest snake and one of the most poisonous in the world. It can be found in Africa. They generally appear during the day, and although sometimes they can be shy, they show aggressiveness when a person approaches their territory. 

The average length of an adult Black Mamba is 2.5m, but they generally grow to over 3m. Some records state that there are some mambas that can grow up to 4.5m. The color of the skin of this animal is dark, generally gray or dark brown. The peculiarity of this snake is that the inside of its mouth, as its name indicates, is black. The head is narrow and elongated, the eyes are medium in size, and its tail is long and thin.

The venom of this dangerous snake is made up of potent neurotoxins and cardiotoxins that usually affect the body of a person or animal in a short time. A single bite of this snake can inject up to 100 mg of venom considering that 15 mg is enough to kill an adult person. 

King Cobra (Ophiophagus hannah) 

It is one of the most dangerous creatures and is considered the longest venomous snake in the world. It may appear in India, South China, Thailand, Vietnam, Indonesia, the Philippines, etc. 

The King Cobra is characterized by its large size reaching up to approximately 5.7 m with a weight that can vary between 6 kg and 12 kg. It should be noted that some have been 6.4 m long. The color of its skin can vary depending on the geographical location in which it is located. They can be brown, yellow, black or green. Its body has excellent flexibility and stability thanks to the large number of vertebrae it has. The head of the King Cobra has a diamond shape that has the hood that these animals usually have. 

Like other snakes, the venom of the King Cobra is mainly composed of neurotoxins, but it can also have other toxic compounds, such as cardiotoxins. A bite from this cobra is enough to kill an elephant in just a few hours. Similarly, a small amount of poison can kill even 20 people who have not been injected with the antidote. Some symptoms are blurred vision, sharp pain, paralysis, coma, respiratory problems, vertigo and later death. 

Generally, they usually attack when they feel threatened or cornered.
