TOP 10 MOST Poisonous Snakes in the World

This is a list of the most venomous snakes in the world that could end the life of people with a bite of venom. These are found in various parts of the world in their natural habitats. One of the most common features of the most poisonous snakes is their shiny, glossy, striking and alluring skins that make them look beautiful and attractive. Another factor about these snakes is that they normally have no intentions of attacking humans. However, when disturbed they turn to be aggressive and venomous.

Venomous Snakes

As the name indicates, this is a family of snakes that uses venom to immobilize their prey. Venom is a chemical substance produced by the snakes through their fangs in times of need. The toxicity of the snakes in this family varies widely depending on the environmental and geographical factors within the snakes environs. It is also important to note that the level of toxicity may also vary even in the same species of snakes hence making it difficult to determine. Though the snakes are considered to be poisonous snakes, it is important to note that in medical terms poison and venom are totally different. While poison must be introduced to the body system through either the skin or the digestive system, venom must be administered to the actual tissues of the body or the blood system. In this regard, here is a list of the top 10 most poisonous snakes in the world.
