The Jararaca is a venomous pit viper which is mostly found in South America provinces of Brazil, Paraguay, and Northern Argentina. The Jararaca (English and Portuguese name) species derived their name from two Tupi words “yarará” and “ca,” which means ‘large snake.’ The Jararaca prefers dense evergreen habitat and deciduous tropical forests, but it also dwells in semi-tropical upland forest and savannas. There are documented cases of Jararaca bite in rural and urban centers. Victims of Jararaca bite experiences bleeding, swelling, and in severe cases, death due to shock.
Vipers are a large family of reptiles found all over the world, with the exceptions of Australia, New Zealand, Madagascar, Antarctica and Island clusters such as Hawaii. All vipers and venomous and they have long hinged fangs. Vipers hunt and eat small rodents, which they envenomate with deadly paralyzing neurotoxins. Sometimes, vipers extend their fangs without releasing venom to deliver a ‘dry bite’ to human victims, so they don’t deplete their venom reserve.
23. Western Green Mamba
The Western Green Mamba is a nervous but extraordinarily agile and alert snake that lives mainly in the tropical rain forest, thickets and woodland regions. The Western Green Mamba has a terrible bite that can kill several humans within a short time if victims are not treated on time.

The Eastern Green Mamba is highly venomous like all other mambas. A bite contains enough venom to kill several people. Eastern Green Mambas are slender, alert and persistently arboreal to keep with their velvety, bright green color. They may gape and hiss but are less likely to do so than black mambas. Symptoms of Eastern Green Mamba bite often progress from respiratory paralysis to cardiac arrest and in some cases, death.
21. Many-Banded Krait
The Many-Banded Krait is one of the most venomous snakes in Asia. The white and black banding snake moves slowly and hunts on the ground at night but is capable of an aggressive strike if rattled. Edward Blyth was the first scientist to describe the Many-Banded Krait snake in 1861. The snake tends to be docile and is quick to flee if surprised. But it can also attack and strike from multiple directions swiftly with venom potent enough to kill up to a two dozen men.
20. Bothrops Asper
The Bothrops Asper is more of a nocturnal reptile found in lowland habitats which are often near human dwellings. A likely reason the snake is considered deadly is its dwelling proximity to humans. Bothrops Asper is responsible for nearly fifty percent of snakebites in Costa Rica. The reptile is an irritable and fast-moving snake that humans would do all to avoid staying close to it!
19. Russell’s Viper
The Russell’s viper is one of the most deadly snakes in Asia, and it is responsible for thousands of deaths annually in the continent.

15. Eyelash Viper
The Eyelash Viper is an ambush predator that waits patiently for unsuspicious prey to wander its way. Sometimes, the snake can select a specific ambush area and return to it during the spring migration of birds every year. Eyelash Vipers keep improving their strike accuracy over time. There are South American villagers that believe that the snake winks and flashes its eyelashes at its victims after a deadly strike.
The Boomslang belong to the Colubridae family. They are mostly harmless to humans due to their ineffective fangs and small venom glands. However, the Boomslang is unique among the family because it has large fangs at the back of its jaw with which it delivers its extremely potent venom.

Venom from this species results in internal and external bleeding, which may kill a victim within a short period.
13. Coral Snake
A single bite from this species may not cause much harm since a victim experiences no pain or swelling at first.

In Africa, Southwest Asia, and Arabia where it is found, it accounts for a higher number of human deaths than all other snakes combined.
Rattlesnakes are concentrated in Northern Mexico and Southwest of United States. It is known that more than 13,000 species of this snake is found in Arizona alone. Although its bite is less fatal if victims are given proper and prompt medical attention.

5. Eastern Brown Snake
Native to Indonesia, Australia, and Papua of Guinea, this snake is known to have spread its terror to humans. Following the LD50 value in mice, it is considered the second most poisonous land snakes globally. LD50 value is the measure of a snake's lethal dosage of venom.
4. Death Adder
Among snakes found in Australia, the death adder, which is native to Australia, is likely the most poisonous. One unique thing with this snake is that it waits patiently (usually for days) for its prey. It camouflages well with leaves and swiftly attacks its prey. After injecting its poison, it awaits the death of its victim before it begins eating it.
3. Philippine Cobra
Among toxicology experts, the Philippine cobra is presumed to be the deadliest going by the toxicity of its venom. Usually, it takes a maximum of 30 minutes for anyone who suffers this snake to die. According to experts, its venom is able to interrupt nerve signal transmission, thereby collapsing the respiratory system in no time. For this reason, it is considered one of the deadliest of snakes in the world.

1. Belcher’s Sea Snake
Experts say that the venom from the Belcher's sea snake is up to a hundred times more than that from other snakes. Do you know that while a single drop of the King Cobra's venom is enough to kill more than 150 persons, just a few milligrams venom from the Belcher's sea snake is capable of killing more than 1,000 persons? However, the snake hardly bites because it is very timid.
