World's Most Dangerous Snakes

By Anders Nielsen, Ph.d.

Snake bites are becoming an increasing concern in places where drought and other environmental disturbances force species living in inhospitable regions to migrate towards more hospitable areas. Unfortunately, people prefer coastal areas, which are hospitable to snakes and rather impervious to the effects of global warming, such as abrupt reductions in precipitation frequency.

Humans and snakes live closer and closer together

Species, such as the inland taipan, or the rattlesnake, are not the types of snakes people want in their gardens.

Climate change in the USA has just begun to show its face in Texas, Arizona, California, New Mexico, and Oklahoma. In these southern states, rattlesnakes are the most dangerous species, and the frequency of bites from these creatures is increasing.

Australia is home of the deadliest snakes on the planet earth

In Sri Lanka, the most dangerous snake is the common krait. The fatality rate for common krait envenomation is approximately 6 percent. Common kraits are responsible for more fatalities than the cobra snake in both Sri Lanka and Pakistan.

The 10 Most Venomous Snakes

This is a list of the most venomous snakes on the earth listed from 10 to 1 by LD50 (abbreviation for "Lethal Dose, 50%"). The snakes that you will see in this video are the Australian copperhead, gwardar, death adder, Chappell Island black tiger snake, beaked sea snake, black tiger snake, tiger snake, coastal taipan, Eastern brown snake, and inland taipan.

Pretending to Be a Dangerous Snake

In this video you will see a non-dangerous egg eater snake eating a big egg and ejecting the shells. See how it intimidates an elephant and how it proves scary to an inexperienced baboon.

Factbox snake bites

The most dangerous snake in Africa is probably the black mamba snake. In African countries where the population density is high—countries like Egypt, Ethiopia, South Africa, and Tanzania—the black mamba is in people's mindsas a snake to avoid.

In Brazil it is mainly the bushmaster that Brazilians fear. However, there are a number of other extremely dangerous snakes, including several species of coral snakes and tropical rattlesnakes. If LD50’s numbers for experiments with poison infused subcutaneously is the criteria for dangerousness, the most venomous snakes are below.

The most dangerous snake in the world is the:

Inland Taipan Snake

This snake lives in dry, semi-arid regions of Central Australia.

The taipan is an apprehensive snake that avoids interactions with humans. The effect of envenomation is respiratory paralysis causing suffocation in approximately 45 minutes. The inland taipan is also known as the fierce snake because of its swiftness.

The second most venomous snake in the world is the:

Eastern Brown Snake

The Eastern brown snake, or the brown snake, is endemic of Eastern Australia. As Eastern Australia is a coastline with a high population density, numerous fatalities from brown snake bites materialize annually. Brown snakes can reach a length of 5 feet, and their coloration is variable.

The third most poisonous snake or venomous snake in the world is:

Dubois's Sea Snake

This snake, the highly venomous Dubois snake, is found across the coastline of Northern Australia. It is a sea snake that forages in water.

The fourth most poisonous snake or venomous snake in the world is the:

Yellowbelly Sea Snake

This snake is native to the Indian and Pacific Oceans. It requires a water temperature of a minimum of 16-18 degrees Celsius. They are shorter than two feet.

The fifth most poisonous snake or venomous snake in the world is the:

Horned Sea Snake

Another sea snake, the horned sea snake is found in Northern Australia and in Southern New Guinea. It has scales resembling horns that surround its eyes, giving it its nickname: eyelash snake. It reaches a length of approximately 40 inches.

The nineteenth most venomous snake in the world is the:

Black Mamba Snake

Although this snake is only the 19th most poisonous snake in the world according to the LD50-value criteria, the black mamba snake is in fact one of the most dangerous snakes in the world.

The black mamba is moderately abundant in many sub-regions of Africa. Secondly, they inhabit a wide variety of habitats, including those close to humans. Thirdly, they are known to be aggressive.

They always defend themselves if threatened, and they are agile defenders. Many bites result in fatalities when antivenin is inaccessible. The name black mamba is a bit confusing, as it is a grey snake with a black mouth.
