Russel Viper
The Russell’s Viper is another deadly snake to avoid. What makes it more dangerous than the other types of snakes is that it thrives in open fields and bushy areas, or the places where people live because of its strong attraction to rodents. Some of the common victims of the Russell’s Viper would be outdoor workers. This snake is commonly found in India, Thailand, and Burma. In Burma alone, it accounts for 90% of snakebite deaths. Some effects of its snakebite include extensive bleeding, necrosis, swelling, pain, and vomiting. It can kill you through cardiac, respiratory, or kidney failure. Unfortunately, there is no anti-venom for its snakebite as its venom’s properties are different, depending on the area where the snake is found. It has a deadly venom toxicity with an LD50 of 0.03.
Sea Snake
Black Mamba – (Dendroaspis Polylepis)
The black mamba is a big, black, long, quick, and deadly type of snake. It is recorded as the world’s fastest snake and the second longest venomous snake. Its can move at the speed of 14 miles per hour and it has an average length of 8.2 feet. The effect of the black mamba’s snakebite can be felt in 30 minutes to an hour. It can mean death by heart attack or respiratory failure. Fortunately, an anti-venom has already been created to prevent deaths from the black mamba’s snakebite. Its venom has a 0.05 LD50.
King Cobra
It seems unfairly menacing that a snake that can literally "stand up" and look a full-grown person in the eye would also be among the most venomous on the planet, but that describes the famous king cobra.
King cobras can reach 18 feet (5.5 meters) in length, making them the longest of all venomous snakes. When confronted, they can raise up to one-third of their bodies straight off the ground and still move forward to attack. They will also flare out their iconic hoods and emit a bone-chilling hiss that sounds almost like a growling dog.
Their venom is not the most potent among venomous snakes, but the amount of neurotoxin they can deliver in a single bite—up to two-tenths of a fluid ounce (seven milliliters)—is enough to kill 20 people, or even an elephant. Fortunately, king cobras are shy and will avoid humans whenever possible, but they are fiercely aggressive when cornered.
King cobras live mainly in the rain forests and plains of India, southern China, and Southeast Asia, and their coloring can vary greatly from region to region. They are comfortable in the trees, on land, and in water, feeding mainly on other snakes, venomous and nonvenomous. They will also eat lizards, eggs, and small mammals.
They are the only snakes in the world that build nests for their eggs, which they guard ferociously until the hatchlings emerge.
King cobras may be best known as the species of choice for the snake charmers of South Asia. Although cobras can hear, they are actually deaf to ambient noises, sensing ground vibrations instead. The charmer's flute entices the cobra by its shape and movement, not by the music it emits.
Taipan
The taipan is also called a fierce snake due to the fierceness of its venom. Contrary to its alternate name, the taipan is actually reclusive and shy. After biting its prey, it would normally retreat first to wait for its prey to die before returning to feed on it. It is recorded as the world’s most venomous land snake. The taipan is normally found in Australia. Its venom clots the blood and blocks blood vessels. While an anti-venom has been invented, the recovery period from a taipan’s snakebite can still be painful and slow. Its venom’s toxicity can range from an LD50 of 0.03 to as low as 0.01.
