Are vipers always poisonous?

The Viperidae (vipers) are a family of snakes found in most parts of the world, except for Antarctica, Australia, Hawaii, Madagascar, and various other isolated islands. They are venomous and have long (relative to non-vipers), hinged fangs that permit deep penetration and injection of their venom.

Only a fraction of these bites are fatal, but toxins in snake venom can trigger serious medical emergencies that occur within hours; they can cause organ failure, uncontrollable bleeding, severe tissue destruction and paralysis that may restrict breathing, according to the World Health Organization (WHO).

The saw-scaled viper (Echis carinatus) may be the deadliest of all snakes, since scientists believe it to be responsible for more human deaths than all other snake species combined. Its venom, however, is lethal in less than 10 percent of untreated victims, but the snake's aggressiveness means it bites early and often.

Vipera berus, also known as the common European adder and the common European viper, is a species of venomous snake in the family Viperidae. The species is extremely widespread and can be found throughout much of Europe, and as far as East Asia.

Fun Facts. Gaboon vipers are venomous. Their bite can be fatal, though they are calm and rarely bite humans. Their fangs can be 2 inches (5 centimeters) long, making them the longest fangs of any venomous snake.

Antivenom is the treatment for serious snake envenomation. The sooner antivenom can be started, the sooner irreversible damage from venom can be stopped.

It might be obvious, but the thing to do if you are bitten by a venomous snake is to get to a hospital quickly and receive an antidote. Many people think that the venom kicks in instantly, but it can take between 20 minutes and 72 hours to die if left untreated.

The saw-scaled viper, Echis carinatus, is considered the deadliest snake in the world, according to Britannica. This type of snake is said to be responsible for "more human deaths than all other snake species combined." The venom of the saw-scaled viper is not as lethal as other snakes, but it is far more aggressive.

Black mamba (Dendroaspis polylepis)

This snake, found in sub-Saharan Africa, is one of the most feared of all. Unlike the relatively docile inland taipan, the black mamba is known to be particularly aggressive. Although it does not seek out humans, when cornered or threatened it will rear up and strike repeatedly.

Bites and Stings

Although viper and pit viper venom composition varies from snake to snake, components can lead to capillary leak, abnormal clotting, inefficient muscle movement, or neurotoxicity. Capillary leak and abnormal clotting can lead to tachycardia, hypotension, or even hemorrhagic shock.

It is likely the bite will be painful, cause swelling, tingling and distress. However as long as the casualty doesn't have an underlying health problem they should be OK.

The horned viper (Vipera ammodytes) is the most dangerous European venomous snake, also the most important snake in Croatia, given the severity of the systemic envenomation it can cause and the outcome of which can be fatal (8).

Dry bites or bites where only a very small amount of venom is injected may cause slight bleeding, pain, and swelling at the bite injury. If a moderate amount of venom was injected, you are more likely to have severe pain, swelling of the whole limb, and general ill feelings, such as nausea, vomiting, and weakness.

It was about midday on a Thursday in January 1998 when Danie Pienaar came face to face with a black mamba and its bite. Danie, now head of Scientific Services in the Kruger National Park, was a student at the time and tracking white rhinos near the Phabeni tributary, south of Pretoriuskop.

The viper is not very aggressive and usually only bites when disturbed. However, you'd have a hard time calling this species a friendly viper; it's a bit of an oxymoron.

If you have noticed that vipers like rattlesnakes, cottonmouths, and water moccasins tend to look angry, it's mostly due to their protruding scales that gives them a furrowed brow. So it's safe to say that if you see a snake that looks mad, you should probably leave.

Ultimately you are going to need antivenom because antivenom is the only definitive treatment for a snake envenomation, but the tips below are designed to help you get to the hospital alive and leave the hospital in one piece.

Symptoms of a pit viper snakebite usually appear within a few minutes to a few hours after a bite and may include: Severe, immediate pain with rapid swelling. Bruising of the skin. Trouble breathing.

The inland taipan (Oxyuranus microlepidotus) is considered the most venomous snake in the world with a murine LD ₅₀ value of 0.025 mg/kg SC. Ernst and Zug et al. 1996 list a value of 0.01 mg/kg SC, which makes it the most venomous snake in the world in their study too. They have an average venom yield of 44 mg.

Rather than non-IgE-mediated immediate hypersensitivity, patients receiving the second treatment of antivenom may develop IgE-mediated immediate hypersensitivity. Once happened, the antivenom treatment should be stopped promptly and anti-allergy treatment should be given immediately.

Caution

Do not slash the wound with a knife. Do not suck out the venom. Do not apply ice or immerse the wound in water. Do not drink alcohol as a pain killer.

Even more impressive, Australia is home to 20 of the 25 most venomous snakes in the world, including all of the top 11. The world's most venomous snake, the inland taipan is found nowhere else on Earth. It is also called the fierce snake, and carries enough venom in a single bite to kill around 250,000 mice.

Many people who survive bites nevertheless suffer from permanent tissue damage caused by venom, leading to disability. Most snake envenomings and fatalities occur in South Asia, Southeast Asia, and sub-Saharan Africa, with India reporting the most snakebite deaths of any country.

Of the bunch, corn snakes are considered the most docile and gentle. They are also known for being easy to handle and easy to feed. They are nocturnal and love to burrow.

Which Country Has the Most Snakes? Brazil has more snake species than any other country in the world. There are over 375 species living in this country, some harmless and some dangerous. Brazil is home to 60% of the South American rainforest, which is a fertile breeding ground for these reptiles.
