Is Matilda’s horned viper venomous?

He said that, while many people fear snakes, most are harmless and help keep rodent numbers down. Matilda's horned viper can grow to 65cm or bigger, he said, adding: "This particular animal looks fierce and probably is venomous," Davenport, a Briton who has lived in Tanzania for 12 years, told the Associated Press.

Venom yields vary, with ranges of 19–27 mg to 100 mg of dried venom being reported. For venom toxicity, Brown (1973) gives LD ₅₀ values of 0.4 mg/kg IV and 3.0 mg/kg SC. An estimated lethal dose for humans is 40–50 mg.

The horned viper injects its venom into its prey through hollow teeth. The venom causes problems with blood clotting, in particular. In rare cases, a viper bite can be fatal to humans.

After extensive surveys WCS believes the snake survives only in a small degraded forest habitat in Tanzania's Southern Highlands. The total range is much less than 100 sq kms and the habitat is still in decline, meaning the species is critically endangered.

Sahara horned vipers are known to have only a few natural enemies, including honey badgers, monitor lizards, and a variety of wild and feral cat species.

In venom glands, adult specimens of horned viper have 10-45 mg of venom, and one bite can excrete as much as 20 mg of venom, which can be a lethal dose for a healthy adult, especially children, and chronically ill patients.

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.

Antivenom Therapy is the mainstay of treatment for Rhinoceros Horned Viper envenomation. Many of the signs and symptoms are ameliorated or entirely eliminated by the antivenom alone. Other symptoms will require additional therapeutic modalities in order to be corrected.

Despite their reputation, Nose-horned vipers are not aggressive and tend not to bite without considerable provocation. If surprised, wild specimens may react in a number of different ways. Some remain motionless and hiss loudly, some hiss and then flee, while still others will attempt to bite immediately.

Matilda's Horned Viper was found in a remote montane forest fragment in Tanzania's South West.

Cerastes cerastes is generally distributed all across North Africa, including southwestern Arabia and southwestern Israel. Common in the Sahara desert, it is most frequently found between Egypt and Morocco. Its range extends to southward to northern Mali, Niger, northern Chad, Sudan, and Mauritania.

The European common adder, or European viper (V. berus), a serpent often mentioned in works of literature, is a stout-bodied snake that is widely distributed across Europe and Asia. It even ranges north of the Arctic Circle in Norway. It grows to a maximum length of approximately 85 cm (33…

A sharp upright scale above each eye resembles a horn. The desert horned viper moves swiftly across the loose sand by sidewinding, throwing oblique loops first with its top half and then with its lower half. With its sharp-edged scales it can shuffle into the sand with amazing speed, burying itself up to the eyes.

One of the most distinctive characteristics of the Saharan horned viper is the presence of supraorbital "horns", one over each eye. However, these may be reduced in size or absent. The eyes of this snake are prominent and set on the sides of the head.

Eyebrow horns “could disrupt the outline of a viper's head and possibly also conceal the eyes, allowing them to blend in better with their environment”, he says. On forest floors, nose horns could make viper heads harder to spot among leaves and twigs.

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 horned viper is also known as the horned sand viper and the desert horned viper. The term “horned” is applied because of the scales above the eyes and nose. The features help protect the eyes from sand.

What is the deadliest snake? 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."

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.

Danie Pienaar, who was at various times from at least 2009 to 2017 head of South African National Parks Scientific Services and acting managing executive, survived the bite of a black mamba without antivenom in 1998.

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.

Though some are dry bites, which aren't as dangerous and will likely cause some swelling, others are venomous bites, which, if not treated carefully and quickly, can result in death. Always seek immediate medical attention if you've been bitten by a snake, as it could be a matter of life and death.

The hedgehog (Erinaceidae), the mongoose (Herpestidae), the honey badger (Mellivora capensis) and the opossum are known to be immune to a dose of snake venom.

Caution

• Don't use a tourniquet or apply ice.
• Don't cut the bite or try to remove the venom.
• Don't drink caffeine or alcohol.
• Don't take pain-relieving medicine, such as aspirin, ibuprofen (Advil, Motrin IB, others) or naproxen sodium (Aleve).
• Don't try to catch or trap the snake.
