Russell's viper is a highly venomous snake of South Asia. It is one of the "Big Four" venomous snakes of the region, known for a bite that is extremely painful. It often lives close to people because it hunts the rodents found in farms and villages.1

It lives in open grassy or bushy areas, scrub jungle, forest plantations and farmland, mostly on plains, coastal lowlands and hills. It is often found in urbanised areas and villages, where rodents are common, so people working outside in these areas are most at risk of being bitten.1

  • A deep yellow, tan or brown body with three rows of dark brown spots running along its length1
  • Each dark spot has a black ring with a white or yellow rim around it1
  • A pair of dark patches on the temples, and a pinkish, salmon or brownish V or X marking on the head1
  • A flattened, triangular head that is clearly separate from the neck1
  • A stout, rounded body with a short tail, about 14% of total length1

Askotan honekin nahasten da: The rough-scaled sand boa, Eryx conicus, often has a colour pattern similar to Russell's viper. It is completely harmless, so care is still needed with any snake that looks like this.1

Pozoi-ahalmena

Koska

Pozoia letaginetatik edo hortzetatik ateratzen da kosk egiten duenean.

Zer egiten du bere pozoiak?

Its fangs are long and hollow, and it produces a large amount of venom, with adults yielding about 130 to 250 mg in some reports. Bite symptoms begin with severe pain and swelling, followed by bleeding from the gums and in the urine, a drop in blood pressure and a slower heart rate. Blistering can spread along the limb, and kidney failure occurs in about 25 to 30 percent of untreated bites.1

It is known for an extremely painful bite and is one of the "Big Four" venomous snakes of the region. The lethal dose for most humans is about 40 to 70 mg, which is within the amount one bite can deliver. Death can follow 1 to 14 days after the bite, or sometimes later, from infection, kidney failure, breathing failure or heart failure. In one study of people who survived bites, 29% suffered severe damage to the pituitary gland, which later caused hypopituitarism.1

When threatened, it forms a series of S-shaped loops, raises the front third of its body and hisses loudly.1

Kosk egiten badu

  • Early medical treatment and early access to antivenom can prevent severe complications and greatly reduce the chance of a fatal outcome. Seek medical care as soon as possible after any bite.1
  • Eutsi pertsona geldi eta lasai, eduki koska jasotako gorputz-adarra bihotzaren mailan, kendu eraztunak eta gauza estuak, eta joan ospitalera azkar.

Egon seguru

  • Ez ukitu, ez harrapatu eta ez zirikatu inoiz animalia basati bat, txikia izan arren, eta lo edo hilda dagoela badirudi ere.
  • Utzi tartea. Bat aurkitzen baduzu, egon lasai, egin atzera poliki eta utzi bere bidetik joaten.

Ez dabil zure atzetik. Pozoia janaria harrapatzeko edo bere burua babesteko erabiltzen du, eta askoz nahiago du ezkutatu. Seguru egoteari buruz gehiago

Datuak

1

When it strikes, it can exert so much force that large individuals lift off the ground.1

2

Its hiss is said to be louder than that of any other snake.1

3

Adults are usually slow and sluggish and rarely attack unless provoked, but they can strike very quickly.1

4

A harmless sand boa has evolved a colour pattern that looks like this viper, which may help it avoid predators.1

5

The mother can take nearly 4.5 hours to give birth, as one recorded birth of 11 young shows.1

Mito-hauslea

Mitoa: Russell's vipers chase people and bite them.

Egia: They usually do not attack unless provoked. Their threat display of S-shaped loops and hissing has led to the belief that they chase people, but they are strong and may react violently if picked up.1
