The rhinoceros viper is a large, stout snake with bright colours and two or three horn-like scales on its nose. It lives in forests across West and Central Africa. It is venomous, and its venom is mainly hemotoxic, meaning it attacks the blood and circulation.1

It mainly lives in forested areas and rarely goes into woodland. It hides by day in leaf litter, holes, around fallen trees or tangled tree roots. It is mainly on the ground but can climb into trees and thickets up to 3 m high, and is sometimes found in shallow pools.1

Nola ezagutu

  • Large and stout, with rough, heavily keeled scales1
  • Two or three horn-like scales on the end of the nose, the front pair often long1
  • Series of blue or blue-green oblong markings, each with a lemon-yellow line down the centre, set within black blotches1
  • Dark crimson triangles down the flanks, bordered with green or blue1
  • Top of the head blue or green, with a black arrow mark1

Askotan honekin nahasten da: The name horned puff adder is also used for Bitis caudalis (horned adder), which is a different species. Because of this, names can cause confusion, so the name butterfly viper is preferred.1

Zer egiten du bere pozoiak?

Its venom is mainly hemotoxic, which attacks the circulatory system, destroying tissue and blood vessels and causing internal bleeding. It also has a neurotoxic component, which attacks the nerves. Small doses of the venom can be deadly. In the few detailed reports of human bites, massive swelling was described, which may lead to necrosis (death of tissue).1

Because its range is restricted, few bites have been reported and no statistics are available. In 2003 a man in Dayton, Ohio, who kept one as a pet, was bitten and died.1

Albiste ona: medikuek badute sendagai bat (antipozoia) edo tratamendu bat honetarako.1

Zer egiten du beldurtzen denean?

When approached it often reveals its presence with a very loud hiss, almost a shriek, and it can strike quickly forwards or sideways without coiling first or giving a warning.1

Kosk egiten badu

  • Eutsi pertsona geldi eta lasai, eduki koska jasotako gorputz-adarra bihotzaren mailan, kendu eraztunak eta gauza estuak, eta joan ospitalera azkar.

Deitu beti lehenik zure larrialdi-zenbakira (112, 000, 911). Lehen sorospenei buruzko orientabide orokorra da hau, ez mediku-aholkua. Lehen sorospenen oinarriak

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.
  • Batek kosk egiten badizu: egon lasai, egon geldi, deitu zure larrialdi-zenbakira (112, 000, 911) edo joan ospitalera azkar. Gogoratu nolakoa zen, argazki batek laguntzen du.

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

Datuak

1

Its scales are so rough that they can cut people who handle a snake that is struggling.1

2

Its vivid colours break up its outline in the dappled light of the forest floor, so it is very hard to see.1

3

Its fangs are not large, rarely more than 1.5 cm long, and when not in use they fold up into the roof of its mouth.1

4

Its bright colours fade quickly after it sheds its skin, as silt from its moist habitat builds up on its rough scales.1

5

At least one antivenom, called India Antiserum Africa Polyvalent, protects specifically against bites from this species.1

Mito-hauslea

Mitoa: Its bright colours make it easy to spot in the forest.

Egia: Its colours give it excellent camouflage in the dappled light of the forest floor, which can make it almost invisible.1
