The puff adder is a large, stout viper that lives across most of Africa and parts of the Arabian Peninsula. It is one of the most dangerous snakes in Africa because it lives in places where many people live and work, and it has very potent venom. Its camouflage hides it well, so it is easy to step near without seeing it.1

Com reconèixer-lo

  • Stout, heavy body. Usually about 1.0 m long including the tail.1
  • Two dark bands across the top of the head, and two dark bars running from each eye down the sides of the head.1
  • Back is straw yellow, light brown, orange or reddish brown, with 18–22 dark brown to black chevron-shaped bands running down the back and tail.1
  • In some populations, the body is heavily flecked with brown and black, giving a dusty-brown or blackish look.1

Poder del verí

Mossegades

El verí surt pels ullals o les dents quan mossega.

Què fa el seu verí?

Its venom is cytotoxic, which means it destroys body tissue. Bites cause severe pain, swelling, bleeding under the skin and, in serious cases, tissue death that can spread and lead to gangrene. Other symptoms include shock, nausea, vomiting, dizziness and periods of semi-consciousness. Death can occur in about 25 hours from a dose of around 100 mg, and deaths usually come 2–4 days after a bite from complications.1

Com de perillós és per a les persones?

Perill per a les persones: MortalUn dels animals més perillosos del món.

It is responsible for more snakebite deaths in Africa than any other African snake. This is due to its wide range, common presence near people, large size, potent venom and aggressive temperament. Deaths are uncommon in untreated cases, but severe bites can be fatal, with one report giving a 52% mortality rate. Most deaths are linked to poor medical care.1

Què fa quan té por?

When disturbed, it hisses loudly and continuously, coils tightly with the front of its body in a taut S shape, and may back away towards cover before striking suddenly and fast.1

Si mossega

  • Mantén la persona quieta i tranquil·la, mantén l'extremitat mossegada a l'altura del cor, treu-li anells i coses que estrenyin i porta-la de pressa a un hospital.

Truca sempre primer al número d'emergències (112, 000, 911). Això són pautes generals de primers auxilis, no consells mèdics. Primers auxilis bàsics

Estigues segur

  • No toquis, atrapis ni molestis mai un animal salvatge, encara que sigui petit i encara que sembli adormit o mort.
  • Deixa-li espai. Si en trobes un, mantén la calma, recula a poc a poc i deixa que segueixi el seu camí.
  • Si te'n mossega un: mantén la calma, no et moguis, truca al número d'emergències (112, 000, 911) o ves de pressa a un hospital. Recorda com era, una foto ajuda.

Dades

1

A female in a Czech zoo gave birth to 156 young, the largest litter recorded for any snake species.1

2

Its fangs are long and can penetrate deeply, and the force of its strike can kill prey by physical trauma alone.1

3

A large adult can produce between 150 and 350 mg of venom at a time, with a maximum of 750 mg.1

4

Dogs and meerkats, which hunt by scent, find it hard to detect because of a form of olfactory crypsis, meaning it hides its scent.1

5

It is one of the most toxic vipers based on LD50 (the dose that kills half of test animals in a study).1

6

It is a good swimmer and climber, and one specimen was found 4.6 m above the ground in a dense tree.1

Desmuntamites
