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

Poder da pezoña

Morde

A pezoña sae polos seus cairos ou dentes cando morde.

Que fai a súa pezoña?

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

Que perigoso é para as persoas?

Perigo para as persoas: MortalUn dos animais máis perigosos do mundo.

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

Que fai cando ten medo?

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

Se morde

  • Mantén a persoa quieta e tranquila, mantén o membro mordido á altura do corazón, quítalle aneis e cousas apertadas e vai rápido a un hospital.

Chama sempre primeiro ao teu número de emerxencias (112, 000, 911). Isto son consellos xerais de primeiros auxilios, non consello médico. Primeiros auxilios básicos

Mantente a salvo

  • Nunca toques, collas nin molestes un animal salvaxe, aínda que sexa pequeno e aínda que pareza durmido ou morto.
  • Déixalle espazo. Se atopas un, mantén a calma, recúa amodo e déixao ir polo seu camiño.
  • Se un te morde: mantén a calma, non te movas, chama ao teu número de emerxencias (112, 000, 911) ou vai rápido a un hospital. Lembra como era, unha foto axuda.

Non vai a por ti. Usa a súa pezoña para cazar comida ou para defenderse, e prefire con moito agocharse. Máis sobre como estar a salvo

Datos

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

Desmontamitos

Mito: Puff adders are fast, aggressive snakes that chase people.

Verdade: They are normally sluggish and rely on camouflage for protection. They strike when disturbed, but they do not usually pursue people.1
