The pygmy copperhead is a small, venomous snake found only in South Australia, mainly on Kangaroo Island and in the Fleurieu Peninsula and Mount Lofty Ranges. It is the smallest of the Australian copperheads. Its venom is dangerous, so prompt medical treatment matters.1

Inicio
It lives in moist areas near streams, in swamps, marshland, and open sclerophyll woodland and forest, where average yearly rainfall is 600–800 mm. Sightings have also been made in the Adelaide Hills, and on islands near Tasmania, probably after accidentally stowing away on boats.1

Poder da pezoña

Morde

A pezoña sae polos seus cairos ou dentes cando morde.

Que fai a súa pezoña?

The venom is strongly neurotoxic, which means it attacks the nerves, and its toxicity is similar to that of the Indian cobra. It is weakly coagulant and strongly anticoagulant, meaning it can both disrupt blood clotting and destroy blood and muscle. Without prompt treatment, a bite can cause possibly irreversible damage to nerve endings.1

Que perigoso é para as persoas?

Perigo para as persoas: GraveUnha mordedura precisa un médico. As mortes son moi raras.

Bites are considered possibly lethal. The snake is not known for being aggressive and is unlikely to attack unless it is stepped on or purposely provoked.1

Boas novas: os médicos teñen un medicamento (antiveleno) ou un tratamento para isto.1

Que fai cando ten medo?

It is generally unobtrusive and usually hides under leaf litter, old iron and haystacks.1

Se morde

  • Prompt antivenom treatment is essential, because bites are considered lethal without it. Antivenom developed from tiger snake venom cannot completely neutralise the neurotoxicity of pygmy copperhead venom.1
  • Inmobilización con presión: envolve cunha venda elástica firme a mordedura e despois todo o membro cara arriba, ponlle unha férula e mantén a persoa completamente quieta ata que chegue a axuda.
  • Non laves a mordedura: no hospital poden analizar a pezoña que queda na pel para escoller o antiveleno axeitado.

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
