Como recoñecelo

  • Adults are light to chocolate brown or yellowish, with no hood marks and no spots on the throat.1
  • Juveniles are pale and faded, with dark and light cross-bands of about equal width around the body.1
  • The hood is long and tapers gradually, unlike the rounder hood of some other cobras.1
  • It has several dark bands under the throat.1
  • It is never fully black, although some individuals can be quite dark.1

Adoita confundirse con: The Caspian cobra is often confused with the Indian cobra, and the two live side by side in Pakistan and northern India. Indian cobras without a hood mark look similar. In the black form of the Indian cobra from Pakistan, almost the whole throat is black, while the Caspian cobra has several dark throat bands and is never fully black.1

Poder da pezoña

Morde

A pezoña sae polos seus cairos ou dentes cando morde.

Que fai a súa pezoña?

Its venom is mainly neurotoxic, meaning it attacks the nerves, and most of the venom is made of short neurotoxins. It also contains cytotoxins, which can kill cells, and enzymes called nucleases, which damage tissue at the bite. Severe pain and swelling appear quickly, and weakness, drowsiness and paralysis of the throat and limbs can appear within an hour. The venom can also affect the heart during the first few hours, and at least one heart attack after a bite has been recorded.1

Que perigoso é para as persoas?

It is regarded as the most dangerous snake in Central Asia and has a high death rate. Between 1979 and 1987, 136 confirmed bites were attributed to it in the former Soviet Union. Of these, 8 people died after receiving antivenom, and 11 of the 15 who did not receive antivenom died. In Iran, it causes more deaths from snakebite than any other snake in the country. Without treatment, death can come in as little as 45 minutes or be delayed for up to 24 hours.1

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

Que fai cando ten medo?

It tends to avoid people, but when cornered or provoked it spreads its hood, hisses, sways from side to side and strikes repeatedly.1

Se morde

  • Medical treatment with antivenom is essential, because untreated bites are often fatal. Symptoms can worsen rapidly without treatment, so urgent medical care is needed.1
  • Mantén a persoa quieta e tranquila, quítalle aneis e cousas apertadas e vai rápido a un hospital: o tratamento é o antiveleno.

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
