The South American bushmaster is one of the longest vipers in the world, and it is the longest venomous snake in the Western Hemisphere. It lives in the equatorial forests east of the Andes and on the island of Trinidad. Its bite is dangerous, so it is important to know what it looks like.1

Como recoñecelo

  • Its ground colour is yellowish, reddish or grey-brown.1
  • Dark brown or black blotches run along the body, forming inverted triangles on the sides.1
  • Adults are usually 2 to 2.5 m long, and 3 m is not unusual.1
  • The head is broad and clearly separate from the narrow neck.1
  • The tail is short and ends in a spine. When alarmed it vibrates the tail, which makes a loud rustling in undergrowth.1

Adoita confundirse con: It is similar in appearance to rattlesnakes. It has no rattle, so its tail vibration sounds like rustling leaves rather than a rattle.1

Poder da pezoña

Morde

A pezoña sae polos seus cairos ou dentes cando morde.

Que fai a súa pezoña?

Its venom breaks down tissue, stops blood from clotting, and can cause bleeding. It also has effects on the nerves. At the bite there is pain, swelling, bruising, blisters and skin death. Whole-body effects include low blood pressure, dizziness, vision problems, a slow heartbeat, vomiting, diarrhoea and kidney failure.1

Que perigoso é para as persoas?

Perigo para as persoas: Moi perigosoPode matar a unha persoa que non reciba tratamento.

Its bites are often fatal. Lab tests show its venom is weak, but the mortality rate of bite victims is high. In reported cases, a 7-year-old boy in Brazil died about 15 minutes after being bitten, and a 5-year-old child in Mato Grosso went into shock about 30 minutes after a bite and died within 90 minutes.1

Que fai cando ten medo?

Se morde

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
