The boomslang is a highly venomous tree snake from Sub-Saharan Africa. It spends most of its time in trees and bushes, though it also hunts and shelters on the ground. Its venom works slowly, so a bite can look harmless at first and still be life-threatening.1

It lives mainly in forests but also in karoo shrubs, savannahs, lowland forests and grasslands. It is an excellent climber and is mostly found in trees, but it often hunts or shelters on the ground and sometimes hides underground in harsh weather.1

Que come?
It eats chameleons, other arboreal lizards, frogs, and occasionally small mammals, birds, and eggs from nests. It swallows its prey whole and will also eat other snakes, including members of its own species.1

Poder da pezoña

Morde

A pezoña sae polos seus cairos ou dentes cando morde.

Que fai a súa pezoña?

Its venom is mainly a haemotoxin, a type of venom that disrupts blood clotting. Many tiny clots form in the blood, causing bleeding in tissues such as muscle and the brain, while the small blood vessels become clogged. Symptoms include headache, nausea, sleepiness and confusion, and can lead to cardiac arrest and unconsciousness. Because the venom is slow-acting, symptoms may not appear until many hours after a bite.1

Que perigoso é para as persoas?

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

Bites can be fatal. Of eight serious envenomations reported between 1919 and 1962, two were lethal. In 1957, a herpetologist died after being bitten by a juvenile. Hatchlings about 45 cm long are already dangerously venomous. Delayed symptoms can lead victims to wrongly believe a bite was a harmless dry bite.1

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

Que fai cando ten medo?

It is timid and usually bites only when people try to handle, catch, chase or kill it. When cornered, it inflates its neck and takes an S-shaped striking pose.1

Se morde

  • Antivenom is available and treatment is needed after a bite. Complete blood transfusions may also be required, especially if more than 24 to 48 hours pass without antivenom. Do not assume a bite is harmless just because no symptoms have appeared.1
  • Lava a mordedura, mantén a persoa tranquila e busca axuda médica. Algunhas especies (como a boomslang) poden ser mortais horas despois.

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

An adult has only 1.6 to 8 mg of venom, but it is thought that 2 to 3 mg could be enough to kill a healthy adult human.1

2

It can open its jaws up to 170 degrees when biting.1

3

Its head is distinctly egg-shaped, and its eyes are exceptionally large.1

4

It often moves its head from side to side to get a better view of objects directly in front of it.1

5

When it is pursued by something too large to eat, it escapes by moving from branch to branch.1

Desmontamitos

Mito: Rear-fanged snakes cannot produce a lethal bite.

Verdade: For a long time many herpetologists believed this, but boomslang bites have caused deaths.1
