The brown tree snake is a slender, night-active snake that climbs well and hunts in trees and on the ground. It lives in coastal northern and eastern Australia, eastern Indonesia, Papua New Guinea and nearby islands. It is famous for harming wildlife on the island of Guam, where it was introduced by accident.1

Nguvu ya sumu

Kuumwa

Sumu hutoka kupitia meno yake ya sumu au meno anapouma.

Sumu yake hufanya nini?

It has two small, grooved fangs at the back of the mouth, so venom flows into the bite slowly rather than being injected in one go. The venom is weakly neurotoxic, meaning it affects the nerves, and may also damage cells locally. Its effects are trivial for adults, and it is mainly used to subdue lizards.1

Ana hatari gani kwa watu?

Hatari kwa watu: InaumaInaweza kuuma sana, lakini karibu kamwe si jambo zito.

The snake is considered aggressive when threatened but not dangerous to adult humans. Serious medical consequences have been limited to children, who are more affected because of their low body mass. On Guam, it has caused widespread power outages, pet losses and emotional distress to residents.1

Hufanya nini akiogopa?

When threatened it is highly aggressive, lunging and striking at the attacker repeatedly.1

Akiuma

  • Osha jeraha, mweke mtu mtulivu na utafute msaada wa kitabibu. Baadhi ya spishi (kama boomslang) zinaweza kuua saa kadhaa baadaye.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

  • Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
  • Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
  • Akikuuma: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

Ukweli

1

Snakes on Guam have been seen moving up large smooth cylinders using a method called 'lasso locomotion', which had not been recorded in snakes before. It is tiring, so they move slowly and stop often.1

2

On Guam, where prey is plentiful and there are few predators, the snakes have grown to 3 m, much longer than their typical 1 to 2 m in their native range.1

3

Shortly after World War II, the snake reached Guam by accident, probably as a stowaway in ship cargo or in aircraft landing gear. Its numbers then grew to unprecedented levels.1

4

Trained dogs are used on Guam to find and remove snakes before cargo and transport vessels leave the island.1

5

Female brown tree snakes have been seen performing courtship behaviours normally used by males, such as tongue-flicking and head-jerking.1

6

Brown tree snakes can survive for long periods without food.1

Kuvunja dhana potofu

Dhana potofu: The brown tree snake is a deadly snake that is dangerous to adults.

Ukweli: It is not considered dangerous to adult humans. Its venom is weak and serious effects have mainly been seen in young children.1
