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

Amandla etyhefu yokuluma nokuhlaba

Ukuluma

Ityhefu iphuma ngamazinyo aso etyhefu okanye ngamazinyo aso xa siluma.

Ityhefu yaso yokuluma okanye yokuhlaba yenza ntoni?

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

Siyingozi kangakanani ebantwini?

Ingozi ebantwini: KubuhlunguKunokuba buhlungu ngokwenene, kodwa phantse akusoze kube kubi kakhulu.

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

Senza ntoni xa soyika?

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

Ukuba siyaluma

  • Hlamba indawo elunyiweyo, gcina umntu ezolile kwaye ufumane uncedo lwezonyango. Ezinye iintlobo (njenge-boomslang) zinokubulala kwiiyure ezininzi kamva.

Soloko utsalela inombolo kaxakeka kuqala (112, 000, 911). Esi sisikhokelo soncedo lokuqala ngokubanzi, asilocebiso lwezonyango. Iziseko zoncedo lokuqala

Hlala ukhuselekile

  • Ungaze uchukumise, ubambe okanye uqhule isilwanyana sasendle, nokuba sincinci, kwaye nokuba sibonakala silele okanye sifile.
  • Sinike indawo. Ukuba udibana naso, hlala uzolile, buyela umva kancinci kwaye usiyeke sihambe ngendlela yaso.
  • Ukuba siyakuluma: hlala uzolile, musa ukushukuma, tsalela inombolo kaxakeka (112, 000, 911) okanye uye esibhedlele ngokukhawuleza. Khumbula ukuba sasikhangeleka njani, ifoto iyanceda.

Asikuzingeli. Sisebenzisa ityhefu yaso ukubamba ukutya okanye ukuzikhusela, kwaye singakhetha ukuzimela. Okungakumbi malunga nokuhlala ukhuselekile

Iinyaniso

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

Umqhekezi weentsomi

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

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