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

It lives in forests, grasslands and sparsely forested areas, and is common in places disturbed by people. It hides during the day in palm crowns, hollow logs, rock crevices, caves and the dark corners of thatched houses near the roof. In Darwin, Australia, it is most often met in suburban areas during the wet season from January to March.1

  • Some individuals have red, saddle-shaped blotches1
  • Vertical pupils, like a cat's eyes1
  • Active at night, and usually found in trees1

Lakas ng kamandag

Mga kagat

Lumalabas ang kamandag sa pangil o ngipin nito kapag nangangagat ito.

Ano ang epekto ng kamandag nito?

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

Gaano ito kapanganib sa tao?

Panganib sa tao: MasakitTalagang masakit, pero halos hindi kailanman malala.

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

Ano ang ginagawa nito kapag natatakot?

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

Kung kumagat ito

  • Hugasan ang kagat, panatilihing kalmado ang tao at kumuha ng tulong medikal. May mga species (gaya ng boomslang) na puwedeng nakamamatay makalipas ang ilang oras.

Laging tawagan muna ang numero pang-emergency (112, 000, 911). Ito ay pangkalahatang gabay sa pangunang lunas, hindi payong medikal. Mga batayan ng pangunang lunas

Mag-ingat

  • Huwag kailanman hawakan, hulihin o asarin ang ligaw na hayop, kahit maliit, at kahit mukha itong tulog o patay.
  • Bigyan ito ng espasyo. Kung makasalubong ka ng isa, manatiling kalmado, dahan-dahang umatras at hayaan itong umalis.
  • Kung kagatin ka ng isa: manatiling kalmado, huwag gumalaw, tawagan ang numero pang-emergency (112, 000, 911) o pumunta agad sa ospital. Tandaan ang itsura nito, makakatulong ang litrato.

Hindi ka nito hinahabol. Ginagamit nito ang kamandag para manghuli ng pagkain o ipagtanggol ang sarili, at mas gusto pa nitong magtago. Higit pa tungkol sa pag-iingat

Mga fact

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

Myth buster

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

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