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

Cara mengenalinya

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

Kuasa bisa

Gigitan

Bisa keluar melalui taring atau giginya apabila ia menggigit.

Apa kesan bisanya?

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

Berapa bahaya ia kepada manusia?

Bahaya kepada manusia: MenyakitkanIa boleh jadi sangat sakit, tetapi hampir tidak pernah serius.

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

Apa yang ia buat apabila takut?

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

Jika ia menggigit

  • Basuh tempat gigitan, pastikan orang itu tenang dan dapatkan bantuan perubatan. Sesetengah spesies (seperti boomslang) boleh membawa maut beberapa jam kemudian.

Sentiasa hubungi nombor kecemasan dahulu (112, 000, 911). Ini panduan pertolongan cemas umum, bukan nasihat perubatan. Asas pertolongan cemas

Kekal selamat

  • Jangan sesekali sentuh, tangkap atau usik haiwan liar, walaupun yang kecil, dan walaupun ia nampak tidur atau mati.
  • Beri ia ruang. Jika kamu terjumpa, bertenang, undur perlahan-lahan dan biarkan ia pergi.
  • Jika ia menggigit kamu: bertenang, jangan bergerak, hubungi nombor kecemasan (112, 000, 911) atau pergi ke hospital dengan segera. Ingat rupanya, gambar boleh membantu.

Fakta

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

Pemecah mitos

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

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