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

Tuis

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

Wat eet dit?

It eats birds, lizards, bats, mice, other small rodents and frogs, as well as many invertebrates and their eggs. It hunts using both sight and chemical cues. Often it wraps its body around its prey like a constrictor to hold it still while it eats.1

Gifkrag

Byte

Gif kom deur sy giftande of tande uit wanneer dit byt.

Wat doen sy gif as dit byt of steek?

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

Hoe gevaarlik is dit vir mense?

Gevaar vir mense: PynlikDit kan regtig seermaak, maar dit is amper nooit ernstig nie.

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

Wat doen dit as dit bang is?

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

As dit byt

Was die byt, hou die persoon kalm en kry mediese hulp. Sommige spesies (soos die boomslang) kan ure later dodelik wees.

Bel altyd eers jou noodnommer (112, 000, 911). Dit is algemene noodhulpraad, nie mediese advies nie. Noodhulp-basiese beginsels

Bly veilig

Moet nooit aan 'n wilde dier raak, dit vang of terg nie, selfs nie 'n kleintjie nie, en selfs nie as dit lyk of dit slaap of dood is nie.
Gee dit spasie. As jy een raakloop, bly kalm, stap stadig terug en laat dit sy eie pad gaan.
As een jou byt: bly kalm, bly stil, bel jou noodnommer (112, 000, 911) of kom vinnig by 'n hospitaal uit. Onthou hoe dit gelyk het, 'n foto help.

Dit is nie uit om jou te kry nie. Dit gebruik sy gif om kos te vang of om homself te beskerm, en kruip baie eerder weg. Meer oor veilig bly

Feite

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

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

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

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

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

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

Mite-breker

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

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