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

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

Cómo reconocerlo

  • Vertical pupils, like a cat's eyes1
  • Active at night, and usually found in trees1

Poder del veneno

Mordeduras

El veneno sale por sus colmillos o dientes cuando muerde.

¿Qué hace su veneno?

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

¿Qué peligro tiene para las personas?

Peligro para las personas: DolorosoPuede doler de verdad, pero casi nunca es grave.

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

¿Qué hace cuando se asusta?

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

Si muerde

  • Lava la mordedura, mantén tranquila a la persona y busca ayuda médica. Algunas especies (como la boomslang) pueden ser mortales horas después.

Llama siempre primero a tu número de emergencias (112, 000, 911). Esto son pautas generales de primeros auxilios, no consejo médico. Primeros auxilios básicos

Mantente a salvo

  • Nunca toques, atrapes ni molestes a un animal salvaje, aunque sea pequeño y aunque parezca dormido o muerto.
  • Déjale espacio. Si te encuentras uno, mantén la calma, retrocede despacio y deja que siga su camino.
  • Si te muerde: mantén la calma, no te muevas, llama a tu número de emergencias (112, 000, 911) o ve rápido a un hospital. Recuerda cómo era, una foto ayuda.

Datos

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

Cazamitos

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

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