Stephens' banded snake is a tree-dwelling snake that lives only on the east coast of Australia. It is highly venomous, and its venom affects the blood, so it is one of the snakes that people should give plenty of space. It spends most of its life high in the trees of forests.1

Que come?
It is a nocturnal predator that hunts both by actively searching and by ambush. It often coils among rodent nests in tree hollows and waits for prey to return. It mainly eats frogs, small lizards, bush rats, mice and pygmy possums, and it hunts juveniles because its mouth is too small for adult prey.1

Como recoñecelo

  • Alternating bands of grey or black and dirty-white along the back, with over 40 of each colour from the back of the head to the tip of the tail1
  • A flat, mostly dirty-white belly, with occasional grey splotches towards the head and tail1
  • A dark brown top of the head, with pale blotches or bars along the lips1
  • A slender body with a broadened, arrow-shaped head1
  • Mostly active at night, and often found in tree hollows high in the canopy1

Poder da pezoña

Morde

A pezoña sae polos seus cairos ou dentes cando morde.

Que fai a súa pezoña?

Its venom is procoagulant, meaning it makes blood clot. It contains prothrombinase, which triggers the production of thrombin in the blood, causing tiny clots throughout the body. Symptoms include nausea, headache, abdominal pain, vomiting, diarrhoea and sweating. If left untreated, the clotting leads to excessive bleeding as blood vessels rupture.1

Que perigoso é para as persoas?

Perigo para as persoas: GraveUnha mordedura precisa un médico. As mortes son moi raras.

It is described as a ready biter, and its envenoming is potentially fatal. Only one death has been recorded: an elderly man in his 60s in Kalang, New South Wales, whose rescue was delayed by torrential rain and floods.1

Boas novas: os médicos teñen un medicamento (antiveleno) ou un tratamento para isto.1

Que fai cando ten medo?

It is described as nervous and defensive towards other animals, and it is a ready biter when threatened.1

Se morde

  • Victims have been successfully treated with up to four doses of 3,000 unit tiger snake antivenom. The wounded person must be transported to hospital for medical treatment.1
  • Inmobilización con presión: envolve cunha venda elástica firme a mordedura e despois todo o membro cara arriba, ponlle unha férula e mantén a persoa completamente quieta ata que chegue a axuda.
  • Non laves a mordedura: no hospital poden analizar a pezoña que queda na pel para escoller o antiveleno axeitado.

Chama sempre primeiro ao teu número de emerxencias (112, 000, 911). Isto son consellos xerais de primeiros auxilios, non consello médico. Primeiros auxilios básicos

Mantente a salvo

  • Nunca toques, collas nin molestes un animal salvaxe, aínda que sexa pequeno e aínda que pareza durmido ou morto.
  • Déixalle espazo. Se atopas un, mantén a calma, recúa amodo e déixao ir polo seu camiño.
  • Se un te morde: mantén a calma, non te movas, chama ao teu número de emerxencias (112, 000, 911) ou vai rápido a un hospital. Lembra como era, unha foto axuda.

Non vai a por ti. Usa a súa pezoña para cazar comida ou para defenderse, e prefire con moito agocharse. Máis sobre como estar a salvo
