The northern brown snake is a fast, highly venomous snake found across the north of Australia. It lives in dry country, woodlands and grasslands, and sometimes near towns. It matters because its bite can be deadly, so it is important to know what it looks like and to keep your distance.1

Poder del verí

Mossegades

El verí surt pels ullals o les dents quan mossega.

Què fa el seu verí?

Its venom contains neurotoxins, which attack the nerves, nephrotoxins, which damage the kidneys, and a procoagulant, which affects blood clotting. Although its venom is not the most toxic in the brown snake genus, each bite can deliver a relatively large amount, so it has a high potential to cause a deadly bite. Human symptoms include headache, nausea or vomiting, abdominal pain, severe coagulopathy (serious blood clotting problems) and sometimes kidney damage.1

Com de perillós és per a les persones?

Perill per a les persones: Molt perillósPot matar una persona que no rep tractament.

The northern brown snake has a high potential to deliver a deadly bite. The bite is usually painless and is difficult to see because the fangs are small, so a bite can go unnoticed. In dogs and cats, paralysis is also likely to occur.1

Què fa quan té por?

It usually prefers to retreat from danger, but it is very aggressive when disturbed or threatened and will defend itself if cornered.1

Si mossega

Immobilització amb pressió: embolica amb una bena elàstica ferma la mossegada i després tota l'extremitat, posa-hi una fèrula i mantén la persona completament quieta fins que arribi l'ajuda.
No rentis la mossegada: a l'hospital poden analitzar el verí que queda a la pell per triar l'antiverí correcte.

Estigues segur

No toquis, atrapis ni molestis mai un animal salvatge, encara que sigui petit i encara que sembli adormit o mort.
Deixa-li espai. Si en trobes un, mantén la calma, recula a poc a poc i deixa que segueixi el seu camí.
Si te'n mossega un: mantén la calma, no et moguis, truca al número d'emergències (112, 000, 911) o ves de pressa a un hospital. Recorda com era, una foto ajuda.
