The tiger snake is a large, highly venomous snake that lives in southern Australia, including its coastal islands and Tasmania. It gets its name from the black and yellow bands that look like a tiger's stripes, although its colours vary a lot. Its bite can be fatal, so it is one of the snakes that people in Australia are taught to respect and recognise.1

Inicio
Tiger snakes are usually found in coastal regions. They favour wetlands, creeks, dams and other places near watercourses, and in pastoral (farming) areas they shelter near permanent water. They are usually ground-dwelling, but they can swim and climb into trees and buildings.1

Que come?
Tiger snakes use their venom to kill their prey. Island populations have evolved larger heads to cope with large prey animals.1

Como recoñecelo

  • Banded pattern of darker bands that may be strongly contrasting or faint, in colours from pale to very dark.1
  • Base colours of olive, yellow, orange-brown or jet-black, with a light yellow or orange underside.1
  • Some populations have unbanded specimens, so bands alone are not a sure guide.1
  • Typically about 1.2 metres long, with a robust body and a blunt head.1

Adoita confundirse con: Colour is an unreliable way to tell tiger snakes apart, even between their own subspecies. Accurate identification is best done by an expert using a venom test kit or by counting the scales.1

Poder da pezoña

Morde

A pezoña sae polos seus cairos ou dentes cando morde.

Que fai a súa pezoña?

Tiger snake venom contains potent neurotoxins (which attack the nerves), coagulants (which affect blood clotting), haemolysins (which break down blood cells) and myotoxins (which damage muscle). Early symptoms include localised pain in the foot and neck region, tingling, numbness and sweating. Breathing difficulties and paralysis can then follow fairly quickly.1

Que perigoso é para as persoas?

Perigo para as persoas: MortalUn dos animais máis perigosos do mundo.

Tiger snakes accounted for 17% of identified snakebite victims in Australia between 2005 and 2015, with four deaths from 119 confirmed envenomations. They are potentially fatal to humans. Among snakebite deaths in Australia, only the brown snake causes more. A study reported an untreated mortality rate of 40% to 60%.1

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

Que fai cando ten medo?

When threatened, the snake flattens its body and raises its head above the ground in a classic prestrike stance.1

Se morde

  • Use the pressure immobilisation method. Apply broad, thick bandages over the bite, then continue down and back along the limb to the armpit or groin. Immobilise the limb with a splint. Identifying the snake is not necessary in Tasmania, because the same antivenom treats all Tasmanian snakes.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

2

The Chappell Island tiger snake is the giant of the species, averaging over 6 feet (about 1.9 metres) in length.1

3

Tiger snakes can be found swimming, climbing into trees and entering buildings.1

4

5

Tiger snakes are tolerant of low temperatures and may be active on warmer nights.1

Desmontamitos

Mito: You can tell a tiger snake's type from its colour.

Verdade: Colour varies widely between individuals and seasons, so it is an unreliable way to identify a snake. A venom test kit or scale count is more accurate.1
