The northern tree-dwelling funnel-web spider is a large spider from eastern Australia. It lives mostly in trees, from South East Queensland to the Hunter River in New South Wales. Its venom can be deadly to people, so it is important to know what it looks like.1

It lives in rotting logs, branches, and hollow furrows and pipes of trees, especially tallowwood, as well as in epiphytes. It has been recorded up to 30 m above the ground. Roving males are found after rain and at night, from late October to early February, and they shelter during the day.1

Kako jo prepoznaš

  • Has a glossy black carapace (the hard upper shell of the body).1
  • Chelicerae (fang-bearing parts), legs and abdomen are matte black or dark brown.1
  • The top of the abdomen may have a plum or purplish tinge.1
  • Body length is 40-50 mm, the largest of the funnel-web subfamily Atracinae.1
  • Cannot jump.1

Pogosto zamenjujejo z: The ground-dwelling Darling Downs funnel-web spider (Hadronyche infensa) is very similar. Male northern tree-dwelling funnel-web spiders have a knobby spur on the tibia (a leg segment) of the second pair of legs, which male Darling Downs funnel-web spiders lack. Trapdoor spiders are browner overall.1

The venom is potentially deadly to humans and is regarded as the most toxic of the venoms in the family Atracidae. Symptoms can start within 15 to 20 minutes. Common symptoms include sweating, high blood pressure, a fast heart rate, muscle spasms, nausea, vomiting, changes in consciousness and pain at the bite site. Fluid in the lungs (pulmonary oedema) is frequent and comes on early.1

Kako nevarna je za ljudi?

Nevarnost za ljudi: Smrtno nevarnaEna najnevarnejših živali na svetu.

The venom is potentially deadly. Of eight recorded bites, five caused severe symptoms of envenomation. Because the spider is larger than the Sydney funnel-web, it may inject more venom, which could make it possibly the deadliest venomous spider in the world per volume of venom.1

Dobra novica: zdravniki imajo za to zdravilo (protistrup) ali zdravljenje.1

Kaj naredi, ko se prestraši?

When threatened, it rears up, displays its fangs, and drops of venom appear on the fang tips.1

Če ugrizne

  • Pressure bandages and immobilising the patient can significantly delay the onset of symptoms. This remains a critical part of managing a bite from an Australian funnel-web spider.1
  • Ugriz umij in ohladi. Poišči zdravniško pomoč, če je bolečina močna ali se poškodovanec slabo počuti.
  • V Avstraliji vsak ugriz velikega črnega pajka obravnavaj kot ugriz lijakastega pajka: Imobilizacija s pritiskom: čvrsto ovij elastični povoj čez ugriz in nato navzgor po celem udu, ud imobiliziraj z opornico in poškodovanca drži popolnoma pri miru, dokler ne pride pomoč.

Vedno najprej pokliči številko za klic v sili (112, 000, 911). To so splošna navodila za prvo pomoč, ne zdravniški nasvet. Osnove prve pomoči

Ostani varen

  • Nikoli se ne dotikaj divje živali, je ne lovi in je ne draži, tudi če je majhna in tudi če je videti, kot da spi ali je mrtva.
  • Pusti ji prostor. Če jo srečaš, ostani miren, počasi stopi nazaj in jo pusti, da gre svojo pot.
  • Če te ugrizne: ostani miren, ne premikaj se, pokliči številko za klic v sili (112, 000, 911) ali hitro pojdi v bolnišnico. Zapomni si, kako je izgledala, fotografija pomaga.

Ne preži nate. Strup uporablja, da ulovi hrano ali se zaščiti, in se veliko raje skrije. Več o varnosti
