These can include reptiles (such as lizards or geckos), marsupials (such as antechinus and dunnarts), mammals (such as rats) and birds. When funnel-web spiders evolved millions of years ago, toxins in its venom mainly targeted their natural prey: insects such as cockroaches and flies.

In some species females have the option of eating males after mating, whereas in others the males have evolved ways of escaping. (Male funnel-web spiders, for example, use pheromones to knock females unconscious before mating.)
Do Funnel Webs chase you?
Nor do they jump onto, or chase people, or live in houses – these are all urban myths. Dry daytime surface conditions will dehydrate funnel-web spiders and also expose them to birds and lizards. This is why males that have spent the night in search of a female have to seek cover at dawn.
Which is deadlier male or female funnel web?
A team of University of Queensland researchers has revealed why male funnel web spiders develop much deadlier venom than their female counterparts. Led by UQ’s Associate Professor Bryan Fry, the team has spent 20 years investigating delta-hexatoxins, the venom peptides that make funnel web spider venom so dangerous.

How do you find a funnel-web hole?
Signs. Funnel-web burrows are distinguished from other holes in the ground by the presence of a series of irregular silk ‘trip-lines’ radiating out from the entrance. Holes are normally found in moist, shaded areas like rockeries, dense shrubs, logs and leaf litter.

What is the difference between a trapdoor spider and funnel-web?
Brown Trapdoor burrows are open (without a trapdoor). Often they are found scattered over lawns. They can be distinguished from Funnel-web burrows by the absence of silk triplines around the entrance. Sigillate Trapdoor burrows are made with soil or litter trapdoors.
Are funnel spiders venomous?
All funnel-web spider bites should be treated as potentially life-threatening, even though only approximately 10% to 15% of bites are venomous. Since the venom from the funnel-web spider bite is highly toxic, all species should be considered potentially dangerous.
Are cats immune to funnel-web spiders?
People and other primates are exquisitely sensitive to funnel web venom but, intriguingly, other mammals such as mice, rabbits, guineapigs, dogs and cats are relatively immune and often survive 100 times the human lethal dosage.
