Funnel web spiders are a group of highly venomous spiders found in Australia. They are known for their large size, powerful fangs, and distinctive funnel-shaped webs. One of the most well-known species of funnel web spider is the Sydney funnel web (Atrax robustus), which is found in the eastern coastal region of Australia, including Sydney.
Description:
The Sydney funnel web spider is a large, robust spider with a shiny black or dark brown body and dark, stocky legs. The males are smaller than females, with a body length of up to 2.5cm, while females can grow up to 4cm in length. The Sydney funnel web spider is one of the most venomous spiders in the world, with a venom that is highly toxic to humans. Its fangs are strong enough to pierce through shoes and fingernails, making it a potentially deadly spider.
Habitat:
The Sydney funnel web spider is found in the eastern coastal region of Australia, including Sydney, and can be found in a range of habitats, including forests, woodlands, heathlands, and suburban areas. It prefers moist and sheltered habitats, such as under rocks, logs, and in burrows. In urban areas, it can be found in gardens, backyards, and even inside houses.
Life cycle:
The Sydney funnel web spider has a typical spider life cycle, with females laying eggs in a silk cocoon. The young spiders hatch from the cocoon and go through a series of molts as they grow. Male Sydney funnel web spiders typically reach maturity at around 2-3 years of age, while females take longer to mature, typically reaching maturity at around 4-5 years of age. After mating, the male Sydney funnel web spider dies, while the female can live for several years.
Behavior:
The Sydney funnel web spider is an aggressive spider that will readily defend its territory. It is most active during the warmer months of the year, from November to February. The spider will often leave its burrow during this time to look for a mate, and this is when most spider bites occur.
Are they dangerous?
Yes, the Sydney funnel web spider is one of the most dangerous spiders in the world, with a venom that is highly toxic to humans. Bites from the Sydney funnel web spider can be life-threatening if not treated promptly. The venom of the Sydney funnel web spider contains a potent neurotoxin that can cause symptoms such as sweating, muscle spasms, and breathing difficulties. In severe cases, the venom can lead to paralysis and death.
Treatment:
If you suspect that you have been bitten by a Sydney funnel web spider, it is important to seek medical attention immediately. The first aid treatment for a spider bite is to apply a pressure bandage to the affected limb and immobilize it. This can help to slow the spread of venom throughout the body. Anti-venom is available for the treatment of Sydney funnel web spider bites and is highly effective if administered promptly.
Prevention:
The best way to prevent a Sydney funnel web spider bite is to take precautions when working in areas where the spider is known to occur. This can include wearing gloves and boots, using a torch to illuminate areas where spiders may be hiding, and taking care when lifting rocks or other objects. If you live in an area where Sydney funnel web spiders are common, it is important to take steps to make your property less attractive to spiders. This can include keeping your lawn and garden tidy, removing piles of leaves and debris, and sealing up any gaps or cracks around your home.
