Funnel-web spiders are native to Australia and are considered some of the world's most dangerous spiders due to their highly toxic and fast-acting venom. They are typically found in eastern Australia, particularly in New South Wales, South Australia, Victoria, Tasmania, and Queensland. While they are more common in these eastern states, they can also be found as far west as the Gulf Ranges in South Australia. In Western Australia, the adelaidensis group of funnel-web spiders is isolated to the dry forests of the Gulf Region. This group is unique in that they are the only trap-door-building funnel-web spiders.
| Characteristics | Values |
|---|---|
| Geographical distribution | Funnel-web spiders are found in eastern Australia, Tasmania, and as far west as the Gulf Ranges. They are native to New South Wales, South Australia, Victoria, and Queensland. They are also found in the moist forest regions of the east coast and highlands of Australia, from Tasmania to north Queensland. |
| Habitat | Funnel-web spiders establish their burrows in moist, cool, and sheltered habitats, such as under rocks, rotting logs, or in rough-barked trees. They are commonly found in suburban rockeries and shrubberies, hiding in the shadows. They thrive in sandy clay, shale, or basaltic soils that retain moisture effectively. |
| Behavior | Funnel-web spiders are mostly nocturnal and sedentary. They hunt by waiting in their funnel-shaped webs for prey to fall onto the horizontal web before rushing out to grab it and take it back into the funnel to consume. They are particularly active during mating season. |
| Diet | Funnel-web spiders primarily feed on insects and small vertebrates such as lizards and frogs. |
| Size | Funnel-web spiders range in size from medium to large, with body lengths varying between 1 cm and 5 cm. Some exceptional specimens can reach up to 8 cm. Males tend to have a lighter build compared to females. |
| Color | The body color of funnel-web spiders can vary from black to brown. The hard carapace covering the front part of the body is sparsely haired and glossy. The abdomen is typically dark plum to black and unpatterned. |
| Venom toxicity | Funnel-web spiders possess highly toxic and fast-acting venom, making them one of the most dangerous spiders in the world. Their bites can cause severe injuries and even death within 15 minutes. The male funnel-web spider is considered more dangerous than the female due to its toxic venom, which specifically targets the human nervous system. |
| First aid and treatment | In case of a funnel-web spider bite, it is crucial to promptly apply first aid and seek medical attention. The recommended first-aid treatment is the pressure immobilization technique, which involves wrapping a bandage tightly over the bite site and immobilizing the affected limb to prevent venom circulation. Antivenom is also available for treating funnel-web spider bites. |

What You'll Learn
Funnel-web spiders are found in eastern Australia
Funnel-web spiders are commonly found in eastern Australia, particularly in New South Wales, South Australia, Victoria, Tasmania, and Queensland. They are native to the moist forest regions of the east coast and highlands of Australia, ranging from Tasmania to North Queensland. They are also found in the drier open forests of the Western Slopes of the Great Dividing Range and South Australia's Gulf Region.
Funnel-web spiders are ground-dwelling spiders that build funnel-shaped webs as burrows or to trap prey. They are most commonly found in moist, cool, and sheltered habitats, such as under rocks, rotting logs, or in rough-barked trees. They are known to establish their burrows in protected areas, seeking out cool and humid environments. The burrows are lined with silk, and the most characteristic sign of a funnel-web spider's burrow is the irregular silk trip-lines that radiate out from the entrance, alerting the spider to potential prey, mates, or danger.
Funnel-web spiders are medium to large in size, ranging from 1 cm to 5 cm in body length, with one exceptional specimen reaching 8 cm. They are typically black or brown in colour, with a hard, glossy carapace and sparse hair covering the front part of their body. The male spiders are more lightly built than the females, and they are the ones that carry the toxic venom that attacks the human nervous system.
The Sydney funnel-web spider (Atrax robustus) is one of the most well-known funnel-web spiders and is considered to be one of Australia's most dangerous spiders. It is found in New South Wales, ranging from Newcastle to Nowra and extending westward to Lithgow. The male Sydney funnel-web spider is thought to have been responsible for all 13 recorded deaths from funnel-web spider bites, although no deaths have occurred since the development of antivenom in the early 1980s.

They are not commonly found in Western Australia
Funnel-web spiders are native to Australia and are commonly found along the eastern coast of the country, in states such as New South Wales, South Australia, Victoria, Tasmania, and Queensland. They are also found in the drier open forests of the Western Slopes of the Great Dividing Range and South Australia's Gulf region. However, they are not commonly found in Western Australia.
Funnel-web spiders are ground-dwelling spiders that build funnel-shaped webs as burrows or to trap prey. They are known for their highly toxic and fast-acting venom, making them one of the most dangerous spiders in the world. The Sydney funnel-web spider (Atrax robustus) and the northern tree-dwelling funnel-web spider (Hadronyche formidabilis) are considered to be among the most venomous. These spiders are medium to large in size, ranging from 1 cm to 5 cm in body length, with some exceptional specimens reaching up to 8 cm.
The male Sydney funnel-web spider is particularly dangerous and is thought to have been responsible for all 13 recorded deaths caused by funnel-web spiders. It is capable of causing death within 15 minutes of biting. However, no deaths have been recorded since the development of antivenom in the early 1980s. The male spiders are more lightly built than the females and tend to wander into houses during the warmer months in search of mates.
Funnel-web spiders establish their burrows in protected areas beneath logs and rocks, seeking out cool and humid environments. They are mainly nocturnal and spend most of their lives inside their burrows, venturing out only during mating season or to capture prey. Their prey consists mostly of insects and small vertebrates such as lizards and frogs. While funnel-web spiders are not commonly found in Western Australia, they are widespread in other parts of the country, particularly in the eastern regions.

They are one of the most dangerous spiders in the world
Funnel-web spiders are native to Australia and are regarded as some of the world's most dangerous spiders. They are found in the eastern states of Australia, from Tasmania to north Queensland, and in South Australia's Gulf region. There are over 40 species of funnel-web spiders, with body lengths ranging from 1 to 5 cm, and they are known for their highly toxic and fast-acting venom.
Funnel-web spiders are considered dangerous due to the severity of symptoms caused by their bite, as well as the speed with which these symptoms progress. Their venom contains a type of neurotoxin called delta-hexatoxin, which can attack the nervous system of humans, causing nerves to fire repeatedly. In severe cases, the venom can lead to muscle spasms, a drop in blood pressure, coma, organ failure, and even death within a few hours.
The Sydney funnel-web spider (Atrax robustus) is the species most commonly associated with human fatalities. It is found in New South Wales, ranging from Newcastle to Nowra and extending westward to Lithgow. The male of this species is probably responsible for most of the recorded deaths and medically serious bites. This is because male funnel-web spiders tend to wander during the warmer months, looking for females to mate with, and are thus more likely to come into contact with humans.
Funnel-web spiders construct distinctive funnel-shaped burrows to trap their prey. They are often found in rock gardens, shrubberies, or under logs, and they thrive in cool, humid environments. While funnel-web spiders are dangerous, it is important to note that antivenom has been available since 1981, and there has only been one recorded death since then, highlighting the importance of timely medical intervention.

Funnel-web spiders are ground-dwelling spiders
Funnel-web spiders get their name from the shape of their webs, which have a flat surface and a small funnel-like tube leading to a silken burrow. They build these funnel-shaped webs as burrows to live in or to trap potential prey. The spiders are nocturnal and spend most of their lives inside their burrows, venturing out only momentarily to capture prey or during mating season. They are known to establish their burrows in cool, moist, and sheltered habitats, such as under rocks, rotting logs, or in rough-barked trees.
The Sydney Funnel-web Spider is found in New South Wales, ranging from Newcastle to Nowra and extending westward to Lithgow. They are particularly prevalent in the forested upland regions surrounding the central Cumberland Basin, including areas like the Hornsby Plateau, the foothills of the Blue Mountains, and the Woronora Plateau. Their presence is less common in central-western Sydney and the sandy coastal areas of the eastern suburbs.
Funnel-web spiders are known to be aggressive and will respond quickly when potential prey activates the silk trip-lines they have set up around their burrows. Their prey consists mostly of insects and small vertebrates such as lizards, frogs, beetles, cockroaches, and snails. The male spiders tend to wander into houses during the warmer months, especially in wet weather, in search of female mates.
Bites from funnel-web spiders can be extremely dangerous, and it is recommended to seek medical attention promptly. The pressure immobilization technique is commonly used as first aid for funnel-web spider bites, where a bandage is wrapped tightly over the bite site and extended up the limb to immobilize it. This technique helps prevent the venom from spreading and buys time while waiting for medical treatment.

They are found in suburban Sydney
Funnel-web spiders are native to Australia, and they are commonly found along the eastern coast of the country, in Tasmania, and as far west as the Gulf Ranges. They are also found in suburban Sydney.
Sydney funnel-web spiders (Atrax robustus) are found in New South Wales, ranging from Newcastle to Nowra and extending westward to Lithgow. They are particularly prevalent in the forested upland regions surrounding the central Cumberland Basin's lower, more open country. This includes areas like the Hornsby Plateau in the north, the foothills of the Blue Mountains in the west, and the Woronora Plateau to the south. They are quick to respond when potential prey, such as beetles, cockroaches, small lizards, or snails, activate the silk trip-lines they've set around their burrows.
The dry, flatter areas of Western Sydney and the Cumberland Plain have fewer funnel-web spiders. Their numbers increase again in the foothills of the Blue Mountains. The Sydney funnel-web spider is found from the Central Coast south to the Georges River, extending as far west as Baulkham Hills near the southern end of its distribution. A few records are also known from the Blue Mountains and Wollongong. In Sydney suburbia, funnel-web spiders mostly live in the moist upland forest areas of the Hornsby Plateau to the north and the Woronora Plateau to the south, where sheltered burrow habitats abound in both bushland and gardens.
The Sydney funnel-web spider is one of the most dangerous spiders in the world, and its bite can be deadly. The male of this species is more dangerous than the female as it carries the toxic venom that attacks the human nervous system. The male Sydney funnel-web spider is probably responsible for most of the thirteen recorded deaths and many medically serious bites. The female funnel-web spiders spend most of their lives in their burrows, while the males leave their burrows in search of females in the summer and autumn, which is when they often come into contact with humans.
