Key Visual Features
The Sydney funnel-web spider is a large, heavy-bodied burrowing spider with a distinctive glossy appearance:
- Color: Uniformly dark brown to glossy black, with a shiny, almost polished-looking carapace on the front body segment.
- Size: Body length of roughly 1-2 inches, with males generally more slender and longer-legged than the bulkier females.
- Fangs: Large, forward-pointing fangs that are noticeably bigger than those of most other spiders, visible when the spider rears up.
- Legs: Thick, sturdy legs covered in short hairs, ending in strong claws suited for digging and gripping.
- Body shape: A rounded abdomen that appears almost hairless and smooth compared to the more matte, bristly carapace.
Where and When You'll See One
This species is found in and around the Sydney basin of eastern Australia, favoring moist, sheltered habitats such as gullies, gardens, and bushland with damp soil. It digs a silk-lined burrow with distinctive irregular silk trip-lines radiating from the funnel-shaped entrance. Females rarely leave their burrows, while males wander in search of mates, especially during warm, humid evenings after rain in the warmer months.
Similar-Looking Spiders
- Trapdoor spiders: Build a similar burrow but seal the entrance with a hinged silk-and-soil lid rather than leaving an open, funnel-shaped, trip-lined entrance.
- Wolf spiders: Hunt in the open rather than from a burrow and lack the glossy, smooth carapace of the funnel-web.
- Mouse spiders: Also dark and glossy but have a more compact body shape and different burrow structure without the radiating funnel silk.
Quick ID Checklist

- Large, prominent fangs pointing forward
- Burrow with a funnel-shaped, silk-lined entrance and trip-line threads
- Found in moist, sheltered soil around the Sydney region
- Males seen wandering on warm, humid nights during the mating season
Frequently asked questions
How is the funnel-web's burrow different from other spider burrows?
It has an irregular funnel-shaped entrance lined with silk and surrounded by trip-line threads that radiate outward, unlike the hinged trapdoor of trapdoor spiders.
Why do you see more male funnel-webs out in the open?
Males leave their burrows to search for females during the mating season, which is why they're the ones most often seen wandering at night.
What gives the Sydney funnel-web its glossy look?
Its carapace has a smooth, hard, reflective surface that catches light, distinguishing it from the duller, more matte bodies of many other ground spiders.
What habitat should I check for signs of this spider?
Look in moist, shaded soil in gullies, garden beds, or bushland leaf litter around the greater Sydney region for burrow entrances with radiating silk lines.
