  • 1. Funnel Web Spiders by Nate
  • 2. Funnel Web Spiders
    • Description
    • Funnel-web spiders are generally shiny, black or grey.
    • Their eyes are usually packed close together.
    • Funnel-web spiders can often be identified by their thick legs and large fangs.
    • Adult Sydney funnel-webs are medium-to-large in size, with a body length ranging from 2 cm to 7 cm.
  • 3. Funnel Web Spiders
    • Food
    • Funnel-web spiders eat insects and other arthropods such as
    • Beetles
    • Cockroaches and
    • Snails
    • They also eat small vertebrates such as lizards and frogs.
  • 4. Funnel Web Spiders
    • Where they live 
    • Funnel-web spiders are found in coastal and mountain areas of eastern and southern Australia. Funnel-web spiders are found in:
        • Queensland
        • New South Wales
        • the Australian Capital Territory
        • Victoria
        • South Australia
        • Tasmania
    • The Sydney funnel-web spider is found mainly in Sydney, within about 100 km of the city.
    • Male Sydney Funnel-web spiders have a habit of wandering into backyards and falling into suburban swimming pools, where they can survive many hours.
  • 5. Funnel Web Spiders
    • Their web
    • Funnel-web spiders live in burrows in sheltered positions in the ground, or in stumps, tree trunks or ferns above the ground.
    • They usually build silk-lined tubular burrow retreats with collapsed "tunnels" or open "funnel" entrances from which irregular trip lines spread out over the ground.
    • Their burrows are lined with white silk and several strong strands of silk at the entrance.
  • 6. Funnel Web Spiders
    • Their Life Cycle
    • Female funnel-web spiders are long-lived, possibly up to 20 years.
    • Female funnel-web spiders live their entire lives inside the burrow, only going out momentarily
        • to grab passing prey.
    • Young spiders are raised inside the burrow. After the first couple of moults female funnel- web spiders leave the maternal burrow, going on foot to build their own burrow.
    • Young male spiders remain in the burrow until their final adult moult. Males mature at 2-3 years then leave the burrow in search of a mate.
  • 7. Funnel Web Spiders
    • Their bite - venom
    • Funnel-web spider venom is highly toxic, and all species should be considered dangerous.
    • The venom affects the nervous system.
    • Bites by males of two large species, the Sydney funnel- web and northern tree funnel-web, have resulted in death.
    • Bites can be lethal within 40 minutes if not treated. An anti-venom is available.
  • 8. Funnel Web Spiders
    • Interesting Facts
    • Funnel-webs can survive 24 to 30 hours under water.
    • There are at least 40 species of funnel-web spiders.
    • Since the introduction of Anti-venom in 1980 there have been no deaths from funnel-web bites.
    • Females can live for several years in their burrow without leaving it.
