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