As they gradually get waterlogged, their buoyancy decreases and they eventually sink and drown. Funnel-webs have been known to survive 24-30 hours under water.

The tunnel leads back into a short surface chamber from which the burrow descends. The burrow is often weakly silk-lined and rarely more than 30 cm deep .

When a beetle, cockroach, or small skink, typical items of funnel web food, walks across the lines, the spider senses the vibrations and races out to grab its meal. The prey is quickly subdued by an injection of venom from the spider's large fangs. Funnel-web spiders may also forage on the surface in the vicinity of the burrow.
