Sydney Funnel-webs are shiny, dark brown to black spiders with finger-like spinnerets (silk-spinning organs) at the end of their abdomen. Males have a large mating spur projecting from the middle of their second pair of legs. If threatened, Sydney Funnel-webs show aggressive behaviour, rearing and displaying their impressive fangs.
