The Sydney Funnel-web Spider is a very aggressive species and one of the deadliest spiders in the world. The cephalothorax is almost hairless and appears smooth and glossy black. The abdomen is black, dark brown or purplish in colour. The body and legs are covered with fine hairs. The male has more slender legs and a spur on the third segment of the second leg. This tiny spur is used to hold the female`s fangs during mating. Funnel-webs are extremely aggressive spiders and when threatened they raise their front legs high off the ground and point their fangs forward ready to strike. When they strike they drive the fangs down with force and speed.
