Australian scientists announced the discovery of a new kind of spider. They call it the ballista spider because it builds a web that works like a spring trap.
The trap shoots forward when the spider releases the fibres. This flings ants into the air where they become trapped. Researchers filmed the spider tightening the snare before the sudden release. They spotted it in Queensland’s rainforests, often tucked away under leaves. The discovery shows a spider that uses speed and mechanical power to capture prey.
