 She spun¹ her snell with silkglands on the underside of her abdomen². The threads harden on contact with air. The trap's set, but she's treading carefully. The web's only sticky in places. She can move around, but others can't. The first bite of the day. She injects the victim's body with venom³ which will turn its guts⁴ to marsh⁵. Escape seems impossible. Thickness for thickness, silk threads can prove stronger than steel. Spiders aren't the only ones who use silk on the battlefield. Spider silk has been used by the military in telescopic gunsights, range finders, even bombs. It's a brutely effective system. Most spiders can catch and eat up to twice their body weight every day. At the end of the day, she might roll up and eat the web itself as a last protein-filled snack. Until then, it's a nonstop cycle, sitting, waiting, pouncing⁶, and eating. A spider can eat a fly from the inside out, but there are more bizarre ways to prepare the dead. Under the floor boards, a dead mouse is being prepared by a pair of burying beetles⁷, undertakers of the natural world.
