Scytodidae catch their prey by spitting a fluid that congeals on contact into a
venomous and sticky mass. The fluid contains both venom and
spider silk in liquid form, though it is produced in venom glands in the
chelicerae. The venom-laced silk both immobilizes and envenoms prey such as
silverfish. In high-speed footage the spiders can be observed swaying from side to side as they "spit", catching the prey in a criss-crossed "Z" pattern; it is criss-crossed because each of the
chelicerae emits half of the pattern. The spider usually strikes from a distance of and the entire attack sequence only lasts 1/700th of a second. After making the capture, the spider typically bites the prey with venomous effect, and wraps it in the normal spider fashion with silk from the spinnerets. ==Pre social behaviour==
