 P. schultzi does not respond to prey if the light is under 100 lux ( like a restaurant with only subdued artificial lighting ) , but responds to prey at distances from 6 to 10 centimetres as the light level increases . A test suggested that P. schultzi ′ s hunting is stimulated only by vision , as prey close but hidden caused no response . : 37 A preliminary check showed that lures got the same responses from P. schultzi as live prey , and then more detailed testing with the lures showed that : if the target moved erratically , P. schultzi did not pursue it ; if the target was totally stationary , the spider approached very slow ( between 5 and 100 millimetres per minute ) , with very long pauses in the final stages , and the sequence was not completed in 43 % of cases ; if the lure jiggled on the same spot , P. schultzi approached much faster and the sequence was almost always completed ; if a lure was pulled directly away from P. schultzi , the spider followed , and faster if the lure was pulled , up to a limit ( P. schultzi generally moves very slowly : 34 @-@ 35 ) . : 37 @-@ 38
