Figure 19 (continued on next page). Sequential positions (1-34) occupied by a salticid (Vailimia sp. indet.) as it constructed its retreat in Kasaragod, Kerala, taken from a 59.94 fps video record produced by Prasantha Krishna. At top selected frames from this sequence are composited to show movement from the end of one radius down to the hub (1-15), then movement down and to the stem from the hub with a trailing dragline (15-19), attachment of the dragline to anchor a new radius (22, arrow), followed by return to the hub while climbing beneath the new radius (25-28). 20-24, Individual frames showing trailing dragline as it was extended from the hub (20), hold on that dragline with the claws of leg RIV (21), first movement onto the attached (arrow) dragline (23), and the beginning of a rapid climb back to the hub (24).
