Figure 14 in Maratus tiddalik, a new peacock spider in the flavus group from Western Australia (Araneae: Salticidae: Euophryini)

Figure 14. Sequential video frames (25 fps) showing a fixed single leg III wave by a male Maratus tiddalik. Movement and elapsed time (large blue arrow) relative to the previous frame is shown. Each wave was a sudden movement, at a rate of ~2/s. This is thought to represent advertisement when the male is not certain of a female position.
