Figure 1 in The evolution of prey-wrapping behaviour in spiders

Figure 1. Wrapping behaviour of Psalmopoeus reduncus (Theraphosidae). (a) Spider tilts her abdomen to the right as the right posterior spinneret is pressed to the substrate (position indicated by dotted lines followed other position by 0.10 s); (b) the spider presses both posterior spinnerets to the substrate; (c) the spider turns (arrow), swinging its abdomen toward the right while the leading spinneret is lowered and the trailing spinneret is raised; (d) wrapping lines emerging from the trailing, raised spinneret are visible; (e) wrapping lines emerging from the leading, lowered spinneret are visible.
