Figure 2. Symbolic description of pursuit shown in Figure 1. In this and in subsequent diagrams the primary objective (A) is represented by a black circle, secondary or intermediate objectives by grey circles (B, C, D), and positions assumed by the spider by white circles (S). Vectors representing either the original orientation to the prey position (1) or subsequent reorientation to that position (3) are highlighted in red. Movement by the spider (2) is indicated as a dashed line. Not shown here, vectors representing turns to face secondary objectives or plant positions are shown in black. Here the spider faced its prey (1), turned and ran (2) up to a higher position with a closer map (horizontal) distance to that prey, and then reoriented to face the expected position of that prey (3).
