Figure 6 in How jumping spiders (Araneae: Salticidae) find and use indirect routes to reach their sighted objectives

Figure 6. Hypothetical pursuit of nearby prey (primary objective) in three dimensions with a route that was not coplanar. In this example the entire route would be visible to the spider at all times during the pursuit. 1, Spider facing the prey (A). 2, Spider facing a secondary objective (B) selected for its visible connection to the primary objective (A). 3, Spider moving down (the only option available) to complete segment one of this pursuit. 4, Spider reorienting to face the primary objective (A), to begin the second segment of pursuit. 5, Spider facing the secondary objective (B). 6, Spider facing a tertiary objective (C) selected for its visible connection to the secondary objective (B). 7, Spider facing a quaternary objective (D) selected for its visible connection to the tertiary objective (B). 8, Spider moving to the quaternary objective (D). Movement toward the quaternary objective rather than toward the tertiary objective would indicate that the spider recognized that the elevated position of the latter was not directly accessible. 9, Spider reorienting to face the primary objective (A) to begin a third segment of pursuit. 10, Spider moving toward the primary and secondary objectives. 11, Spider reorienting to face the primary objective (A), beginning a fourth segment of pursuit. 12, Spider moving directly toward the primary objective (A).
