Abstract:
Three different invertebrate species (pond snails, shore crabs, and soil nematodes) were placed within an arena with a single patch of food. All three invertebrates shared similarities in movement styles, and exhibited a difference between within- and between-patch path morphologies. The foragers' pathways within a patch are consistent with area restricted searching. Within-patch movement often resulted in spiraling and meandering pathways. Paths between patches more closely resemble a straight line, with longer paths between turns and smaller turns than within-patch movements. That these behaviors are shared by disparate invertebrate and vertebrate taxa indicates that the behavior is strongly selected for and may have evolved early in metazoan evolution.
