Fig. 1. Dorsal view of the experimental arena. The recharging habitat and stage (RECHABS) consists of the cylindrical habitat (H) and octagonal stage (S). Neural telemetry and tag recharging could transpire when the fish was in the habitat or over the stage. The black circle (arrow) represents an opaque barricade that restricted the prey and the toadfish to the stage area. Fish movements were recorded with an overhead video camera (C). Drawing is not to scale.
