Fig. 10: Video 59 of the predator-exposed treatment of the Þristikla population, non-parasitized.

The video was trimmed to show the moment when the robotic predator was triggered. The camera was set to 160p recording in P mode, with stabilization deactivated. The file format is AVCHD, and the accepted SD card format is exFAT. The robotic predator is constructed using a motor and a belt system, designed so that the tail of the silicone model aligns with the tank’s siphon and stops before reaching the end of the rail.
