Figure 1. Nematostella locomotor activity tracking.

Adult Nematostella were separated in wells of six-well plates and were constantly monitored by an infrared camera inside the Noldus DanioVision XT tracking device. White light was automatically turned on and off as required during the 72–108 hours of the experiments. The red dots within the wells’ arenas illustrate the movement paths of the six anemones. Significant differences in the total distance moved were recorded between individuals; therefore, we used the ratios from the maximal value recorded for each animal in each of the experiments.
