Mirror biting and predator avoidance tests behavior endpoint comparisons between control, 1 ppm, and 10 ppm Fe3O4 MNPs-exposed zebrafish groups after two weeks of exposure. (A) Freezing time movement ratio and (B) swimming time movement ratio was analyzed in the mirror biting test. (C) Average speed, (D) freezing time movement ratio, (E) swimming time movement ratio, and (F) rapid movement time ratio were analyzed in the predator avoidance test. The data are expressed as the median with interquartile range and were analyzed by the Kruskal-Wallis test with Dunn’s multiple comparisons test as a follow-up test (n = 20 for the all of the groups).
