a) Diagram of mirror test aggression assay. Dotted lines delineate the zone of proximity within 5cm of the mirror surface. b) Boxplot of % of 15min assay spent (within 5cm of the mirror surface (Rock vs. sand, Z = −1.98, p = 0.047) c) Number of frontal attacks (Z = 4.20, p < 0.0001) d) Time (s) performing lateral displays during (Z = 4.67, p < 0.0001). Sand species are shown in blue; rock species are in yellow. Species: C. virginalis, CV (n = 10); T. intermedius, TI (n = 8); M. conophoros, MC (n = 15); P. chtimba, PC (n = 17), C. afra, CA (n = 8); L. fuelleborni, LF (n = 9); M. zebra, MZ (n = 9).
