  1. At the individual level, the number of correct choices out of the total number of trials for a given quantitative pair was tested (binomial test) against random (50% correct); at the group level, the success rate (number of correct choices / total number of trials) for a given quantitative pair was tested (Wilcoxon tests) against the median success rate of 0.5. Experiment 1 is the fixed numerosity tests while Experiment 2 is the mixed numerosity tests. The identity of the turtle is indicated by subject ID: MS11, MS14, MS16, MS33 and MS 31. ***p < 0.001; **p < 0.01, *p < 0.05
