Overall swimming performance and thigmotactic behavior of male and female offspring prenatally exposed to peanut oil or chlorpyrifos (CPF).

	Peanut Oil		CPF
	Male	Female	Male	Female
Total distance (m)	37.30 ± 0.49	36.67 ± 0.66	36.15 ± 0.67	35.8 ± 0.68
% Time in wall zone	23.3% ± 2.8*,†	33.5% ± 2.2	35.1% ± 3.3	35.7% ± 3.5
% Distance in wall zone	21.3% ± 2.8*	29.6% ± 2.0	31.4% ± 3.1	32.6% ± 3.2

Thigmotactic behavior was defined as the percentage of time and the percentage of distance animals swam in a 20 cm-wide zone from the wall of the pool. Results are presented as mean ± SEM of measures obtained during the first probe test from the same animals as in Fig. 4. According to the random effect ANOVA model followed by Tukey-Krammer post-hoc test for pairwise comparisons:

^*p < 0.05 (peanut oil-exposed males compared to peanut oil-exposed females);

^†p < 0.05 (peanut oil-exposed males compared to CPF-exposed males).
