Body bends during swimming is reduced in the N2 wild type worms with developmental MeHg exposure. Day 10 adult worms of the wild type strain were recorded for body bends during a 300-s period. a, average body bends of worms during 0-5 s (first 5 s), 150-155 s (middle 5 s) and 295-300 s (last 5 s) of the swimming period. b. average bending angles of worms during the swimming period. c, representative of bend angles of worms with 0 or 0.05 μM MeHg. Analyses in a and b were performed with t-test. ** p<0.01; *** p<0.001.
