Abstract: The effects of different concentrations of several heavy metals on the righting behavior of Littorina planaxis were studied. Part of the animals' shells were removed they were then submerged in sea water that contained different concentrations of cadmium, copper, lead and silver. The effects of these treatments were assayed by timing the animals' righting response. The results obtained show that cadmium, copper, and silver have significant effects only at high concentrations. Lead was shown to have no significant short-term effects.
