Behavioral responses of Nucella lamellosa individuals to the effluent from five different crustaceans. Snails received effluent in a choice apparatus from either the apertural or columellar side of their shells. Responses were pooled across all trials for each stimulus. The percent of snails that turned aperturally in response to a given effluent was compared by means of a Chi-square test to the percentage of all snails that turned aperturally (). = Cancer productus,

Avoidance responses of Nucella lamellosa individuals from two localities to various effluents. A third group of snails was acclimatized in the laboratory for one week with food ('Grappler-lab'). Snails were scored as moving either toward or away from each effluent source in a choice apparatus, and responses were pooled across all trials for each stimulus. The observed number of snails that turned away from each effluent source was compared by means of a Chi-square test to the number expected if they had turned at random ().
