Graphs illustrating the response of C. aspersum to each species’ mucus. a Relative number of contractions of the diverticulum. b Relative intensity of contractions of the diverticulum. c Relative number of contractions of the copulatory canal. d Relative intensity of contractions of the copulatory canal. Mean ± SE is given for each graph. The graphs are obtained by subtracting the mean response of the control species from the response of each species mucous extract for every experimental day. Note that the intensity is shown here as percentages of displacement compared to the control species (e.g. lower percentages indicate a relatively lower response); the control species has 100 % response and 0 % response is based on coordinates of preparations of the species showing zero response. The symbol 1 indicates that C. aspersum is the baseline hence its bar mean is zero. Numbers in parentheses indicate the sample size and the asterisks show the significance according to the Steel method (*p < 0.05, **p < 0.01, ***p < 0.001). For ease of comparison, species are listed according to their order of appearance on the phylogenetic tree
