The effect of some biologically active substances (acetylcholine, serotonin, octopamine, sodium nitroprussid and FMRF-amide) on the motility of the Cryptocotyle lingua cercariae was studied. Solutions of FMRF-amide, octopamine, and sodium nitroprussid have no statistically significant influence on the motility of C. lingua. Acetylcholine and serotonin in solutions affected the motility through the prolongation of the active phase of swimming. Further research is required to elucidate the mechanisms underlying the cercarial motility.
