The culture water in which H. pirardi, H. pscndoligactis or H. fusca had been feeding on excess Artemia when filtered, significantly reduced column contraction frequencies of H. pirardi. In addition, 10"5 M GSH inhibited column contractions in all three species. 4. Relationship between concerts and tentacle and column contractions The experiments whose results were described above indicate that feeding stimuli enhance the frequency of concerts while inhibiting tentacle and column.
