If, in contrast, the culture water in which the hydra had been feeding for a 15 minute period was changed, the contraction frequencies were significantly higher (P < ) than unfed controls (Fig. 6A). This indicates that the ingestion of Artemia itself enhances column contractions while substances liberated to the medium during feeding inhibit them. Inhibition of column contractions occurs when hydra are exposed to
