From: Calcium ions in the aquatic environment drive planarians to food

Fig. 6

Calcium ions are required for and improve food intake. a. Feeding indexes of D. japonica in Kanatani water lacking calcium ions (Ca++ (−)), Kanatani water containing a low concentration of calcium ions (0.1x Ca++), original Kanatani water (1x Ca++) or Kanatani water containing excess calcium ions (10x Ca++). b. Feeding indexes of S. mediterranea under the same conditions as tested in D. japonica. n = 10; NS, not significant; *, p < 0.05; **, p < 0.01; ***, p < 0.005 (Wilcoxon test)
