Table 1. Effects of flatworm presence and prey concentration on coral feeding rates and flatworm behaviour.Two-way mixed factorial ANOVA, showing main and interactive effects of flatworm presence and ambient prey concentration on prey capture, release and retention by G. fascicularis single polyps, and one-way repeated measures ANOVA demonstrating the effect of prey concentration on flatworm prey capture, prey stolen, flatworms observed and cumulative flatworm time (n = 9).
