Results of mixed-model analysis of variance testing contrasts of seahorse Hippocampus reidi predation rates on prawn Hippolyte obliquimanus colour morphs maintained in different seaweed habitats (as percentage of individuals consumed by seahorses over 2 h trials). The factors ‘prawn morph’ and ‘seaweed habitat’ are fixed, while ‘seahorse ID’ is random and nested in the interaction of main factors. Cochran’s C: Cochran statistic testing variance heterogeneity.
