Table 1 Summary results of the mixed three-way analyses of variance testing the effects of morph type (M; greenish-brown or pink), substrate colour (SC; brown or pink) and aquaria (nested in the interaction between main factors) in final hue values measured in Hippolyte obliquimanus individuals after being maintained for five days in artificial or algal substrates

From: Shape, colour plasticity, and habitat use indicate morph-specific camouflage strategies in a marine shrimp
