Proxy variables indicating different life-styles in homogeneous (H; in grey circles or bars) and striped translucent morphs (ST; in white circles or bars). a Carapace shape differences based on geometric morphometric results. Morphotypes are clearly segregated along the first relative warp axis, from a stout carapace outline representative of H individuals, to a more streamlined shape found in ST shrimp. Percentage values represent the relative warps share of the total morphological variation. Dots along carapace margins show the position of landmarks used in the analysis (see Methods). b Substrate fidelity of morphs, over 30 min experimental trials, expressed as the percentage of individuals settled on algal clumps. Whiskers represent ± 1 SE. *p < 0.05; **p < 0.01. c Morph-specific mobility, expressed as individual average swimming distances (in cm) per minute, over 30 min experimental trials. Measurements for mobile shrimp are outliers (filled circles) from baseline movement of sedentary individuals. Dashed lines represent the upper fence delimiting the non-outlier range (see Methods for details)
