Supplemental Information

Supplemental information 1

Figure S1: Whether or not measurements were taken from paper or physical samples has a significant effect was tested using linear regression and whether the measurement was taken from a specimen or paper as a factor. There was a significant relationship betweenlog eye diameter and carapace length (Ed = 0.79 * Cl – 1.28, r 2 = 0.623, F=241.9, d.f. = 2,290, p<.0001) but the source of the measurement was found to be significant (p<0.0001). The decision was taken therefore to use only measurements from physical specimens for analyses.

Supplemental figure 2

Figure S2: Relative eye diameter (eye diameter / carapace length) of decapod specimens collected between 2002 and 2010. No pattern is evident (Kruskal-Wallace = 3.582, p-value = 0.8927) that suggests we should not use animals from collections because of possible shrinkage.
