Fig. 7 in Morphological requirements in limulid and decapod gills: A case study in deducing the function of lamellipedian exopod lamellae

Fig. 7. Allometric relationships between respiratory surface and dry−body weight in Limulus polyphemus (dots and solid regression line) in bi−logarithmic coefficients. Abbreviations are: correlation coefficients (r); drybody weight (W); total area for respiratory surface (A); allometric scaling exponent (α). For comparisons, the results on the gills of decapod crustaceans Callinectes sapidus and Libinia dubia are shown in dashed lines, the data are referred to Hughes (1983).
