Fig. 5 in Morphological requirements in limulid and decapod gills: A case study in deducing the function of lamellipedian exopod lamellae

Fig. 5. The area of every gill lamella of selected first branchial appendages. A. Instar stage 4 of dry−body weight 0.01 g. B. Instar stage 10 of dry−body weight 0.43 g. C. Instar stage 14 of dry−body weight 6.7 g. D. Instar stage 18 of dry body weight 177.09 g. Grey shaded area corresponds to possible newly established lamellae in each instar stage. Darker shade ranges to minimum established number, while lighter maximum. Total respiratory area (T), respiratory area for newly established lamellae of minimum (Nmin) and maximum value (Nmax) are also noted. These ratios relative to the total area are shown in parentheses. The lamellae left to dashed lines lack an osmoregulatory area.

Fig. 4 in Morphological requirements in limulid and decapod gills: A case study in deducing the function of lamellipedian exopod lamellae

Fig. 4. Growth−related change in gill morphology of Limulus polyphemus shown in instar−stage series. A. Mean total respiratory (white bars) and osmoregulatory area for each instar stage (grey bars) and their increment rates (black and grey line graph denotes respiratory and osmoregulatory area, respectively). B. Average total lamellar number for each instar stage (bar graph) and its increment rates (line graph). C. Average area per single lamellae for each instar stage (bar graph) and its increment rates (line graph). The bar graphs should refer to left indexes shown in exponential form (A and C) or in actual numbers (B), and the line graphs right indexes. Error bars denote the maximum and the minimum lamellar numbers. Numbers shown above the columns represent the numbers of examined specimens.
