Abbreviations in C: proto, protopod; endo, endopod; exop, exopod: epip. epipod; preepip. preepipod. Bar in A (=B) represents 200 /MIII. (D) Length and width of the adult limb and the lobes. Each bar in D indicates the mean ± 1 SD of 8-16 larvae. (E) Dimensions of the first thoracopod in instars V-VIII. Each bar in E indicates the mean ± 1 SD of 10-18 measurements. regions adjacent to the protopod (Fig. 4A. B, C). The region increased in length, with a slight increase in width through instars V-VIII (Fig. 4E). The medial endite region had grown to 500 ju,m in length and was 140 /urn in width in adults (Fig. ID). Most of this growth was due to cell replication (Fig. 4B, F). The apical surface area increased slowly during instars V-VIII and then increased 3-fold by the adult (Fig. 4B. D, F). Newly formed setae had a mean length of 25 /u,m, an increase in apical surface area of 100 /urn (Fig. 4F). By instar VIII the number of setae increased to 43 and the length reached 87 , attaining a surface area of 547 /o,m2 per seta. In adults, the number of setae had.
