Lipid content of the egg decreased significantly from E-Stage XIII ( ± (SEM) mg) to E-Stage XV ( ± mg) (P = , t = ) and from L-Stage I ( ± mg) to L-Stage III ( ± mg) (P < , i = ) (Fig. 5a). As lipid content decreased, metabolizing mass increased significantly between E-Stage XIII ( ± mg) and E-Stage XV ( ± mg) (P --'- , / --•• ) (Fig. 5b). Metabolizing mass increased throughout embryonic development, although egg membrane surface area did not change significantly. The metabolizing mass of the first larval stage ( ± mg).
