The embryo rests on the yolk mass and is surrounded by the vitelline membrane, albumen, shell membrane, and the mineral layer of the eggshell (Ewert, 1985). Very early in development in Mauremys japonica (as Clemmys japonica), the albumen overlying the blastodisc disperses or is absorbed and the blastodisc becomes adherent to the shell membrane (Mitsukuri, 1891). Characteristics: The lattice-like plastral skeleton has separate hyoplastral and hypoplastral bones on each side, and externally the plastron lacks femoral flaps.
