scaura: (1) transition from holoblastic cleavage to superficial cleavage, (2) germdisc condensation, (3) germband formation and elongation, (4) germband flexure and limb bud formation, (5) limb bud elongation and segmentation, and (6) dorsal closure and reversal of cephalic direction.
The transition from holoblastic to superficial cleavage was observed in stage 5 of gammarid embryo- genesis (Scholtz and Wolff, 2002; Browne et al., 2005).
