Post-larva withdrawing the visceral mass from the shell (SH). FIGURE 14. Post-larva immediately after shell loss. Note the left ceras (C). FIGURE 15. Post-larva at 10 hours after shell loss showing the initial expansion of the cephalic epithelium to form the oral hood (OH). Inset: lateral view of a post-larva showing a ceras (C) and the oral hood (OH). FIGURE 16. Post-larva at approximately 36 hours after shell loss showing the cerata (C), the dramatic enlargement of the oral hood (OH), and the buds of the initial hood tentacles (HT). The developing rhinophores (R) appear as two crescent-shaped ridges on the dorsal surface of the oral hood. 127.
