Scale bar is 100 μm. o = operculum mp = metapodium to where is the operculum attached at cil = cilia s = shell v = ciliated velum.
context_page_description: Berghia stephanieae is a species of sea slug, an aeolid nudibranch. It is a marine gastropod mollusc in the family Aeolidiidae. It was previously known as Aeolidiella stephanieae.
context_section_description: Late veliger stage (20-25% of development): The operculum is present and the foot becomes thicker and longer, the embryo hatches shortly prior to metamorphosis. Swimming is accomplished by ciliary beats of the velar cilia.
  Metamorphosis (25-30% of development): Usually one day after hatching the larvae settle on the bottom and retract into the larval shell. During the process of metamorphosis, which does not take longer than 48 hours, the animals cast off their larval shell.
