Key for Figures 1 to 4. E, endoderm; F, foot; L, larval liver; R, radula sac : S, shell gland. usually were visible. Some arrested veligers became hydropic, showing a swollen foot or body. The vesicular condition of the body apparently resulted from a reduction in the number and size of the large endoderm cells. The vesicular foot was associated with a reduction in mesenchyme tissue. Arrested veligers usually lived for 3-6 days without undergoing further differentiation. The cobalt- arrested veligers were similar morphologically to "aspecific snails" obtained from.
