Fig. 4. A female Kelletia kelletii in ventral view. The foot is clinging
to an aquarium glass wall as egg capsules are being laid. Red arrow indicates
the ventral pedal gland (VPG) where final processing of egg capsules occurs.
The shape, size (with respect to overall foot dimensions) and coloration of
the VPG were consistent among the prosobranchs in this study.
