RM2AGEBJ7–. Outlines of zoology. res, Molluscs resemble Annelids, but it is probablethat they took their origin from a still lower level. General Characters Molluscs are unsegmented and without appendages. Thesymmetry is fundamentally bilateral, but this is lost in mostGasteropods. The foot—a muscular protrtision of theventral surface—is very characteristic; it tisually serves forlocomotion, but is much modified according to habit. Typically,a projecting dorsal fold of the body-wall forms a mantle, orpallium (Fig. 20Sj c-), i^hich often secretes a single or bilobedshell covering the viscera, and roofs i
