Abstract: Colloidial carbon injection showed that blood flow is close to the external surfaces in the ctenidium and the mantle facing the mantle groove, and that blood flows through one or the other of these areas just before returning to the heart. A ciliary counter-current was also found associated with each of these surfaces. Field observations showed the mantle vessel network expands and ctenidium withdraws when out of the water. The low intertidal species Acmaea scutum, A. pelta, and A. limatula have larger ctenidia and smaller mantle expansion capabilites than the high intertidal species A. digitalis and A. scabra. Micro-oxygen electrode measurements indicate that both the mantle and the ctenidium are respiratory surfaces, and that the mantle is more effective in aerial conditions and the ctenidium in submerged conditions.
