The molluscs
Gastropods: as snails. They have a single spiral shell and move crawling on their muscular foot secreting mucus also helping to make the surface more slippery.
A curious peculiarity, which covers both the bivalve gastropods, is that they have an open circulatory spiral seashells system, ie they are devoid of veins and arteries, and the blood directly surrounding their internal organs.
Cephalopods: as cuttlefish, spiral seashells squid and octopus. Molluscs are more complex and evolved because they have a circulatory system very similar to ours. Their foot muscle is not unique but is divided into tentacles equipped with suction cups. They also have a great propulsion system through which water enters a kind of trap and being ejected with speed allows them to move and swim with efficiency.
