An ark shell is a member of the family Arcidae of saltwater clams or marine bivalve molluscs.
Many molluscs, such as snails, and also creatures like turtles and tortoises have shells.
There are six classes of mollusks. The Gastropoda, Monoplacophores,Polyplacophores(chitons) ,Scaphopods, Bivalves, andCephalopods. The Gastropoda are the most varied and the widest collected shells.
When they first appeared, they all had a hard shell to protect them, as they evolved and natural selection removed some of their relatives, this trait was removed and (like octopodes and squid) the shell became a vestigial structure and was removed.
Gastropods, or slugs and snails, as opposed to molluscs with two shells which are bivalves.
