clam wiki:
>For other uses, see Clam (disambiguation). Clams are shelled marine or freshwater molluscs belonging to the class Bivalvia. The term "clam" has no taxonomic significance in biology, but is often used to refer to any bivalve (a mollusc whose body is protected by two symmetrical shells) that is not an oyster, mussel, or a scallop, and that has a more-or-less oval shape. An exception is the razor clam, which has an elongate shell that suggests an old-fashioned straight razor. Clams can live to be up to 150 years old -- or perhaps longer (science suspects that some larger quahogs found off the East Coast of the US may be 200 years old).

clip art wiki:
ip art, in the graphic arts, is the use of images either copied or physically cut (hence the term) from pre-existing printed works, either books that have entered the public domain, or books specifically published for such use (which, if they contain images that are not in the public domain, include a license fee in the cover price). It is also not uncommon for large organizations to provide their local divisions or chapters with clip art (either physical or electronic) of their logos, mascots, and so forth, in order that local publications may have a unified appearance. It is also rather common for those producing documents with limited distribution to use images from non-public-domain sources for which they have not paid license fees, such as coloring books, newspapers, magazines, and such, although some magazines, particularly those dealing with hobbies will publish images explicitly licensed to the magazine purchaser for use as clip art.
