Xenophora, commonly called carrier shells, is a genus of medium-sized to large sea snails, marine gastropod mollusks in the family Xenophoridae, the carrier snails or carrier shells.[2] The genus Xenophora is the type genus of the family Xenophoridae.
Xenophora is also the name of the quarterly magazine of the French Conchologist Association.[3]
Etymology
The name Xenophora comes from two ancient Greek words, and means "bearing foreigners", so-called because in most species the snail cements pieces of rock or shells to its own shell at regular intervals as the shell grows.[4]
Description
The shells of species within this genus vary from small to large (diameter of base without attachments 19-90 mm; height of shell 21-60 mm), depressed-conical, with narrow to very narrow, simple peripheral edge, non-porcellanous ventrally. Foreign objects are attached to all whorls, with generally more than 30% of dorsal surface obscured by these objects. The foreign objects are usually medium-sized to large.[5] Although the foreign objects are usually mollusk shells, pebbles, or small pieces of coral rock, in some instances a bottle cap has been attached by the snail to its shell.
