The Scaphopods are called tooth or tusk shells because some types resemble miniature elephant tusks. These little-known molluscs are actually relict survivors of a more diverse Paleozoic group known as Rostroconchs. Where they belong on the molluscan evolutionary tree is uncertain; they have been variously grouped with bivalves and cephalopods (it is hard to imagine two more diverse clades of molluscs), such is the lack of consensus in molluscan phylogeny.
