This chapter explores the evolution and phylogeny of the molluscan class Scaphopoda. It describes the main features of scaphopods including their shell, mantle and mantle cavity, feeding habits, digestive tract, and nervous system. It provides a brief account of the history of classification and phylogeny of scaphopods and characterizes its two main clades, Dentaliida and Gadilida. It stresses the need to increase taxonomic sampling and to develop better repositories of material suitable for molecular analysis in order to understand better the scaphopod phylogeny.
