The Scaphopods or 'tusk-shells' form a small but distinctive class of molluscs with a fossil record extending back to the early Devonian. Although better known than either the Caudofoveata or the Solenogastres, they have received comparatively little attention.
The Scaphopoda appear to occupy a position intermediate between the Gastropoda and the Lamellibranchiata: the presence of a univalve shell, a buccal mass with a radula and the nature of the nervous system are characteristic of the gastropods while the digging foot, lack of cephalisation, fused mantle which is open at both ends and bilateral symmetry are typical of bivalves.
