'''Acteonidae''' is a [[family (biology)|family]] of small [[marine (ocean)|marine]] sea [[snail]]s of the opisthobranch [[suborder]] [[Cephalaspidea]].
==Shell description==
The shell of these sand-dwelling [[micromollusk]]s is small but it is large enough to house the retracted soft parts including the entire [[Mantle (mollusc)|mantle]]. The narrow shell [[aperture (mollusc)|aperture]], which is ovate and pointed on the top, can be closed with an [[Operculum (gastropod)|operculum]]. The thick shell is oviform to [[fusiform]], with a short (sometimes sunken) conical [[apex (mollusc)|apex]]. They have spiral [[sculpture (mollusc)|sculpturing]]. The elongated aperture opens up from narrow at the posterior notch to enlarged at the base. The base of the columella has several characteristic [[plait (gastropod)|plait]]s.
==Anatomy==
The [[radula]] has no central tooth and there are five or six laterals on each side. The teeth are very similar in shape and size across the radula, which is specialised for a diet of [[polychaete worm]]s. The eggs are enclosed in a long, gelatinous mass, which is attached to the substrate with a short stalk.
Further treatment can be found under [[Acteonoidea]] and [[Cephalaspidea]].
==Genera and species within the family Acteonidae==
Genus '''''Acteon''''' <small>Montfort, 1810</small>
