Family of gastropods
Turritellidae, with the common name "tower shells" or "tower snails", is a taxonomic family of small- to medium-sized sea snails, marine gastropod molluscs in the Sorbeoconcha clade.
They are filter feeders; this method of feeding is somewhat unusual among gastropod mollusks, but is very common in bivalves.
Shell description
The shells of turritellid species have whorls that are more convex and their apertures being more circular than it is in the auger shells, which are similarly high-spired. The columella is curved and the thin operculum has many horns.
