Terebridae (Auger shells)

These gastropods have extremely high spired shells with numerous whorls, and the common name refers to the resemblance of their shells to rock drill-type drill bits. The shells of the sea snails in this family are typically shaped like slender augers or screws. In that respect they share certain shell characters with the family Turritellidae, the turret shells.

One characteristic that distinguishes Terebridae from Turritellidae is the short anterior canal or notch in the aperture of the shell. Terebridae shells also tend to have characteristically flattened versus convex whorls, and they often have one or two plaits on the columella.

These snails are sand-dwelling carnivores which live in warmer waters. In most species, a venomous barb similar to that of the cone snails is used to stun and immobilize prey, which typically consists of various marine worms.
