Introduction
The screw snails are a family of exclusively marine snails
that are native to the tropical seas.
They are almost exclusively predatory forms.
The species of screw snails hunt marine worms buried in the sand,
which are usually paralysed with the help of the venom gland.
They live exclusively in the warmer seas, mainly in the Indo-Pacific region.

The shells are almost exclusively slender, highly conical with numerous convolutions.
The mouth is small and, depending on the shape of the shell, narrow to broadly oval.
The lower edge is barely extended.
They still have a thin operculum on the small base, with which the mouth can be closed.
