See text Turbonillinae is a subfamily of mostly minute parasitic sea snails, marine gastropod molluscs in the family Pyramidellidae, the pyrams and their allies.

[2][1] This subfamily has been shown to be monophyletic[3] In the taxonomy of Schander, Van Aartsen & Corgan (1999)[4] Turbonillinae is a part of the family Turbonillidae.

[4] Turbonillinae has been one of eleven recognised subfamilies in the family Pyramidellidae (according to the taxonomy of Ponder & Lindberg, 1997).

Instead their long proboscis is used to pierce the skin of its prey and suck up its fluids and soft tissues.

Between the head and the foot, a lobed process called the mentum (= thin projection) is visible.
