Essentially, haplotrematids have fewer cusps than most snails, but they are considerably elongated, suitable for the predatory life they follow. Members of this family have been given the common name "lancetooth" snails, presumably based on this last anatomical characteristic.

The lower pair, oral tentacles, provide the slug's sense of smell. Both pairs can retract and extend themselves to avoid hazards, and, if lost to an accident ...
Neohelix albolabris is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Polygyridae.
