Radula and individual tooth of the predatory ghost slug, Selenochlamys ysbryda The number, shape, and specialized arrangement of molluskan teeth in each transverse row is consistent on a radula, and the different patterns can be used as a diagnostic characteristic to identify the species in many cases.

The structure of the radula of these snails (their "teeth") is unusual. 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.
Tympanotonus radula (Linnaeus, 1758) (junior synonym; misspelled genus) Tympanotonos fuscatus , the West African mud creeper , is a species of snail living in brackish water , a gastropod mollusk in the family Potamididae .
An electronmicrograph of the radula ribbon of the species. The inset shows one individual tooth. Because of the slug's white colour and nocturnal habits, and because it is so rarely seen, it was given the species name ysbryda, the word "ysbryd" meaning ghost in the Welsh language. This in turn gave rise to the common name, "ghost slug". This ...
The name chiton is Neo-Latin derived from the Ancient Greek word khitōn, meaning tunic (which also is the source of the word chitin). The Ancient Greek word khitōn can be traced to the Central Semitic word *kittan, which is from the Akkadian words kitû or kita'um, meaning flax or linen, and originally the Sumerian word gada or gida ...
While some species of Radula can produce similar structures, the consistent presence and positioning of these shoots in Dactyloradula helps distinguish it from related genera. [ 3 ] These features, when considered together, provide a reliable way to identify Dactyloradula and support its recognition as a distinct genus.
Cladoradula species typically grow on the bark of trees and shrubs, as well as on shaded rocks in submontane and lower montane forests, where they often adopt a pendant growth habit. They can be found at elevations ranging from 400 to 2,100 metres above sea level. [7] Radula species occur from sea level to approximately 4,000 metres elevation. [12]
