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.
Turrids are carnivorous, predatory gastropods. Most species have a poison gland used with the toxoglossan radula, used to prey on vertebrates and invertebrate animals (mostly polychaete worms) or in self-defense. [6] Some turrids have lost the radula and the poison gland. The radula, when present, has two or three teeth in a row.
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.
The buccal mass is the first part of the digestive system, and consists of the mouth and pharynx. The mouth includes a radula, and in most cases, also a pair of jaws. The pharynx can be very large, especially in carnivorous species. Many carnivorous species have developed a proboscis, containing the oral cavity, radula, and part of the ...

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]
