[2] Digestive system: Careoradula perelegans is unique among other streptaxids, because it has no radula, no odontophore and no retractor muscles associated with these structures.

[2][5] It is the first known terrestrial mollusc and first pulmonate gastropod without radula.

[5] Instead of this, the Careoradula perelegans has strong muscular ridges between mouth and oesophagus.

[5] It has been recorded to feed on dead snail Subulina octona.

[5] It evert an extensive rostrum,[5] that is available in all carnivorous gastropods on the anterior part of the oesophagus,[5] and it uses only muscular peristaltics instead of rasping by radula.
