Careoradula perelegans is a species of air-breathing land snail, terrestrial pulmonate gastropod mollusk in the family Streptaxidae. [2] [4]
Careoradula perelegans is the only species in the genus Careoradula. [2]
The generic name Careoradula consist of Latin word "careo", that means "lacking" and the word radula. [2]
Careoradula perelegans is endemic to the Seychelles. [2] [4]
The shape of the shell is discoidal. [2] The shell has 6-8 whorls. [2] there are regular ribs on the shell. [2] The umbilicus is open. [2]
The width of the shell is 4.4-6.1 mm. [2] The height of the shell is 1.9-3.1 mm. [2]
The body color is pale yellow. [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]
Careoradula perelegans feeds on carrion. [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. [5]
