TitleJuveniles of Cavolinia inflexa (Lesueur, 1813) and Cavolinia longirostris (de Blainville, 1821), their discrimination and development (Gastropoda, Pteropoda)
JournalBulletin Zoologisch Museum
AbstractIn C. inflexa the mantle gland and its border show twenty-two bands. Differences in banding with C. longirostris are discussed. It appeared to be possible to discriminate the soft parts of juveniles in both species. Of special value for discrimination is the shape of the lateral appendages. The shells can be distinguished by the relative length of the caudal spine, which is longer in C. inflexa than in C. longirostris. Different developmental stages of C. longirostris are described and those of C. inflexa are added for comparison. While for the latter species the soft parts grow larger parallel with the increment of the shell, this is not the case in C. longirostris, due to the occurrence of minute stages and shedding of the caudal spine. The differences in shedding between C. longirostris and Diacria are described.
