Succineoidei

Suboval ambersnail Catinella vermeta, copyright Ron Matsumoto.


Belongs within: Heterobranchia.
Contains: Succineinae.

The Succineoidei are a group of terrestrial molluscs whose members have optic tentacles that retract that do not invert, and elasmognathous jaws with lateral winged processes and a greatly enlarged attachment plate. The cosmopolitan Succineidae are thin-shelled, conical snails with a greatly enlarged aperture and strongly impressed sutures. Apical whorls have a distinctly nipple-like appearance. The Australasian Athoracophoridae are brightly coloured slugs with the mantle confined to a small triangular area in the centre of the back. The internal shell has been reduced to scattered fragments or granules of calcium (Stanisic et al. 2010).
