The information on reproductive characteristics of more than 100 species of the pulmonate
molluscs (clutch size, egg size, hatching success, etc.) is summarized. It is shown that the …

Among the 24 native clausiliids, 15 were subject to laboratory observations. Eleven of them
were found to be oviparous, three–egg retainers and one–ovoviviparous. Batches …

The morphology‐based species delimitation of the land snail genus Formosana
(Clausiliidae) was questioned, due to the high intraspecific variability and interspecific …

Most of the present knowledge on animal reproductive mode evolution, and possible factors
driving transitions between oviparity and viviparity is based on studies on vertebrates. The …

Current zoological research may benefit in many ways from the study of old collections of
shells. These collections may provide materials for the verification of broad zoogeographical …

The maturation, growth and reproduction of Alinda biplicata in the laboratory were studied
over a five-year period. The snails were kept in pairs and groups of a few individuals. The …

This study investigates the natural diet and breeding behaviour of Indrella (Ariophantidae), a
monotypic snail genus endemic to the Western Ghats in India. Our observations show that …

Although generally considered rare in gastropods, septation has long been noted in
turritellids, but functional hypotheses do not survive strong scrutiny. Here we outline a …

Shell decollation is a growth strategy that has been adopted by a number of invertebrate
taxa to offset the metabolic and ecological disadvantages of shell growth. However, little is …

The subterranean radiation of Mollusca has taken place in both main subterranean habitats:
freshwater saturated underground crevices and caves, which are inhabited by species …
