Here we showcase how the geo-tectonic and climatic evolution in South Asia and surrounding landmasses have shaped the biogeographic history of Indoplanorbis exustus, a tropical Asian, freshwater, pulmonated snail. We amplified partial COI gene fragment from all over India and combined this with a larger dataset from South and Southeast Asia to carry out phylogenetic reconstruction, species delimitation analysis, and population genetic analyses. Two nuclear genes were also amplified from one individual per putative species to carry out divergence dating and ancestral area reconstruction analyses. -

Department of Zoology and Aquaculture, Acharya Darwin Ch. and P Padmavathi Nagarjuna University Nagarjuna Nagar, Abstract Andhra Pradesh, India Among the various groups represented in the macrobenthic fauna of the Bay of Bengal at Prakasam P Padmavathi district, Andhra Pradesh, India, molluscs were the dominant group. Molluscs were exploited for Department of Zoology and industrial, edible and ornamental purposes and their extensive use has been reported way back from time Aquaculture, Acharya immemorial. Hence the present study was focused to investigate the diversity of Molluscan fauna along Nagarjuna University the Paleru and Moosy backwaters of Prakasam district during 2016-17 as these backwaters are not so far Nagarjuna Nagar, explored for malacofauna. A total of 23 species of molluscs (16 species of gastropods belonging to 12 Andhra Pradesh, India families and 7 species of bivalves representing 5 families) have been reported in the present study. Among these, gastropods such as Umbonium vestiarium, Telescopium telescopium and Pirenella cingulata, and bivalves like Crassostrea madrasensis and Meretrix meretrix are found to be the most dominant species in these backwaters. Keywords: Malacofauna, diversity, gastropods, bivalves, backwaters 1. Introduction Molluscans are the second largest phylum next to Arthropoda with estimates of 80,000- 100,000 described species [1]. These animals are soft bodied and are extremely diversified in shape and colour. -

ABSTRACT of most mesopsammic “opisthobranchs” within a comprehensive euthyneuran taxon set. During the last decades, textbook concepts of “Opisthobranchia” have been challenged by The present study combines our published morphology-based and, more recently, molecular and unpublished topologies, and indicates that studies. It is no longer clear if any precise distinctions monophyletic Rhodopemorpha cluster outside of can be made between major opisthobranch and Euthyneura among shelled basal heterobranchs, acte- pulmonate clades. Worm-shaped, mesopsammic taxa onids are the sister to rissoellids, and Nudipleura such as Acochlidia, Platyhedylidae, Philinoglossidae are the basal offshoot of Euthyneura.

Glyptophysa (Glyptophysa) Novaehollandica (Bowdich, 1822)
Glyptophysa (Glyptophysa) novaehollandica (Bowdich, 1822) Disclaimer This genus is in need of revision, as the species concepts we have used have not been rigorously tested. Unpublished molecular Glyptophysa (Glyptophysa) novaehollandica Glyptophysa novaehollandica, ventral view of (adult size may exceed 30 mm) head-foot, NW Australia. Photo J. Walker. Glyptophysa novaehollandica, dorsal view of head-foot, NW Australia. Photo J. Walker. Distribution of Glyptophysa (Glyptophysa) novaehollandica. data indicate that the species units we are here using appear to be justified, however they are not accompanied by clear-cut morphological characters that allow separation based on shell characters alone. As the species units appear to be overall concordant with state boundaries, we have used these boundaries to aid delimiting species. This situation is not ideal, and can only be resolved by additional molecular and morphological studies involving dense sampling. Diagnostic features The taxonomy of Glyptophysa is very poorly understood. This is one of several species of relatively smooth shelled Glyptophysa that are variable in shape and in periostracal development (periostracal hairs and spirals can be present), even within a single population. A large number of species-group names are available and it is quite possible that more species occur in Australia. At present we are recognising only three, in addition to G. aliciae. This species is one of three that we are somewhat tentatively recognising (see statement under Notes) that were previsously referred to as Glyptophysa gibbosa (now treated as a synomym of G. novaehollandica). These taxa are in need of revision, as the species concepts we have used have not been rigorously tested. -
Structure and Function of the Digestive System in Molluscs
Cell and Tissue Research (2019) 377:475–503 https://doi.org/10.1007/s00441-019-03085-9 REVIEW Structure and function of the digestive system in molluscs Alexandre Lobo-da-Cunha1,2 Received: 21 February 2019 /Accepted: 26 July 2019 /Published online: 2 September 2019 # Springer-Verlag GmbH Germany, part of Springer Nature 2019 Abstract The phylum Mollusca is one of the largest and more diversified among metazoan phyla, comprising many thousand species living in ocean, freshwater and terrestrial ecosystems. Mollusc-feeding biology is highly diverse, including omnivorous grazers, herbivores, carnivorous scavengers and predators, and even some parasitic species. Consequently, their digestive system presents many adaptive variations. The digestive tract starting in the mouth consists of the buccal cavity, oesophagus, stomach and intestine ending in the anus. Several types of glands are associated, namely, oral and salivary glands, oesophageal glands, digestive gland and, in some cases, anal glands. The digestive gland is the largest and more important for digestion and nutrient absorption. The digestive system of each of the eight extant molluscan classes is reviewed, highlighting the most recent data available on histological, ultrastructural and functional aspects of tissues and cells involved in nutrient absorption, intracellular and extracellular digestion, with emphasis on glandular tissues. Keywords Digestive tract . Digestive gland . Salivary glands . Mollusca . Ultrastructure Introduction and visceral mass. The visceral mass is dorsally covered by the mantle tissues that frequently extend outwards to create a The phylum Mollusca is considered the second largest among flap around the body forming a space in between known as metazoans, surpassed only by the arthropods in a number of pallial or mantle cavity. -
Aplexa Hypnorum (Gastropoda: Physidae) Exerts Competition on Two Lymnaeid Species in Periodically Dried Ditches

The introduction of A. hypnorum into each ditch was followed by the progressive coloni- zation of the entire habitat by the physid and progressive reduction of the portion occupied by the lymnaeid towards the upstream extremity of the ditch. Moreover, the size of the lymnaeid population decreased significantly over the 7-year period, with values noted in 2008 that were significantly lower than those recorded in 2002. In contrast, the mean densities were relatively stable in the sites only occupied by G. truncatula or O. glabra. Laboratory investigations were also carried out by placing juvenile, intermediate or adult physids in aquaria in the presence of juvenile, intermediate or adult G. truncatula (or O. glabra) for 30 days. The life stage of A. hypnorum had a significant influence on the survival of each lymnaeid. In snail combinations, this survival was significantly lower for adult G. truncatula (or O.
