Abstract: The present study was conducted on Morphometric variations of Apple Snail Pila globosa (Swainson, 1822) at foraging selected site of Asian Openbill Stork Anastomus oscitans in Sembanarkoil region, Nagapattinam District, Tamilnadu, India from October 2016 to September 2017. The shell length (3.56 ± 1.05 cm), shell width (2.90 ± 0.93 cm), Aperture length (2.59 ± 0.89 cm), Aperture width (1.39 ± 0.50 cm) and Shell thickness (1.33±0.66 mm) were observed. The total weight in wet condition and (33.14±11.86g) and total weight in dry condition (13.08±4.90g) were also recorded. A Principal Components Analysis (PCA) was made in order to consider character inter- correlations. -
Symbionts and Diseases Associated with Invasive Apple Snails
Symbionts and diseases associated with invasive apple snails Cristina Damborenea, Francisco Brusa and Lisandro Negrete CONICET, División Zoología Invertebrados, Museo de La Plata (FCNyM-UNLP), Paseo del Bosque, 1900 La Plata, Argentina. Email: [email protected], fbrusa@ fcnym.unlp.edu.ar, [email protected] Abstract This contribution summarizes knowledge of organisms associated with apple snails, mainly Pomacea spp., either in a facultative or obligate manner, paying special attention to diseases transmitted via these snails to humans. A wide spectrum of epibionts on the shell and operculum of snails are discussed. Among them algae, ciliates, rotifers, nematodes, flatworms, oligochaetes, dipterans, bryozoans and leeches are facultative, benefitting from the provision of substrate, transport, access to food and protection. Among obligate symbionts, five turbellarian species of the genusTemnocephala are known from the branchial cavity, with T. iheringi the most common and abundant. The leech Helobdella ampullariae also spends its entire life cycle inside the branchial cavity; two copepod species and one mite are found in different sites inside the snails. Details of the nature of the relationships of these specific obligate symbionts are poorly known. Also, extensive studies of an intracellular endosymbiosis are summarized. Apple snails are the first or second hosts of several digenean species, including some bird parasites.A number of human diseases are transmitted by apple snails, angiostrongyliasis being the most important because of the potential seriousness of the disease. Additional keywords: Ampullariidae, Angiostrongylus, commensals, diseases, epibionts, parasites, Pomacea, symbiosis 73 Introduction The term “apple snail” refers to a number of species of freshwater snails belonging to the family Ampullariidae (Caenogastropoda) inhabiting tropical and subtropical regions (Hayes et al., 2015). -

Pomacea Perry, 1810
Pomacea Perry, 1810 Diagnostic features Large to very large globose smooth shells, sutures channelled (Pomacea canaliculata) or with the top of the whorl shouldered and flat at the suture (Pomacea diffusa). Shells umbilicate with unthickened lip. Uniform yellow to olive green with darker spiral bands. nterior of aperture orange to yellow. Operculate, with concentric operculum. Animal with distinctive head-foot; snout uniquely with a pair of distal, long, tentacle-like processes; cephalic tentacles very long. A long 'siphon' is also present. Classification Class Gastropoda Infraclass Caenogastropoda Informal group Architaenioglossa Order Ampullarida Superfamily Ampullarioidea Family Ampullariidae Genus Pomacea Perry, 1810 Type species: Pomacea maculata Perry, 1810 Original reference: Perry, G. 1810-1811.

Type locality: Rio Parana, Argentina. Biology and ecology Amphibious, on sediment, weeds and other available substrates. Lays pink coloured egg masses on plants above the waterline. Distribution Native to North and South America but some species have been introduced around the world through the aquarium trade (Pomacea diffusa) and as a food source (Pomacea canaliculata). Pomacea diffusa has been reported from the Ross River in Townsville in NE Queensland, and from freshwater waterbodies in the greater Brisbane area, pswich and Urangan near Maryborough in SE Queensland. Notes This genus is widely known in the aquarium trade through the so-called mystery snail, Pomacea diffusa. n countries such as the Philippines, Hawaii and parts of SE Asia, the species Pomacea canaliculata (Lamarck) is a serious pest of rice crops. -

The mean calonc value for the community was 5.424 kcal g-' ash-free dry weight (SD f 0.403). This is not significantly different from values from lower latitudes, as has been suggested for planktonic communities. With one exception, the Ascidiacea, there were no significant differences in mean caloric value among major taxa. The lnterspecific distnbution of AFDW caloric value is discussed; present data support the growlng evidence that the natural pattern is symmetrical with values concentrated about a mean of 5.4 to 5.7 kcal g-' AFDW for benthic invertebrates. Caloric equivalents for biomass estimates and large-scale community comparisons may be derived from the regression of dry weight caloric value on percent organic content (dry weight): Y (kcal g-' AFDW) = -0.3897 + 0.0605 X (% organic content). when the organic fraction is determined directly. Two problematical taxa, Porifera and Echinodermata, are discussed and separate regressions are presented.

The Golden Apple Snail: Pomacea Species Including Pomacea Canaliculata (Lamarck, 1822) (Gastropoda: Ampullariidae)
The Golden Apple Snail: Pomacea species including Pomacea canaliculata (Lamarck, 1822) (Gastropoda: Ampullariidae) DIAGNOSTIC STANDARD Prepared by Robert H. Cowie Center for Conservation Research and Training, University of Hawaii, 3050 Maile Way, Gilmore 408, Honolulu, Hawaii 96822, USA Phone ++1 808 956 4909, fax ++1 808.956 2647, e-mail [email protected] 1. PREFATORY COMMENTS The term ‘apple snail’ refers to species of the freshwater snail family Ampullariidae primarily in the genera Pila, which is native to Asia and Africa, and Pomacea, which is native to the New World. They are so called because the shells of many species in these two genera are often large and round and sometimes greenish in colour. The term ‘golden apple snail’ is applied primarily in south-east Asia to species of Pomacea that have been introduced from South America; ‘golden’ either because of the colour of their shells, which is sometimes a bright orange-yellow, or because they were seen as an opportunity for major financial success when they were first introduced. ‘Golden apple snail’ does not refer to a single species. The most widely introduced species of Pomacea in south-east Asia appears to be Pomacea canaliculata (Lamarck, 1822) but at least one other species has also been introduced and is generally confused with P. canaliculata. At this time, even mollusc experts are not able to distinguish the species readily or to provide reliable scientific names for them. This confusion results from the inadequate state of the systematics of the species in their native South America, caused by the great intra-specific morphological variation that exists throughout the wide distributions of the species. -
