The land snail species Drymaeus virgulatus (Férussac, 1821) is recorded in St. Kitts the form of 21 complete or fragmented shells collected on island November 2019. were backshores South Frigate Bay and Majors Bay, while shell fragments come from naturally exposed sections North sand ridge, where they date to pre-Columbian period. This evidence therefore attests past presence this island. absen...

Xeropicta Monterosato is a pulmonate xerophilous snail genus of the family Geomitridae. It distributed in eastern Mediterranean and Black Sea region also Asia Minor, Ukraine, Caucasus, Middle East Iran. No species this was known from Serbia until now. Here, we present first record Serbia. Morphological, anatomical ecological characteristics as well its variation are discussed. Because wide shel...

Abstract Snail ( Achatina fulica ) is one of the sources duck fodder commonly used by local breeders to meet protein needs poultry farms. However, its shells as a by-product are rarely and just become waste. To overcome this problem, we try utilize waste be source bioceramic. contain lot calcium which can precursor make bioceramics. One bioceramics that has potential tricalcium phosphate (TCP) ...

Objective: An experiment was conducted to investigate the effects of citrus brown snail powder as a source of calcium on growth performance, tibia characteristics, immune response and blood metabolites in broiler chickens.  Methods: One hundred and eighty 1-day old chicks were randomly distributed into four treatments, each of which had three replicates. Each replicate contains 15 chicks. The t...

In 2007, we published an article by Justin Gerlach reporting that the population of the Aldabra banded snail, Rhachistia aldabrae, had declined during the latter part of the twentieth century and had become extinct in the late 1990s [1]. This conclusion was based on the analysis of data from a range of shell collections made across the different islands of the Aldabra atoll from 1895 through to...

We explored how functional diversity among predators of the freshwater snail Physa creates an adaptive trade-off for the snail’s shell morphology. Physid shells range continuously between elongate and rotund in overall shape. The protection conferred by alternative shell shapes depends on the mode of attack employed by predators. Predators attack Physa primarily through shell entry (by crayfish...

Community service in the form of domestic liquid waste treatment at Banksa Suci (Cisadane River Garbage Bank) Ciheuni is motivated by wastewater flowing into Cisadane river and passing through park which has been polluted with black water showing. The comes from area around consists residential areas, offices hospitals. Polluted that flows can contaminate body its ecosystem. This activity aims ...

The spiral patterns of snail shells exhibit chirality, or “handedness.” These often heavily favor the dextral (right-handed, clockwise) over sinistral (left-handed, phenotype. While developmental pathways resulting in each enantiomorph (non-superimposable mirror image form) have been studied extensively, there has limited investigation into how emphasis on one direction other may confer surviva...
