Pila (gastropod)

	Pila (gastropod) ''Pila'' is a genus of large freshwater snails with an operculum, African and Asian apple snails, aquatic gastropod mollusks in the family Ampullariidae, the apple snails. Distribution Distribution of the genus ''Pila'' include Africa, Madagascar, southern Asia and Indo-Pacific islands. It is amphibious in nature and can undergo summer sleep or aestivation under drought condition. It is generally found in lakes, pools, and sometimes even in the river streams where aquatic vegetation like ''Vallisneria'', '' Pistia'' are found in large amount for food. External Features When viewed from ''ventral'' side facing the collumella towards the ''observer'', the collumella rotates ''clockwise'' or '' Dextral''. Species Species within the genus ''Pila'' include: subgenus ''Pila'' * '' Pila africana'' (v. Martens, 1886)"''Pila''" The apple ...

picture info	Gastropod Shell The gastropod shell is part of the body of a Gastropoda, gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the Aperture (mollusc), aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group. Shell layers The gastropod shell has three major layers secreted by the Mantle (mollusc), mantle. The calcareous central layer, tracum, is typically made of calcium carbonate precipitated into an organic matrix known as c ...

picture info	Dextral Sinistral and dextral, in some scientific fields, are the two types of chirality ("handedness") or relative direction. The terms are derived from the Latin words for "left" (''sinister'') and "right" (''dexter''). Other disciplines use different terms (such as dextro- and laevo-rotary in chemistry, or clockwise and anticlockwise in physics) or simply use left and right (as in anatomy). Relative direction and chirality are distinct concepts. Relative direction is from the point of view of the observer; a completely symmetric object has a left side and a right side, from the observer's point of view, if the top and bottom and direction of observation are defined. Chirality, however, is observer-independent: no matter how one looks at a right-hand screw thread, it remains different from a left-hand screw thread. Therefore, a symmetric object has sinistral and dextral directions arbitrarily defined by the position of the observer, while an asymmetric object that shows chirality may ...
