Spike-topped Apple Snail
''Pomacea bridgesii'', common names the spike-topped apple snail or mystery snail, is a South American species of freshwater snail with gills and an operculum, an aquatic gastropod mollusk in the family Ampullariidae. These snails were most likely introduced to the United States through the aquarium trade. Subspecies * ''Pomacea bridgesii bridgesii'' (Reeve, 1856) * ''Pomacea bridgesii diffusa'' (Blume, 1957) Anatomy Mystery snails possess structurally complex eyes at the tip of a cephalic eyestalk. They are able to regenerate the eye completely after amputation through the mid-eyestalk. They are born with both gills and lungs. Mystery snails also possess a siphon which is a small tube used to breathe air. They frequently surface to breathe. Distribution The native distribution of this snail is Bolivia, Brazil, Paraguay and Peru , image_flag = Flag of Peru.svg , image_coat = Escudo nacional del Perú.svg , other_symbol = Great Sea ...

Pomacea Diffusa
''Pomacea diffusa'', common name the spike-topped apple snail, is a species of freshwater snail, an aquatic gastropod mollusk in the family Ampullariidae, the apple snails. Taxonomy ''Pomacea diffusa'' was originally described as a subspecies of '' Pomacea bridgesii''. Pain (1960) argued that ''Pomacea bridgesii bridgesii'' was a larger form with a restricted range, with the smaller ''Pomacea bridgesii diffusa'' being the common form throughout the Amazon Basin (Brazil, Peru, Bolivia). Cowie and Thiengo (2003) suggested that the latter might deserve full species status, and the two taxa have been confirmed as distinct species by genetic analyses. Distribution The type locality of ''Pomacea diffusa'' is in the city of Santa Cruz de la Sierra, Bolivia, although the species is widespread throughout the Amazon Basin. Non-indigenous distribution of ''Pomacea diffusa'' include: * Thompson recorded this species (as ''Pomacea bridgesii'') in Florida in Monroe, Miami-Dade, ...

Freshwater Snail
Freshwater snails are gastropod mollusks which live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a shell, with very few exceptions. Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung (e.g. '' Ampullariidae''). Most feed on algae, but many are detritivores and some are filter feeders. According to a 2008 review of the taxonomy, there are about 4,000 species of freshwater gastropods (3,795–3,972). At least 33–38 independent lineages of gastropods have successfully colonized freshwater environments. It is not possible to quantify the exact number of these lineages yet, because they have yet to be clarified within the Ce ...
