TaxonomyPomacea diffusa was originally described as a subspecies of Pomacea bridgesii.[1] Pain (1960)[1] 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).[1] Cowie and Thiengo (2003)[2] suggested that the latter might deserve full species status, and the two taxa have been confirmed as distinct species by genetic analyses.[1]DistributionThe 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.[1] Non-indigenous distribution of Pomacea diffusa include:
DescriptionPomacea diffusa is known as the spike-topped apple snail, because of its relatively raised spire.[1] It lacks a channeled suture, and overlaps in size with the Pomacea paludosa.[1]The egg masses have an irregular honeycombed appearance, like those of Pomacea haustrum, but are smaller and have a tan to salmon color, although the egg masses are white when freshly laid.[1] Human useIt is a part of ornamental pet trade for freshwater aquaria.[7] ReferencesThis article incorporates CC-BY-2.0 text from the reference.[8] 1. ^{{Cite journal|last=Pain|first=T.|year=1960|title=Pomacea (Ampullariidae) of the Amazon River system|url=|journal=Journal of Conchology|volume=24|pages=421–443|via=}} 2. ^{{Cite journal|last=Cowie|first=R.
