Pomacea columellaris is a South American species of freshwater snail in the apple snail family, Ampullariidae.{{Cite journal|last1=Cowie|first1=Robert H.|last2=Thiengo|first2=Silvana C.|date=2003|title=The apple snails of the Americas (Mollusca: Gastropoda: Ampullariidae: Asolene, Felipponea, Marisa, Pomacea, Pomella): A nomenclatural and type catalog|url=https://www.biodiversitylibrary.org/page/25129440#page/68/mode/1up|journal=Malacologia|volume=45|page=60|access-date=September 9, 2021|via=BioStor}}
Taxonomy
Pomacea columellaris was originally described as Ampullaria columellaris by Augustus Addison Gould in 1848, based on a holotype shell collected during the United States Exploring Expedition from 1838-1842.{{Cite journal|last1=H.

Shell description
The species has a heavy, oval shell with a sharp spire.{{Cite web|title=Pomacea columellaris (Gould, 1848)|url=https://www.applesnail.net/content/species/pomacea_columellaris.htm|access-date=2021-09-12|website=www.applesnail.net}} Its operculum is corneous and able to retract inside the shell's aperture.{{Cite journal|date=1925|title=Studies in Ampullaria|journal=Nature|language=en|volume=116|issue=2912|pages=275|doi=10.1038/116275a0|bibcode=1925Natur.116Q.275.|s2cid=4136804|issn=1476-4687|doi-access=free}} They lack an umbilicus and are often yellow in color.
Distribution
P. columellaris is found in rivers in the highlands of Venezuela, Colombia, Ecuador (Pastaza Province),{{Cite book|last1=Rodriguez|first1=Modesto Correoso|url=https://enaca.org/?id=931|title=Biology and Management of Invasive Apple Snails|last2=Espinosa|first2=Esteban|last3=Rodriguez|first3=Marcela Coello|publisher=Philippine Rice Research Institute|year=2017|isbn=978-621-8022-25-6|editor-last=Joshi|editor-first=Ravindra C.|location=Science City of Muñoz|pages=261|chapter=Pomacea canaliculata in Ecuador: a recent pest with multiple implications|editor-last2=Cowie|editor-first2=Robert H.|editor-last3=Sebastian|editor-first3=Leocadio S.|chapter-url=https://www.cabi.org/ISC/abstract/20173354473}} and Peru.
