Pomacea columellaris explained

Pomacea columellaris is a South American species of freshwater snail in the apple snail family, Ampullariidae.^[1]

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.^[2] They were named for their notable columella, comparable to those of Helix land snails.^[3] In 1904, Dall proposed a section or subgenus of Ampullaria (later treated as synonymous with Pomacea) called Limnopomus,^[4] with A. columellaris as the type species.^[5] After 1991, Limnopomus was also considered synonymous with Pomacea.^{[6] [7]}

Shell description

The species has a heavy, oval shell with a sharp spire.^[8] Its operculum is corneous and able to retract inside the shell's aperture.^{[8] [9]} They lack an umbilicus^[3] and are often yellow in color.^[9]

Distribution

P. columellaris is found in rivers in the highlands of Venezuela, Colombia, Ecuador (Pastaza Province),^[10] and Peru.^[4]
