Some [[Lineage (evolution)|evolutionary lineages]] of [[gastropod]]s have evolved a proboscis. In gastropods, the proboscis is an elongation of the snout with the ability to retract inside the body; it can be used for feeding, sensing the environment, and in some cases, capturing prey or attaching to hosts. Three major types of proboscises have been identified: pleurembolic (partially retractable), acrembolic (fully retractable), and intraembolic (variable in structure). Acrembolic proboscises are usually found in [[parasite|parasitic]] gastropods.<ref>{{cite journal|journal=Malacopedia|issn=2595-9913|edition=Volume 2(4): 22–29|last=Simone|first=Luiz|date=September 2019|title=The proboscis of the Gastropoda 1: its evolution|url=https://www.researchgate.net/publication/336014299}}</ref><ref>{{cite journal|journal=Journal of Molluscan Studies|author=Ball, A.D. and Andrews, E.B. and Taylor, J.D.|title=THE ONTOGENY OF THE PLEUREMBOLIC PROBOSCIS IN ''NUCELLA LAPILLUS'' (GASTROPODA: MURICIDAE) |volume=63|number=1|pages=87–89|date=1997-02-01|doi=10.1093/mollus/63.1.87 |issn=0260-1230|url=https://academic.oup.com/mollus/article-pdf/63/1/87/3011806/63-1-87.pdf}}</ref>
